6. Research Opportunity Description -

The Office of Naval Research under the Towed Array Reliability FNC program, is interested in receiving white papers (which will be down selected for requests for full proposals) that describe and provide innovative technology solutions for predicting the magnitude and distribution of stress and strain on towed array components during its life cycle including array storage, array deployment, array towed operation and array retrieval. Efforts will be required to characterize both handler and hydrodynamic forces. The tools and methods to be developed under this effort must permit the identification of high stress, high strain, high acceleration, and high cycle areas of the array. This information is critical for creating a reliability-informed towed array system design methodology.

6.1 Background and Approach

Tools for Predicting Array Operational Loading and Distribution:

Hydrodynamics and wake modeling tools may be developed or refined as part of this effort to develop a detailed understanding of hydrodynamic loading on the array during deployment, stowing and retrieval. Concurrent with the development of the hydrodynamic loading, coupled models of the array structure and hydrodynamic field are required to predict hydro-elastic response and the natural modes and frequencies of the array. Structural modeling will require advanced analytical and computational approaches to incorporate the nonlinear materials, anisotropic construction, and complex loading of the array. Advanced modeling methods which improve computational efficiency and fidelity are of interest, but it is anticipated that most of the required advanced capability can be realized with existing software technology. The approach will not be limited to computational mechanics. The effort may establish measurements and signal processing approaches to identify key physics, and to determine scaling relationships for future testing and design efforts. A hybrid modeling approach to combine deterministic and stochastic prediction methodologies in a single tool is also of interest. The predictive tools must support the development of a reliability-informed design process under which designers can predict the effect of array system design iterations on both acoustic performance and system reliability. It must accommodate varying array physical dimensions, and allow description of the structural characteristics and components to a fidelity that would allow accurate measurement of internal feature response. It is anticipated that separate models will be needed to capture towing hydrodynamics and array handling forcing functions. The models should contain sufficient fidelity to predict the time dependent response of the array to external loads, and the manner in which cumulative stresses affect the internal components of the array over use and time.

The models would be exercised over known parameter ranges and operating frequency (towing, maneuvering, and handling) at extreme stresses to observe changes and degradation in system and component physical characteristics. Key outputs of the models would include:

- Summary of cumulative stresses (work),

- Measure of the strength of the major assemblies and array,

- Predicted change in characteristics of components,

- Predicted "global response" at the array level.

Ideally this would be a reliability distribution for the array and/or major subassemblies.

Experimentation efforts:

The model development effort will be supported by a series of experiments that will be conducted in parallel with the FNC. Experiments will be used to establish the parameters that will need to be measured in order to validate the predictive model. This information will inform the design of a highly instrumented “validation” towed array that will be towed by a submarine in another set of experiments needed to gather model validation data. This BAA is seeking proposals only for the FNC portion of this joint effort. Work supporting the validation effort, if desired by the government, would be solicited separately by NAVSEA 073R. However, proposals under this FNC program may address the integration of both the FNC and the validation effort in the context of a single integrated program.

Novel measurement approaches and advanced sensor concepts may be required. The Validation Towed Array, at a minimum, is envisioned to include array motion and tracking, hydrodynamics, tow-cable dynamic sensors, and stress sensors. Measurement and signal processing algorithms, graphical user interfaces or tools shall be developed and employed as needed to reduce the experimental data sets to forms suitable for validation of the tools and methods.

Reliability Based System Design Process:

Validation of the relationship between internal response and external forcing will be conducted empirically and at the component level, potentially using a validation towed array subsection and/or accelerated reliability tests. The application of this modeling toolset would address several development and operational objectives and requirements. Significant information would be available to assist in assessing the impact of design changes under consideration. The models would also support health monitoring and condition-based maintenance application. An end to end block diagram for a towed array reliability model outlined here is shown in Figure 1.

• B: Physics-Based Analytical Model of Towed Array Stresses Under Tow Proposer(s) should address proposed approach for developing a model for the towed array stresses under tow, with the characteristics listed below. This is intended as a highly resolved model, exercised by experienced users. The Analytical model shall predict:

1. The state of stress at any point in the array structure,

2. The effect of flow forces on the array due to cross-flow, turbulence, and ship wake,

3. The failure modes and locations in the array,

4. The effect of dynamic motions in the array structure, including waves and structural oscillations, interacting with the flow.

