Details of the dynamics involved in an aircraft loss of control situation are required to better understand how a system can best regain control without further exacerbating the situation. Enhancements to engine modeling for situations requiring improved engine response during full or partial loss of flight control will also be developed. Successful transition of this foundational research into the national airspace system depends greatly on the ability to verify and validate the novel control and guidance technologies, especially those based on adaptive control. Verification and validation of these technologies will be performed through a combination of analyses, simulation, wind tunnel and flight testing using model-scale and full-scale (manned) test vehicles. The IRAC Project will utilize selected proposals under the NRA to leverage in-house fundamental research with academic institutions, non-profit organizations, and industry partners performing fundamental research to address knowledge and technology gaps.

The following are ROA-2007 NRA awards for the IRAC Project, with the most recent listed first.
