Statement of Objectives TO 0001- Computational Research of Propulsion Components and Systems

(Technical Area 1) 3 Dec 2019

Cleared for Public Release Case Number 88ABW-2020-0603 19 Feb 2020

1.0 Objectives:

This Task Order advances high-speed air breathing engine technology by utilizing computational analysis tools that investigate fundamental phenomena, evaluate prototype and early development concepts, and assess components/engine flowpaths.

2.0 Applicable Documents:

2.1 AFRL ANSI National Information Standards Organization (NISO) – Based Guide to Formatting Technical Reports, dated 2018, or current version

2.2 AFRL/RQH Hypersonic Technology Security Classification Guide – Draft copy available via the Bidders Library

3.0 Tasks Include:

3.1 Suggested Research Topics

Suggested research areas of interest include: 1) predictive and post-test analysis of ground and flight experiments, 2) assessment of unique design concepts aimed at improving performance by modeling inlet, isolator, combustor, nozzle, subsystems, flowpath components, and fully-integrated vehicles, and 3) Modeling of liquid, supercritical, or multiphase flows to simulate injection processes, physical phenomena and kinetics models.

3.2 Predictive & Post-test Analysis

Simulation and analysis will be used as a means of predicting performance or evaluating post-test operation of ground and flight tests of engines, subsystems and components developed by AFRL/RQH researchers or other organizations.

Assessments of unique test approaches or analysis techniques aimed at improving the connection between ground and flight tests are also of interest.

Examples of specific research areas could include predictive evaluations allowing acceptance testing of flight engines in ground facilities, evaluation of Government or industry developed components in ground testing facilities in preparation for integration into flight engines, simulation of initial vehicle flight test trajectories, and modeling of sub-1X to 10X scaled high speed air breathing combustion engines and concepts for ground and flight tests.

3.3 Assessment of Design Concepts

Assessment of unique design concepts aimed at improving performance by modeling inlet, isolator, combustor, nozzle, subsystems, flowpath components, and fully-integrated vehicles includes but is not limited to: investigating variable geometry inlets, inflow distortion effects, cold start ignition concepts, boundary layer bleed or unique injection/flameholding techniques.

3.4 Modeling of Liquid & Supercritical/Multiphase Flows

Research shall be conducted to increase the understanding of fuel injection for high-speed air breathing propulsion systems. This includes but is not limited to modeling fuel injection to include liquid, supercritical, and/or multiphase fluids, and the development of combustion kinetics models. Improved understanding of injection techniques enabling successful ignition is also a priority. Specific efforts of interest to the Government might include simulations using liquid and/or aerated liquid fuels and evaluation of liquid fuel kinetics models (JP-10, RP2, JP- 8, etc.) using experimental results from the Air Force or other partners over a wide range of operational conditions. Also included are assessments or refinements of fuel injectors or techniques during all phases of flight conditions by applying modeling advancements and simulation methods.

3.5 Code Refinement and Application of Advanced Techniques

In addition to the three research areas of interest, the continued development, refinement and application of LES and RANS (including hybrids) and other advanced modeling techniques are priorities. Assessments and, when possible, improvements, shall be made to increase the fidelity or accuracy of models.

Areas of improvement may include turbulence modeling, turbulent mixing, heat transfer (especially radiation), and chemical kinetics of liquid and gaseous fuels.

3.6 Period of Performance: 27 months, 24 months for the technical effort plus three months for reporting.

3.7 Modifications to Existing Government Computational Fluid Dynamics (CFD) Codes:

Planned modifications to existing Government owned CFD codes must be disclosed in the individual Task Order proposal and included in the Task Order SOW; detailed plans on modifications are required after contract award.

3.8 AFMC/AFRL/RQ Mandated Regulations

Compliance with all AFMC/AFRL/RQ information technology and security regulations is required.

4.0 Operations Security (OPSEC):

Operations Security (OPSEC) must be an integral part of our daily activities. As we maintain security on our future technologies that are vital to national interest, we must recognize and prepare for the threat poised against our technology. Department of Defense policies mandate a high degree of security throughout the acquisition process.

However, heightened security awareness and threat-based countermeasures are particularly essential during the research and development phase when our technology is most vulnerable to espionage, sabotage, or exploitation. It is the obligation of each employee or persons involved on this contract be constantly aware of and strictly adhere to security requirements designed to protect sensitive unclassified and other information and resources produced by acquisition, research and development, and technological security efforts outlined in this SOO. The contractor shall ensure employees receive training and follow appropriate Operations Security (OPSEC) measures during the performance of the contract.

5.0 Program and Financial Management:

The contractor shall exercise administration and management functions during the course of this effort such as: scheduling of activities and milestones; describing status;

outlining contractor activity and progress toward accomplishment of objectives;

planning, forecasting, and making recommendations on funding and funding changes.

Additional Information regarding this SOO: Detailed information on requirements for Program Management, Base Support, and Data/Deliverables are available in the BAA.
