6554229, Apr 29, 2003

Filed:

Sep 20, 2000

Appl. No.:

09/581951

Inventors:

Lawrence Y. Lam - Rancho Palos Verdes CA 90275
Michael Lam - Los Altos Hills CA 94024

International Classification:

B64C 906

US Classification:

244217

Abstract:

An aircraft aileron system ( ) is comprised of two panels ( ) located at the rear portion of the wing (W ), in a spanwise direction and aligned with the wings trailing edge. The panels are independently hinged at their leading edges and rotate to make angular deflections with respect to the wing. The upper, aileron panel ( ) is restricted to upward deflection only from its neutral position and in operation is deployed independently as an aileron. The lower, auxiliary flap panel ( ) is capable of both upward and downward deflections from its neutral position, and is deployed independently downward as an auxiliary flap. Both panels are deployed together upwardly only as an aileron. Alternatively, the auxiliary flap panel is capable of downward deployment only, to provide a simpler aileron system. For roll control of an aircraft during cruise, the aileron panel on one side only is deflected up while the aileron panel on the other side remains in its neutral position.

Abstract:

An aircraft aileron system unique in its construction, method of deployment and the functional results obtained, is comprised of two panels located at the rear portion of the wing, in a spanwise direction and aligned with the wing's trailing edge. The panels are independently hinged at their leading edges and rotate to make angular deflections with respect to the wing. The upper, aileron panel is restricted to upward deflection only from its neutral position and in operation is deployed independently as an aileron. The lower, auxiliary flap panel is capable of both upward and downward deflections from its neutral position, and is deployed independently downward as an auxiliary flap. Both panels are deployed together upwardly only as an aileron. Alternatively, the aileron panel may be capable only of upward deployment while the auxiliary flap panel is capable of downward deployment only, to provide a simpler aileron system.
