Abstract
Abstract The invention is an improved flight control system for aircraft. The improved flight control system mixes or blends several flight control movements into a unified operation. The flight control mixing system of this invention combines the functions of standard ailerons (a roll and lateral control device) with standard flaps (a lift control device) on aircraft into a single control device, referred to herein as flaperons. The improved system can also be used on tailess or flying wing type aircraft to combine the functions of standard ailerons with the elevator functions (a nose up or down pitch control device) into a single control device, referred herein as elevons. The improved system is also applicative to V-tail type aircraft for controlling the elevators in a similar single control operation, herein referred to as ruddervators. The improved flight control mixing system consists of an improved linkage system comprising five major components: a swing arm mounting element affixed to the airframe; a swing arm element for control of concurrent parallel operation of flight control surfaces; a special bell crank-like element capable of two modes of transmission of flight control operations; a bell crank element for transmitting one of the modes of transmission to the special bell crank-like element; and a transfer component to transfer input from the bell crank element to the special bell crank-like element.
