Abstract:

The effects of the adjustment of control mechanisms coupling factor variations of certain autopilots on the characteristics of the motion of an aircraft, omitting flexibility and compressibility effects, were investigated. The investigations are based on the simple equations of motion of an aircraft. In addition, variations of the motion due to applying more complex equations were investigated. The motions were calculated as responses to a unit step impulse of a yawing moment due to variation in thrust of a side engine or to the occurrence of a crosswind field which decreases a little later, as, e.g., in the case of a horizontal side gust. A distinction is made between suitable and less suitable motions of the aircraft. The settings of the autopilot which have to be provided to obtain suitable motion are determined. Author
