The most feasible configuration for automatic gust-alleviation system is investigated. In the system considered, inertial sensors and feedback devices are utilized and both wing-flaps and elevators are operated to reduce the gust-induced airplane motions. Three possible configurations of such a system are proposed: linkage control, noninteracting control and split-control (Figs. 1, 3 and 5, respectively). On the other hand, CHANG's frequency-domain theory is applied to obtain an optimal control system which minimizes the gustresponse according to some criterion. Calculations of the alleviation capability of each system are carried out on an example airplane in order to establish numerical evaluations of relative merits of them. Among the three systems proposed, the split-control system is simplest in the mechanization and quite close to the optimal system in the alleviation capability. Thus, it is concluded that the split-control system is most preferable for practical inclusion in the future airplane.
