The Minimum-Time to Turn Problem for a High Thrust to Weight Ratio Aircraft

摘要

Optimal control theory is used to determine open-loop control laws for thrust, coefficient of lift, and bank angle for minimum time maneuvers for high thrust-to-weight ratio aircraft. In obtaining these control laws, an aircraft mathematical model is used which includes constraints on thrust, coefficient of lift, and on the aircraft load factor. Numerical results are discussed for two maneuver problems which are stated as minimum-time turns from specified initial conditions to the following terminal conditions: only heading angle specified, and heading angle and velocity specified.