• C: Physics-Based Analytical Model of Towed Array Stresses in the Handling System Proposer(s) should address proposed approach for predicting the towed array stresses in the handling system, with the characteristics listed below. This is intended as a highly resolved model, exercised by experienced users. The Analytical model shall predict:

1. The state of stress at any point in the array structure,

2. The effect of friction and other traction forces at all points in the handler,

3. The failure modes and locations in the array,

4. The effect of dynamic motions in the array structure, including waves and structural oscillations, caused by the handler under all modes of operation.

• D: Advanced Fluid Flow Models Proposer(s) should describe how code development techniques would be applied in development of improved computational and/or analytical models of nearly incompressible fluid flow to support the needs of the Towed-Array Stresses Under Tow, Task D. Extremely high Reynolds numbers and interaction with ship wakes are a key feature of this flow modeling task. Task D's requirements include the capability to model shear and wall pressure on the moving, flexible array in these flows.

• E: Analytical Modeling of Array Electrical Components Proposer(s) should describe the approach for modeling array electrical components under the use conditions, with the characteristics listed below. The Analytical model shall predict:

1. The state of electrical/thermal stress for any electrical component in the array structure,

2. The failure modes and locations in the array,

3. The effect of array operations on the electrical components.

Metrics for specific aspects of the modeling tasks are listed below:

Hydrodynamic Modeling Metrics:

1. Computation of the zero pressure gradient cylindrical turbulent boundary layer parameters (boundary layer thickness, displacement thickness, momentum thickness, and mean wall shear stress) at moderate to high Reynolds numbers based on momentum thickness. The purely axisymmetric and slightly non-axisymmetric cases should both be considered. The non-axisymmetric case is due to small angles of tow in the zero to ten degree range. This case involves secondary flows and vortex shedding.

2. Computation of the fluctuating wall pressure and fluctuating wall shear spectra for the cases in item 1.

3. Computation of items 1 and 2 (above) for the case of larger angles of attack and array curvature relating to a towed array shape during a tow ship maneuver.

4. The models should be able to incorporate experimental data including the spatially averaged mean wall shear stress, the boundary layer momentum thickness at discrete locations, and wall pressure fluctuations at discrete locations.

Array, Cable, and Drogue Modeling Mechanics:

1. Computation of the array hosewall deformation due to hydrostatic pressure forces (related to depth of tow) and the mean drag load due to turbulent boundary layer skin friction. This should cover the cases of homogeneous hosewall material as a baseline, as well as hosewalls with internal strength members.

2. Computation of the dynamic low frequency (string-like) transverse responses due to distributed forcing.

3. Computation of the dynamic higher frequency responses consisting of bulge waves and extensional waves.

4. Computation of the effects of the layered construction of arrays (that is, internal electrical components, fill fluid, and internal strength members), on items 1 through 3 above.

Towed Array and Handler Model Metrics:

1. Computation of the stresses and strains on the towed array hose and internal array components (i.e., the ISM, sailcloth, telemetry cans, telemetry wires, power leads, and sensors) for various handler designs, deploy and retrieve speeds from 25 to 400 feet/minute, and inboard and outboard tension loads from 50 to 1000 pounds force.

2. Computation of the deformation, displacement, and rotation time history for the cases in item 1 for all components in the model.

3. The following handler components shall be able to be incorporated in the model: dual capstan, single capstan, pinch rollers, rollers, stowage drum, guide tube with straight and bent sections up to 90 degrees, and linear traction devices. For all of these handler components the geometry (such as multiple grooves in the capstan drums and roller profile), mass, inertia, stiffness, friction properties versus slip rate between the individual handler components and array, and the bearing friction for rotating components such as rollers shall be able to be varied in the model for all cases in item 1.

4. For all handler and array components linear elastic, hyperelastic, or plasticity material models shall be able to be used for all cases in item 1.

5. A fluid cavity shall be able to be defined in the array hose such that the pressure exerted by a fluid (compressible or incompressible) on the cavity boundary and the fluid mass are included in the model. The fluid cavity shall be able to be "inflated" by adding fluid to the cavity which would increase the fluid cavity pressure and then "sealed" simulating that fluid is no longer moving in or out of the cavity. Subsequent deformation of the cavity boundary could then cause a change in the cavity volume or pressure. The fluid cavity pressure and volume time history shall be output from the model for all cases in item 1.

