Subsonic Aerodynamic Characteristics of the T-2C Aircraft with Spanwise Blowing Over the Wing Flaps
Abstract
A wind tunnel study was undertaken to evaluate the concept of blowing spanwise over the wing from the fuselage as a means of increasing lift coefficient of a T-2C aircraft. To optimize gains in lift coefficient, the parameters varied were nozzle position, nozzle angle, flap angle and blowing momentum coefficient. In addition, data were taken to evaluate the effect of spanwise blowing on aileron effectiveness, elevator effectiveness and lateral stability. Gains in lift coefficient over the entire angle of attack range below stall were noted. These gains were most substantial for the slotted flap at its largest deflection of 53 degrees at 43 degrees flap deflection with the flap slot closed. No substantial effect of spanwise blowing on ial effect of spanwise blowing on the stability and control of the aircraft was observed.
