Book Description
Aerodynamic equations for the longitudinal motion of an aircraft with a horizontal tail were developed. In this development emphasis was given on obtaining model structure suitable for model identification from experimental data. The resulting aerodynamic models included unsteady effects in the form of linear indicial functions. These functions represented responses in the lift on the wing and tail alone, and interference between those two lifting surfaces. The effect of the wing on the tail was formulated for two different expressions concerning the downwash angle at the tail. The first expression used the Cowley-Glauert approximation known-as "lag-in-downwash," the second took into account growth of the wing circulation and delay in the development of the lift on the tail. Both approaches were demonstrated in two examples using the geometry of a fighter aircraft and a large transport. It was shown that the differences in the two downwash formulations would increase for an aircraft with long tail arm performing low-speed, rapid maneuvers.Klein, VladislavLangley Research CenterUNSTEADY AERODYNAMICS; AERODYNAMIC CHARACTERISTICS; AERODYNAMIC STABILITY; LONGITUDINAL STABILITY; LIFT; PITCHING MOMENTS; WIND TUNNEL TESTS; BODY-WING AND TAIL CONFIGURATIONS; WINGS; TAIL ASSEMBLIES; DOWNWASH; FIGHTER AIRCRAFT
