The performance, durability, observability, life cycle cost and survivability of these air vehicles is highly dependent on the prediction of aeroelastic effects. Also, as future designs become more optimized the need for accurate aeroelastic analysis will become essential to support and validate design efforts. New technology is needed to integrate state-of-the-art Computational Fluid Dynamic (CFD), Computational Structural Dynamic (CSD), and 3D Design Optimization (3DDO) methods into an effective, timely process that can impact modern air vehicle acquisition, design, and modification strategies. Navier-Stokes CFD and Finite Element Model (FEM) CSD methods have become more tractable in appliction to current design problems and critical flight conditions. The procedure sought shall use workstation graphics and high-speed computational techniques, such as but not limited to, parallelization on shared or distributed architectures, to solve static and dynamic aeroelastic problems from simple untrimmed shapes up to complete air vehicle configurations in trimmed flight. An open data structure is key to the success of this effort as this product will be an interface tool for a broad range of computational methods and industry applications software. To increase the utility of this tool, factors such as inertial point loads, control surface deflection, vertical stabilizer loads, and inlet and exhaust nozzle flow field/structural interaction shall be allowed for. The proposed software would be modular, hierarchical, and versatile. The contractor shall: (a) develop or select, with Air Force approval, a process or processes for aero-structural analysis of air vehicles in all practical (Mach .01 to 10) flight regimes, (b) incorporate multiple levels of physical modeling fidelity up to and including accurate viscous and compressibility effects as well as complex structural configurations, (c) implement accurate interpolation of data between aerodynamic and structural surface representations (this will be key in maintaining overall fidelity and consistency for this code), (d) consider a wide variety of scientific computational data formats as inputs and output that would facilitate Multi-Disciplinary Design, such as: PLOT3D, GRIDGEN, IGES, APGS PATRAN Neutral, MSC NASTRAN, ASTROS, and others, (e) structure the software to be portable on UNIX based machines so that it can run both interactively and non-interactively when necessary, (f) Validate the code for static and dynamic conditions by quantitative comparison with test data, analyze interpolation accuracy, and demonstrate functionality, all for a wing/body and a complete air vehicle. The air vehicle configuration shall include: fuselage, wing, wing flaps and/or ailerons, horizontal and vertical stabilizers, and wing point loads (inertial), (g) Include accurate grid deformation techniques for both static and dynamic solutions, and (h) Consider inclusion of fully associative geometry's for growth into a fully integrated design environment. (2) Deliverable Items: (1) The contractor shall deliver all software needed to run the complete aero-strutural package. This includes software developed by the contractor and any required unique or special purpose hardware or software that WL/FIM does not already possess. It is anticipated that all source code and required library routines will be the property of the United States Air Force and not subject to any licensing agreements. WL/FIM's current hardware consists of UNIX based Silicon Graphics Iris Workstations and IBM RS-6000 workstations networked together and running Parallel Virtual Machine (PVM). (2) Deliverable Items: The following deliverable data items shall be proposed: (a) Status Report, DI-MGMT-80368/T, bi-monthly, (b) Funds and Man-hour Expenditure Report, DI-FNCL-80331/T, monthly, (c) Project Planning Chart, DI-MGMT-80507A/T, monthly, (d) Presentation Material, DI-ADMN- 81373/T, as required, (e) Scientific and Technical Reports, Contractor Billing Voucher, DI-MISC-80711/T, monthly, (f) Scientific and Technical Reports, DI-MISC-80711/T, (Draft and Reproducible, Interim and Final), (g) Test Plan, DI-NDTI-80808/T, Full-scale evaluation, (h) Engineering Drawings, DI-DRPR-80651/T, and (i) Innovations Report, DI-MISC-80406. A kick-off meeting will be held at the contractor's facility within 60 days after contract start. The contractor will further be required to conduct program reviews quarterly and at the end of each task alternating between Wright Patterson AFB and the contractor's facility. (3) Security Requirements: The classification level of work performed under this contract shall be limited to UNCLASSIFIED. (4) Other Special Requirements: Equipment/technical data generated or delivered in performance of this contract is controlled by the International Traffic in Arms Regulations (ITAR). C--ADDITIONAL INFORMATION: (1) Anticipated Period of Performance: The total length of the technical effort is estimated to be 36 months, but the contractor may propose an alternate schedule to demonstrate the technology. The contractor shall also provide for an additional 3 months for processing/completion of the final report. The proposed program schedule could be different from what is anticipated by the Government. (2) Expected Award Date: Third Quarter FY96. (3) Government Estimate: The Government anticipates a funding breakout by fiscal year as follows: FY96-$50K, FY97-$300K, FY98-$400K, and FY99-$400K for a total of $1,150K. The Government funding profile is an estimate only and is no a promise for funding as all funding is subject to change due to Government discretion and availability. (4) Type of Contract: Cost Plus Fixed Fee (CPFF). (5) Government Furnished Property: No government property is anticipated for this contractual program. (6) Base Support: None anticipated. (7) Size Status: For the purpose of this acquisition, the size standard is 1000 employees (SIC 8731). (8) Notice to Foreign-Owned Firms: Such firms are asked to immediately notify the Air Force point of contact cited at the end of this PRDA upon deciding to respond to this announcement. Foreign contractors should be aware that restrictions may apply which could preclude their participation in this acquisition. END OF PART 1. (0313)
