This contract was awarded by the National Aeronautics and Space Administration (NASA) Shared Services Center to Research In Flight LLC, a small business organization, under the Small Business Innovation Research (SBIR) program. The contract, valued at $1,000,000.00, is for the development of the FLIGHTSTREAM aerodynamic prediction code, which uses a surface-vorticity approach to enable more robust and computationally efficient modeling of non-linear aerodynamics and flow separation. The focus of this Phase II effort is to expand the capabilities of the FLIGHTSTREAM code, including the implementation of a fluid strain-based separation model, the application of the fast multipole method to improve solver speed and memory usage, and the development of a higher-order vorticity sheet solver to enhance solution fidelity and stability. This work is intended to position FLIGHTSTREAM as a commercially viable, physics-based solution for predicting high-lift aerodynamic performance.
