Influence of the air intake flap opening system when starting ramjet on a vehicle trajectory

Abstract

The paper presents the results of a study concerning impact interaction of air intake flap opening system on the flight dynamics of a high-speed vehicle at the time of ramjet start mode under condition of real atmosphere. The presented dynamic model of the integrated system "Vehi-cle-Ramjet" makes it possible to develop appropriate control law by vehicle in order to minimize perturbations on the flight trajectory for guarantee of the energetically favorable trajectories that is a necessary requirement for the vehicle to achieve the design point of trajectory in the ramjet start mode
