OBJECTIVE AND SCOPE

2.1 Objective:

The primary objective of this work is to provide tactical target vulnerability criteria on specific tactical targets of interest. A parallel objective is to develop assessment methodology and analytical tools, increase experimental test and diagnostic capability.

2.2 Scope:

The vulnerability assessments shall be completed to the extent that they provide probability of desired effect (deny, degrade, delay, destroy) at a reported confidence level. This requires a good understanding and tracking of uncertainties, both systematic and random, over the course of the assessment. All laser interaction parameters shall be reported including spots size dependence and required dwell times. Laser formats shall include both pulsed and continuous wave.

The assessment process shall include six main processes; 1) Target characterization/ exploitation, including coordination with the Intel community 2) Target Failure Mode Analysis (FMA) following a well developed eight –step process to determine target aimpoints 3) Analytical modeling, including various one and two dimensional heat transfer models, Finite Element Analysis (FEA), and energetic material analysis as an example. Analytical modeling provides pre-test predictions and develops vulnerability assessment code 4) Experimental testing following an established approach beginning with coupon level tests and ending with full-scale test demonstrations. Full-scale demonstrations will include both static and dynamic range tests. 5) Post test data assessment and compilation, including development and population of a computer based tactical mission planning folders. 6) The contractor shall also support the annual DEPS symposium, the JTO lethality Technical Area Working Group (TAWG) architecture task IPT as subject matter experts, the AF Precision Engagement product line and the JTO Lethality TAWG tri-service methodology consolidation IPT.

BACKGROUND

The Laser Effects Research Branch (AFRL/DELE) has the charter to evaluate laser effects against potential targets of interest to the DoD. AFRL/DELE has conducted a series of lethality science studies for the JTO lethality technical area working group, (TAWG), established in FY02. The charter of the JTO TAWG is to increase understanding of laser vulnerability on tactical targets and transfer understanding to the warfighter through the JMEMS. Recent work has also begun in support of the AF Precision Engagement product line in the area of area defense.

TECHNICAL REQUIREMENTS

The Contractor shall perform laser effects experiments and vulnerability assessments on tactical targets of interest by applying and implementing innovative models, analyses and experimental techniques.

4.1 Program Plan Development and Coordination

The contractor shall work with the AFRL/DELE Task Order Officer (TOO) to develop a TOO approved program plan that will describe schedule with key milestones, participants, budget requirements, critical paths and deliverables for each task area. The Contractor shall track progress and expenditures against the approved activities in the program plan. The Contractor shall provide weekly status reports summarizing overall progress, accomplishments and issues. The Contractor shall provide monthly status reports with comprehensive, detailed information on funding expenditures, task status, expected near future activities, and any pertinent issues.

The Contractor shall participate in mid-year and end-of-year program reviews with JTO TAWG or Precision Engagement Product Line lead status meetings. The Contractor shall participate in the JTO annually sponsored DEPS lethality conference to communicate results of this task order. (CDRLs A002, A004, A009,)

4.2 Laser Interaction Experimental and Modeling Research:

The contractor shall conduct measurements and develop physics based models and analytical methodologies to further AFRL/DELE’s understanding of the physics of laser material interaction for specific materials used in tactical threat target systems. The target set of interest to the Laser Area Defense Initiative (LADI) includes surface to air missiles, aircraft / UAVs, air to air missiles, and various ground targets. The threat set includes threats to ground based units and inbound out bound aircraft. The current focus of the LADI is on defeat of MANPADs against aircraft. Various foreign MANPADs will be investigated. The vulnerability assessment of the MANPADs will follow a systematic approach of increasing complexity and fidelity. Two parallel paths are expected for the approach one for experimental testing and the other for model development. The modeling path shall include a detailed threat target failure mode analysis, and pre-test predictions for each level of testing. Newly developed and innovative analytical physics based models will be utilized. The testing path shall include all levels of test measurements required from material properties characterization, 1-D thermal transport measurements, complex target geometry one and two dimensional laser interaction tests, structural response component tests, energetic material response tests, and full-scale test demonstrations. Special test apparatus and diagnostics shall be developed when required. All experimental data shall have an uncertainty analysis associated with it. All experimental technique and procedures shall follow an establish methodology approved by AFRL and based on JTO Lethality TAWG standards document. (CDRLs A001, A002, A004, A009, A010, A011)

4.3 Target Vulnerability Assessment, Laser Weapon System Lethality Assessments:

Upon completion of the coupon and component testing results shall be used to formulate vulnerability criteria and product lethality assessments for specific laser platforms both airborne and ground. Examples of laser platforms of interest to the LADI are the Advanced Tactical Laser (ATL) concept and the Tactical Relay Mirror System (TRMS). Laser Vulnerability assessments shall be used to perform Military Utility Studies (MUS) and capability based assessments for similar laser platforms. Vulnerability assessments may also be used to completed risk reduction for range demonstration tests such as an Advanced Concept Test Demonstrations (ACTD). Static and dynamic laser range tests are anticipated for the counter MANPAD work under the Laser Area Defense Initiative.

The contractor shall generate vulnerability assessments based on the results of testing and modeling. The assessment shall include three main components, target aimpoint accessibility, aimpoint susceptibility to laser effect, and laser platform feasibility to deliver required irradiance. The final assessment shall utilize test results incorporated into developed assessment models providing probability of effect at confidence over a range of engagement conditions.

The contractor shall further develop and populate the Tactical Mission Planning Folders (TMPF). The TMPF concept is a computer based compilation of threat target characteristics, specifications, country specific proliferation information, and laser vulnerability assessment. The goal is to locate the TMPF on the SIPRNET for dissemination and document control. The contractor shall develop user interface software to access the existing database software.

A primary goal in completing vulnerability assessments is to provide the war fighter laser effects criteria via the Joint Munitions Effectiveness Manual (JMEM) process. The contractor shall work along side AFRL as a member of the JMEM/FX laser vulnerability working group and the JTO Lethality TAWG to develop the interface between the laser effects community.

4.4 High Energy Laser Modeling, Simulation, and Special Test & Studies.

The goals of this topic are to develop improved numerical modeling and simulation capabilities for laser effects on threat systems. Tools and code developed under this task area shall be utilized during the vulnerability assessment processes. Five main areas of model development are expected;

1) The Contractor shall further develop Heat transfer models to take into account complex geometries including stacked materials, air gaps, temperature dependent materials properties, spot size dependence. The heat transfer codes shall address 1-D, 2-D and 3-D regimes. Physics based models shall be validated with experimental analysis.

2) The Contractor shall work with AFRL to integrate physics based models into existing 3-D shotline models. AFRL has been working with other services to establish a common set of vulnerability assessment tools. A number of 3-D shotline models have been developed for kinetic kill applications among the three services. The Contractor shall generate a working plan to integrate existing AFRL physics code into these 3-D shotline models. The goal of this effort is to produce robust shotline analysis linked to validated physics models including uncertainty analysis, tracking and reporting.

3) The Contractor shall further develop a 3-D Bayesian probabilistic vulnerability assessment code. Over the years AFRL has employed the SABERLITE 3-D code. This code has been employed to generate probability of kill for simple geometry targets. The goal is to develop a similar code for more complex target geometries.

4) The Contractor shall develop models for laser interaction with targets containing energetic materials including propellants and explosives. The goal is to develop a complex kinetic model that incorporates physical realism of energetic materials at high heating rates.

5) The contractor shall work with existing “Flight out models” to model the effects of laser damage to specific MANPADs and other missile systems.

All models developed under this task shall be validated with lethality demonstrations and linked to traceable physics based models developed in other task areas.
