A copy of this provision may be obtained from the contracting point of contact. There will be no other solicitation issued in regard to this requirement. Offerors should be alert for any PRDA amendments that may be published.

This guide was specifically designed to assist offerors in understanding the PRDA/BAA proposal process. This PRDA may be amended to allow for subsequent submission of proposal dates. B-- REQUIREMENTS: (1) Technical Description: Multidisciplinary Design Optimization (MDO) is an emerging technology which holds promise to dramatically improve the aerospace vehicle design process. Through integrating air vehicle structure, aerodynamics and flight control system models, automated design trade-off studies can be performed which enable synergistic design concepts to emerge. MDO has the potential to reduce design time, while generating superior designs. Current Air Force MDO technology includes the Automated STRuctural Optimization System (ASTROS), a FORTRAN-based computer code which includes modeling of air vehicle structure and aerodynamics. ASTROS is, in essence, a combination of a Finite Element Analysis (FEA) code similar to NASTRAN, a set of mathematical optimization algorithms (including Fully Stressed Design and mathematical programming), and a suite of linear panel method aerodynamics solvers (including USSAERO for subsonic/supersonic steady aerodynamics, Doublet-Lattice for subsonic unsteady aerodynamics, and Constant Pressure Method (CPM) for supersonic unsteady aerodynamics). ASTROS has been developed and refined over the last ten years, and the code is now in use at approximately seventy industry, government and university locations. During the past few years, it has become apparent to ASTROS users and developers that the steady aerodynamics and maneuver trim capability in ASTROS are not adequate. Users have had difficulty producing reliable, high-quality airloads over a subsonic and supersonic flight regime for complex aerodynamic planforms across the design envelope. The current steady aerodynamics solver, USSAERO, was chosen due to its ability to treat both subsonic and supersonic flight. Also, since ASTROS is an iterative structural optimization routine, the aerodynamics solver has been limited to a linear method so that it could generate a matrix of Aerodynamic Influence Coefficients (AIC matrix) with maximum computational efficiency. The AIC matrix is then used to compute aeroelastic corrections, for all flight conditions, throughout the design optimization process. The steady airloads module is called only once, at the beginning of the ASTROS procedure, and linear aeroelastic corrections are then made as ASTROS performs an iterative optimization sequence on the structural model. USSAERO is a public domain code based on Woodward aerodynamic theory and was first released in the early 1970's. While adequate to model simple aero dynamic planforms, it does not have the ability to accurately model complex geometries, such as blended wing-body configurations, and wings and stabilizers with multiple leading/trailing edge geometry breaks. It also lacks acceptable documentation and configuration control. The purpose of this task is to develop independent, but ASTROS compatible, steady airloads and maneuver trim modules which provide reliable static subsonic and supersonic airloads for complex aerodynamic planforms. ASTROS currently has the capability to perform a trim solution for symmetric and antisymmetric maneuvers, and generates all necessary information for the computation of aeroelastic performance/efficiency constraints such as but not limited to, lift, roll, hinge moment, and control surface effectiveness. The new capability should not only include symmetric and antisymmetric maneuvers, but should also include asymmetric maneuvers as well. In summary, the offeror must address as a minimum three aspects: streamlining and testing the steady aerodynamic modules (sub and super sonic) based on linear methods to account for symmetric, antisymmetric and asymmetric maneuvers in the presence of multiple control surfaces, provide effective leads to by-pass the aerodynamic data computed by the linear methods in ASTROS and bring in data obtained from existing linear aerodynamic codes, wind tunnel testing,or that obtained from the emerging nonlinear flow solvers, make provisions for interfacing (for analysis only) nonlinear flow solvers and finite element models for future integration into design. It is anticipated that the investigation will have three distinct phases (priced separately), as follows: (a) Development of distinct, realistic, quantitative scenarios anticipated during the maneuver loads computations of fighter, bomber and transport aircraft designs found in aerospace companies, (b) Development of a comprehensive steady airloads module and trim module, which provide necessary information for aeroelastic corrections and constraint/sensitivity calculation, and benchmark/document results based on the test cases outlined in (a); (c) Perform a seamless integration of the capability into the ASTROS version 12 system and perform the test problems from (a). It is recommended that a software company be involved in the integration, following all previously determined ASTROS coding procedures, including use of the memory management system and database, separation of all machine dependent and machine independent code, and source code configuration control.
