Abstract:
A method of estimating the airborne path during take-off is proposed, based on the assumption that the aircraft is rotated at a constant rate of pitch from the moment of lift-off to the point at which it attains a steady climb path. The justification for this assumption is discussed. A simplified analysis, using small perturbation equations of motion, has been developed for initial project studies. Examples of the method applied to a slender wing transport aircraft, and a lightly loaded STOL aircraft are given, and the factors affecting the value of rate of pitch used are discussed.
