- Description
- The National Aeronautics and Space Administration (NASA) High Altitude Long Endurance (HALE) Project at Dryden Flight Research Center (DFRC) has a need for a Contractor to develop specific models for HALE class of vehicles simulator. NASA/DFRC intends to procure these services from University of Michigan, Prof. Carlos Cesnik, Aerospace Engineering Department, 50 Thompson Street, Ann Arbor, Michigan 48109-1340. Carlos E. Cesnik is an expert in the areas of active nonlinear aeroelasticity, structural mechanics and smart structures and extensive experience infinite element modeling, and structural and design optimization. Mr. Cesnik developed a strain-based geometrically nonlinear beam dynamics analysis which will be utilized to accomplish this work. Development to be performed is to create a coupled 6-DOF vehicle simulation with the nonlinear strain-based structural formulation for high-aspect ratio lifting surfaces. The resulting tool will be integrated in DFRC simulation environment for future HALE class of Vehicles. Equations of motion modules developed will build on the PI's previously developed Matlab-based computer code Nonlinear Aeroelastic Simulation Toolbox (NAST), and made compatible with DFRC simulation modules and structure. The simulation will contain different sources of nonlinearities that are computationally time-consuming. Classification of the different nonlinearities for a given aircraft configuration will allow the elimination of time-consuming calculation of nonlinear terms that do not significantly affect the vehicle's response. Two main levels of simulation will be pursued: batch and real-time simulations. A low-order strain-based nonlinear structural analysis coupled with unsteady potential flow aerodynamics form the basis for the aeroelastic model, and needs to account for the interactions between wakes of different lifting surfaces, or interference between fuselage and wings, for a representative nonlinear structural flexibility model. Report detailing all equations, assumptions, methods used to arrive at the conclusions drawn on all work. (1 job, 12 Months after contract award) Software models in Matlab format (1 job, 12 Months after contract award) The Government intends to acquire a commercial item using FAR Part 12 or 13. Interested organizations may submit their capabilities and qualifications to perform the effort in writing to the identified point of contact not later than 3:30 p.m. local time on ___8/1/05________. Such capabilities/qualifications will be evaluated solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. A determination by the Government not to compete this proposed effort on a full and open competition basis, based upon responses to this notice, is solely within the discretion of the government. Oral communications are not acceptable in response to this notice. All responsible sources may submit an offer which shall be considered by the agency. An Ombudsman has been appointed.
