Brian P. Danowsky

Principal Research Engineer

B.S., Aerospace Engineering, Iowa State University, 2002
M.S., Aerospace Engineering, Iowa State University, 2004

Mr. Danowsky joined STI in January of 2007. His main areas of expertise at STI are dynamic modeling and simulation of air vehicles, flight control and guidance systems, robust stability and control, aeroelasticity, aeroservoelasticity and aerodynamic parameter estimation. Flight vehicles of study at STI have consisted of high altitude lighter-than-air vehicles as well as high speed fighter aircraft. Mr. Danowsky is currently and has been the principal investigator for numerous government programs in the areas of aeroelasticity and aeroservoelasticity for NASA, the US Air Force and the US Navy.

Research objectives for these programs consist of incorporating active feedback control into very high fidelity coupled computational fluid dynamic and computational structural dynamic models, reduced order modeling capability, aeroelastic uncertainty analysis, adaptive aeroservoelastic suppression, nonlinear aeroservoelastic free-play analysis, and buffet load measurement. Mr. Danowsky is a Senior Member of the American Institute of Aeronautics and Astronautics (AIAA) and is a member of the AIAA Atmospheric Flight Mechanics Technical Committee. He is also a member of the Tau Beta Pi and Sigma Gamma Tau national honor societies.
