Prediction of Unsteady Transonic Aerodynamics

Completed Technology Project

Project Description

Prediction of Unsteady Transonic Aerodynamics
An accurate prediction of aero-elastic effects depends on an accurate prediction of the unsteady aerodynamic forces. Perhaps the most difficult speed regime is transonic where the motion of the shock wave and its interaction with the boundary layer are dominant factors. In spite of over 40 years research into the computation of unsteady transonic aerodynamics there still appear to be areas where available technology is inadequate. A research axiom is that if a particular viewpoint fails to resolve an issue then the problem should be viewed differently. The research proposed here is to re-examine some issues in unsteady transonic aerodynamics using some recent theoretical developments. All aspects of unsteady transonic flow, including limit cycles and control strategies will be considered. More »
