U.S. Patent Specifications

Abstract

Control means for aircraft having a conventional fuselage, a mast carried thereby and sustaining propellers therefor mounted for rotation above the mast comprising the combination of three similar control panels, means radially mounting said panels from the mast in the slipstream of the propellers including axis structures symmetrically disposed about the mast and providing axes on which the panels are mounted for relatively free turning movement and which extend diagonally to the span axes of the panels, and means for positively turning the panels about said axes thereby to produce control moments.
