Determination of take-off constraints for the aerospace vehicle

This paper studies the conditions of the successful takeoff and climbing of the aerospace vehicle. By analyzing the longitudinal kinematics model and dynamic model of the vehicle, the take-off constraints determined by integrating with the lift-drag ratio, thrust-to-weight ratio, flight speed and take-off weight. Moreover, the algebraic form of the maximum take-off weight is also derived to ensure that the aircraft can successfully take off under a fixed configuration. Finally, the simulation results verify the effectiveness of the proposed methods.
