The proposed technology will provide a fast and accurate analysis tool for ASE simulations of aerospace vehicles and aircrafts. NASA applications of the technology include: (1) rapid and computationally affordable analysis for optimal aerodynamic and structural design of aerospace vehicles; (2) development of advanced, reliable ASE control strategies (such as controlled maneuver, and aeroelastic instability control, e.g., buffet, flutter, buzz, and control reversal); and (3) arrangement of test procedures for rational use of instruments and facilities. The success in the proposed research will markedly reduce the development cycles of aerospace vehicles and aircrafts at reduced costs. NASA programs like aerostructures test wing, active AeroElastic Wing (AEW) and active twist rotors, Multi-Use Technology Testbed (MUTT) will also stand to benefit from the technology. The non-NASA markets and customers of the proposed software include various aerospace, aircraft, and watercraft engineering sectors (involving fluid-structure-control interaction). Potential end-users and customers include various government agencies such as US Air Force, Missile Defense Agency (MDA), US Army, Space and Missile Defense Command (SMDC), US Navy, etc. In addition, the proposed technology will also find broad markets in industries such as aircraft and aerospace, automobile, combustion, power, propulsion, chemical processing, and micro-electro-mechanical systems (MEMS). The proposed research would directly contribute to these vital areas by providing a powerful tool to generate fast ROMs, which can be extensively used to (1) analyze the operating processes for fault diagnostics and optimized design (e.g., structure and fatigue analysis, real-time flow control and optimization, hardware-in-loop simulation); and (2) develop advanced strategies for on-line process monitoring and control.
