Vehicle Systems & Control Laboratory

Texas A&M University College of Engineering

Extra 300 Hingeless Control UAS

Under sponsorship of an STTR Phase I from AFRL through Aeroprobe Corporation, our team has worked for several years in developing hinge-less flight control technologies, and we first expanded the flight envelop to angles-of-attack as high as 25 degrees by embedding Synthetic Jet Actuators (SJA) close to the leading edge of the wing in order to manipulate/eliminate the size of the separation over the wing. The control is achieved through oscillatory blowing and suction along a slot positioned close to the leading edge and parallel to it.  12 flights during 2009.
