Study of a control system to alleviate aircraft response to horizontal and vertical gusts

Abstract

A study is made of the longitudinal response of a STOL airplane equipped with a vanecontrolled gust-alleviation system. Effects of various combinations of design parameters on the responses to horizontal and vertical gusts and to elevator inputs are presented. Almost complete gust alleviation may be obtained with this system when the center of gravity of the STOL airplane is at rearward locations, but pitch stability augmentation is required for satisfactory control characteristics
