The main objective of this program was to acquire fundamental understanding of two aerodynamic effects induced by vortices shed by blades of aircraft gas turbines: a) the instantaneous separation of total temperature and pressure around vortices in the wake shed and its time averaged effect; and b) the issue of over 100% efficiency measured near the hub section of an advanced turbofan design of the Air Force Aeropropulsion Laboratory. Through the combination of experimental and theoretical investigations, the mechanisms of the two phenomena have been identified.
