CFDRC uses model order reduction (MOR) to develop reduced order models (ROMs). CFDRC’s MOR methodology is based on mathematically rigorous approaches (as opposed to empirical, analytical, or hardware-based methods), therefore it can used for real-time simulations on lesser machines without compromising accuracy or resolution. The methodology has been demonstrated and validated for diverse applications include aerospace, missile defense, energy, materials and biomedical.
Reduced states from 180 to 21
"This technology will markedly reduce the development cycles of aerospace vehicles at reduced costs. It is inherently time- and parameter-varying by design to allow more intuitive analysis" - Marty Brenner, Aerospace Engineer at NASA Armstrong Flight Research Center
Aerodynamic ROM and Structural ROM coupled for integrated analysis
