Popis
Shrnutí:The influence of phase and other constraints on the method of searching for the trajectories of a civil supersonic aircraft that are optimal in terms of fuel consumption is considered. Based on the solutions found by the dynamic programming method, which take into account the numerous conditions that must be satisfied by the flight altitude, pitch angle, normal overload, aircraft speed, engine thrust, etc., it is shown that almost all of these conditions can be ignored during the initial stage of calculations, since these constraints do not affect the optimal solutions. Therefore, one can first apply the maximum principle and use the dynamic programming method only in those cases where a sizeable part of the constraints turns out to be significant.
