Research

Smart helicopter and gas turbine blades; active vibration and noise reduction in helicopters, gas turbine and turboprop aircraft; reducing buffeting of vertical fins in fighter aircraft; improved performance of fi ghters at high angles of attack; stability of fly-by-wire aircraft; flutter analysis in the transonic regime.

Application

Reduction of noise and vibration in aircraft brings great improvement in usability and reduced environmental impact in both civilian and military applications. The new technology of active (or smart) structures is very helpful in this effort.
