Vertical nose strake for aircraft stability and control

摘要

A pivotal strake located at the nose section of an aircraft forebody. The strake pivots about an axis that is essentially perpendicular to the surface of the nose section. Rotation of the strake will influence the forebody vortices to create a resulting yawing moment on the aircraft. The rotating strake can be used to provide directional control of an aircraft, even at high angles of attack.