6.3 Challenge Problems

The two Challenge problems listed in this section focus on the modeling of hydrodynamic array streaming conditions with cylindrical turbulent boundary layer flow-induced stresses at high Reynolds numbers. The modeling of array handler-induced stresses must be addressed by proposers in the areas of (1) array hydrodynamic forcing modeling and (2) handler forcing modeling —both being key components of towed array system reliability.

A. Challenge Problem:

Flow Induced Vibration and Fatigue of a Towed Array During Steady Tow

Background Turbulent boundary layer wall pressure fluctuations are a source of vibration and fatigue in towed array internal components. The wall pressure field generated by the non-acoustic, turbulent velocity fluctuations in the boundary layer is transmitted across the array hose wall and fill fluid to the internal array components. Under normal operating conditions a fully developed cylindrical turbulent boundary layer exists over the entire array. During straight, steady-state tows, this wall pressure field is the dominant source of excitation. During maneuvers, secondary cross-flows are generated, leading to increased levels of excitation. However, the complexities of this situation will be excluded from this challenge problem.

Problem Outline A hose wall is excited by a fully developed zero pressure gradient equilibrium turbulent boundary layer at moderate to high Reynolds numbers as shown in figure 2. Either flat-plate geometry or cylindrical symmetry is acceptable. The material can be modeled as a stiff plate, flexible plate, or anisotropic material with internal strength members. All necessary boundary layer parameters will be provided. For flat plate geometry, it is suggested that the wall pressure spectrum is modeled with the Chase (1987) model.1 This model could be modified for the cylindrical case.

Modeling Stage #1: Rigid Plate

Figure 2. Rigid Plate Case.

Apply a forcing function to a classical flat-plate problem, where the forcing function adequately represents convected turbulent wall pressure fluctuations at high Reynolds numbers (1x104 < Rθ < 1x106). Apply simply supported boundary conditions. The problem may be formulated in the space-time domain or wavenumber-frequency domain.

Chase, D.M., 1987, "The Character of the Turbulent Wall Pressure Spectrum at Subconvective Wavenumbers and a Suggested Comprehensive Model," Journal of Sound and Vibration, Vol. 112 No.1, pp. 125-147.

Modeling Stage #2: Flexible Plate

Figure 3. Soft Elastic Plate Case.

Apply a forcing function to a classical flat-plate problem, with a very soft elastic structure (urethane or similar material) as shown in figure 3. The forcing function should adequately represent turbulent wall pressure fluctuations at moderate to high Reynolds numbers (1 x 104 < Rθ < 1 x 106). Apply simply supported boundary conditions. The problem may be formulated in the space-time domain or wavenumber-frequency domain.

Modeling Stage #3: Anisotropic Plate

Figure 4. Anisotropic Soft Elastic Plate Case.

Apply a forcing function to a classical flat-plate problem, with a very soft elastic structure (urethane or similar material) and anisotropy introduced by internal strength members as shown in figure 4. The forcing function should adequately represent turbulent wall pressure fluctuations at moderate to high Reynolds numbers (1 x 104 < Rθ < 1 x 106). Use simply supported boundary conditions. Problem may be formulated in the space-time domain or wavenumber-frequency domain.

Modeling Stage #4:

Full Cylindrical Anisotropic Geometry

Figure 5. Cylindrical Anisotropic Case.

Apply a forcing function to a cylindrical geometry problem with a rigid, flexible, or anisotropic hose wall as shown in figure 5. The forcing function should adequately represent cylindrical turbulent boundary layer wall pressure fluctuations at high Reynolds numbers (1x104 < Rθ < 1x106). Use simply supported boundary conditions. The tension in the hose wall will be included as a parameter.

B. Challenge Problem:

Towed Array Handler Modeling

Primary Objective Build a design tool to accurately assess the loads imparted on an array by the complete handling system in order to provide input for future array and handler improvements. This tool will allow a towed array and handling system designer to:

a) Quickly assess the change in array stress due to handling system or array design changes.

b) Reduce the number of required build-test-build cycles by eliminating design flaws earlier in the design process.

c) Allow a more precise examination of a single design change at a time due to the repeatability of the tool.

Knowledge Gaps The existing handler model used at NUWC simulates handling of the handling system measurement system (HSMS). The HSMS can be used to qualitatively examine handler loads but it cannot be used to understand how loads are imparted on internal array components.

Challenge Problem Outline The goal of this challenge problem is to evaluate the internal stresses imparted on a cylindrical array being pulled through a series of rollers. Data have been previously collected that agree with existing validated models for comparison. Prediction of the load transfer from the handler to internal array components has not been demonstrated to date.

