DEVICE FOR ENHANCING AIRCRAFT STALL AND SPIN CHARACTERISTICS (VERSIONS) Russian patent published in 2007 - IPC B64C5/08

Abstract RU 2297364 C1

FIELD: aircraft control and stability devices.

SUBSTANCE: proposed device is made in form of stall fences mounted on lower surface of wing or on tail section of aircraft symmetrically relative to longitudinal plane of symmetry of aircraft. Stall fences begin at distance not exceeding 2 B and end at distance of 0.3-1.0 B from respective leading edge; their maximum height reaches 0.3 B, where B is aerodynamic chord of wing at area of mounting the stall hence.

EFFECT: facilitated going out of spin.
