Improving the dynamic response of airplanes by means of electric equipment

This paper begins with an elementary discussion of the mechanics of airplane flight and control. Following this discussion electrical methods for improving the transient response of an airplane in the yawing and pitching modes are outlined and illustrated by two examples. The paper is concluded by a brief discussion of a method by which an airplane cable control system can be replaced by an electric servomechanism. Results of analyses using differential equations and Nyquist plots are discussed and compared with results obtained on an analogue computer.
