航空機の動安定特性と操縦者の動特性

Abstract

Dynamics of pilot was studied quantitatively in relation to the change of dynamic stability characteristics of aircraft. Three pilot conducted bank control on flight simulator which simulate aircraft dynamics with large variety of dutch roll characteristics, and data was acquired. Dynamics of pilot was expressed by the transfer function which include dead time, gain, lead time constant, lag time constant. To determine these parameter, dynamics of pilot was identified by the acquired data using output error model. The dead time of the pilot was thought to be 0.3sec, because of that the error between the actual data of the aileron deflection angle in bank control and the output of the transfer function of pilot is smallest in case of assuming it. It has been understood that flying quality preferred by the pilot corresponds to that the airplane is controlled with the gain of the pilot more than the certain value changing with the flight condition, with the lead time constant of the pilot less than 0.8sec and with the lag time constant of the pilot less than 0.3sec.