An assembly defined by rollers and capstans representative of a towed array handler is shown notionally in figure 6. The external and internal stresses in a fluid filled hose of a given diameter, which is moved through the assembly, will be determined. The following parameters are provided as guidance:

• Speed: Deployment/Retrieval rates up to 200 feet per minute.

• Tension: Outboard/Stowage Drum loads in the range of 150-500 pounds.

6.4 Program Plan

The three (3) planned phases, Phase I (Base), Phase II (Option I), and Phase III (Option II), are covered by this BAA, and the objectives for each phase are described below. White papers are being requested at this time with full technical and cost proposals for all three (3) phases to follow based on a down select. Full proposals are expected to address all areas in Section 6 above, however ONR reserves the right to award niche proposals. Decisions for continuation to Phase II and Phase III will be based on the degree to which Phase I results meet key objective metrics as described in the following section below and the proposed path to achieve objective metrics.

Phase I Base (15 months):

Phase I has a 15- month period of performance that must be capable of meeting at a minimum one or more of the listed objectives as well as addressing the solution to one or more challenge problems based on the area(s) being proposed.

Phase I efforts shall include but are not limited to the following key areas: array hydrodynamic forcing modeling, handler forcing modeling, constitutive component/material modeling (evaluating array material response including viscoelastic effects, stress relaxation, thermal effects, and fatigue), sensor concepts for model validation, component modules for laboratory model verification, experimentation inputs to guide/validate modeling efforts, and reliability modeling of complex systems. These models should have the ability to accept inputs in the form of measured quantities obtained from tow tests of experimental arrays.

Phase I Objectives:

11. Other Information -

Work funded under a BAA may include basic research, applied research and some advanced technology development (ATD). With regard to any restrictions on the conduct or outcome of work funded under this BAA, ONR will follow the guidance on and definition of "contracted fundamental research" as provided in the Under Secretary of Defense (Acquisition, Technology and Logistics) Memorandum of 24 May 2010. As defined therein the definition of "contracted fundamental research", in a DoD contractual context, includes [research performed under] grants and contracts that are (a) funded by Research, Development, Test, and Evaluation Budget Activity 1 (Basic Research), whether performed by universities or industry or (b) funded by Budget Activity 2 (Applied Research) and performed on campus at a university. The research shall not be considered fundamental in those rare and exceptional circumstances where the applied research effort presents a high likelihood of disclosing performance characteristics of military systems or manufacturing technologies that are unique and critical to defense, and where agreement on restrictions have been recorded in the contract or grant.

Pursuant to DoD policy, research performed under grants and contracts that are a) funded by Budget Category 6.2 (Applied Research) and NOT performed on-campus at a university or b) funded by Budget Category 6.3 (Advanced Research) does not meet the definition of "contracted http://www.onr.navy.mil/Contracts-Grants/submit-proposal/contracts-proposal/contract-model-awards.aspx http://www.onr.navy.mil/Contracts-Grants/submit-proposal/contracts-proposal/contract-model-awards.aspx fundamental research." In conformance with the USD(AT&L) guidance and National Security Decision Direction 189, ONR will place no restriction on the conduct or reporting of unclassified "contracted fundamental research," except as otherwise required by statute, regulation or Executive Order. For certain research projects, it may be possible that although the research being performed by the prime contractor is restricted research, a subcontractor may be conducting "contracted fundamental research." In those cases, it is the prime contractor's responsibility in the proposal to identify and describe the subcontracted unclassified research and include a statement confirming that the work has been scoped, negotiated, and determined to be fundamental research according to the prime contractor and research performer.

Normally, fundamental research is awarded under grants with universities and under contracts with industry. ATD is normally awarded under contracts and may require restrictions during the conduct of the research and DoD pre-publication review of research results due to subject matter sensitivity.

Regarding this BAA, the Research and Development efforts to be funded consists of applied research and advanced technology development. Therefore, the funds available to support awards are Budget Activities 2 and 3.

FAR Part 35 restricts the use of Broad Agency Announcements (BAAs), such as this, to the acquisition of basic and applied research and that portion of advanced technology development not related to the development of a specific system or hardware procurement. Contracts and grants and other assistance agreements made under BAAs are for scientific study and experimentation directed towards advancing the state of the art and increasing knowledge or understanding.

THIS ANNOUNCEMENT IS NOT FOR THE ACQUISITION OF TECHNICAL,

ENGINEERING AND OTHER TYPES OF SUPPORT SERVICES.

