The purpose of this paper is to address the problems of Aircraft Engine Technology, Airframe Technology, and Rotorcraft Technology. In addition, several applied problems for domestic industry are also studied using knowledge and experience from Aerospace Sciences. The reduction of aircraft noise is a significant driver in the success of the NASA AST and HSR programs as they attempt to meet stringent international environment regulations on noise for commercial aircraft. In accordance with the project fulfillment under this NASA grant the (Fluid Mechanics and Acoustics Laboratory) FM&AL investigates novel and promising concepts for reduction of noise and improvement of propulsion efficiency in jet exhaust nozzles and fans.
