Abstract

A control assembly (50) for deployment of aircraft wing flaps is comprised of an input cam mechanism (54), a feedback cam mechanism (56) and a summing lever member (58) operatively interconnecting the cam mechanisms for mechanically summing independent inputs therefrom to yield a mechanical output signal for actuating flap deployment drives, wherein the input cam mechanism is comprised of a cam (64) rotationally operable in response to a command input signal and a cam follower (68) in mating engagement therewith for cammed movement with rotation thereof to provide a first input signal to the summing lever characteristic of a predetermined flap configuration, the feedback cam mechanism is comprised of a cam (94) rotationally operable in response to movement of the flaps and a cam follower (100) in mating engagement therewith for cammed movement in response to movement of the flaps to provide a second input signal to the summing lever characteristic of the existing flap configuration; and further wherein the summing lever receives the first input signal via a first input leg (160) and the second input signal via a second input leg (162) and provides a mechanical output signal as a su…