II. AWARD INFORMATION

1. Amount and Period of Performance-

ONR anticipates that more than one contract award will result from this BAA. ONR is looking for best value with regards to this research. A total of approximately $10M is anticipated to be available over the 4 year span (FY13-16); however the overall period of performance can potentially span a total of 5 years (FY13-17) to allow for delays and/or additional testing/tasks.

Although the amount of funds and period of performance for each proposal will vary depending on the technical approach to be pursued by the proposer, it is expected each proposal will be structured according to the Research Opportunity Description as stated above. (See Section 6.4, Program Plan, for period of performance)

Approximately $2.5M is available for Phase I (Base) awards.

ONR expects to make Phase II (Option I) awards to a subset of Phase I performer(s) whose products have met the key objectives and expectations described in this BAA. Approximately

$4M is available for Phase II awards; however if sufficient funds are not available to fund continued work by all performer(s), then ONR will exercise Option I only for the Phase I performer(s) that have best met or exceeded the expectations and objectives and have the best likelihood to meet the overall objectives described in the BAA.

ONR expects to make Phase III (Option II) awards to a subset of Phase II performer(s) whose products have met the key objectives and expectations described in this BAA. Approximately $3M is available for Phase III awards; however if sufficient funds are not available to fund continued work by all performer(s), then ONR will exercise Option II only for performer(s) that have best met or exceeded the expectations and objectives and have the best likelihood to meet the overall objectives described in the BAA.

2. Production and Testing of Prototypes-

In the case of funded proposals for the production and testing of prototypes, ONR may during the contract period add a contract line item or contract option for the provision of advanced component development or for the delivery of additional prototype units.

Due to the uniquely governmental position of the Naval Undersea Warfare Center (NUWC) with regard to roles and responsibilities in this towed array system area, NUWC, as part of the core team, will perform the Technical Design Agent (TDA) function in order to help guide, structure, develop, assist, and evaluate each of the FNC-awarded proposal efforts throughout the ONR FNC in a fair and equal manner such that NUWC's expertise in this area is made available to all teams that are awarded a contract.

It is expected that throughout the course of the FNC the governmental role will become more substantive as the FNC enters Phase 2 and Phase 3, as critical testing and at sea experiments are conducted as the FNC product gets closer to transition to acquisition.

This BAA topic covers export controlled technologies. Research in these areas is limited to "U.S.

persons" as defined in the International Traffic in Arms Regulation (ITAR) - 22 CFR § 1201.1 et seq. Additionally, since access to US Navy and other access controlled research facilities will be required, All Key Personnel for each proposer must be United States citizens.

IV. APPLICATION AND SUBMISSION INFORMATION

1. Application and Submission Process - White Papers, Oral Presentations, and Full Proposals

White Papers: The due date and time for receipt of white papers is 2:00PM (Eastern Daylight Time) on 16 August 2012. It is anticipated that white paper feedback will be provided by 17 September 2012. As soon as the final white paper review is completed, the proposers will be notified via email regarding whether their paper presents an approach or concept judged to be “of particular value” to the Navy. Only those proposers whose white papers are determined to be “of particular value” to the Navy are eligible to submit a full proposal or be further considered for an award.

White papers shall be mailed or hand delivered to the technical point of contact listed above in Section 1.7. If hand delivered, building security will contact the Technical Point of Contact (or Tracie Simmons at 703-696-7827) if the Technical Point of Contact is not available to receive the white paper in person. ONR accepts deliveries during normal business hours Monday through Friday, 8:00AM to 5:00PM. White papers received after the published due date and time will not be considered for funding.

Oral Presentations: ONR reserves the right to request that the Principal Investigators (PIs) of white papers determined to be “of particular value” to the Navy provide expanded presentations of their selected white papers. The purpose of the oral presentations is to provide additional information and address how the proposed technology will affect military applications. The time, location, and briefing format of the oral presentations, if requested, will be provided at a later date via email notification. Based on oral presentations received, the Navy will provide additional feedback to proposers, including whether the concept or approach presented remains of particular value to the Navy. Those oral presentations judged at this time to not be of particular value to the

Navy shall be ineligible to submit a full proposal under the BAA.

Full Proposals: The due date and time for receipt of full proposals is 2:00PM (Eastern Daylight Time) on 17 October 2012. It is anticipated that full proposal feedback will be provided by 19 November 2012.
