Abstract

Because the flight performance of aircraft is so dependent on aerodynamic efficiency of elevator, it is very important to improve the flow separation over the control surfaces at high deflection angle in order to keep the aircraft having good flight capability, especially for the modern aircraft with tailless aerodynamic configuration. A new flow control technique to improve the flow separation over the control surface by microblowing at the flow separated position is discussed in this paper. Furthermore, the effect of the various blowing parameters are also investigated in detail, and based on these studies, the parameter similarity about this flow control technique is discussed.
