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.
The overall goal of the project is to develop reliable reduced order modeling technologies to automatically generate parameter-varying (PV), aeroservoelastic (ASE) reduced-order models (ROMs) for aerostructural sensing and control. In Phase 1, both equation-based and data-driven PV ROM technologies were developed and proof-of-principle was successfully demonstrated. A set of carefully selected ROM algorithms and model coupling schemes were developed in an integrated architecture to generate PV ASE ROMs. Critical evidence was established in NASA relevant case studies that ROMs enable unprecedented speedup and accuracy for aircraft ASE analysis. PV ASE ROMs for X-56A MUTT models in the current mission were developed, which demonstrated >10X reduction in the number of states and precise capture of vehicle dynamics at various flight conditions. In Phase 2, software will be expanded and refined for enhanced performance and functionality. ROM algorithms will be optimized in terms of efficiency for MIMO systems, consistent state representation, PV capabilities in a broad flight envelope. PV structural ROM will also be developed to consider changes in modal parameters at various flight conditions. The strategies for integrating ROMs, sensors and actuators with control design for ASE studies will be tailored to meet various needs in NASA. A modular software environment will be developed with facile interfacing to NASA tools for technology insertion and transition. ROM software will be extensively validated and demonstrated for ASE and flight control analysis of the current X-56A MUTT model, its future release, and other relevant aircrafts.

If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
