SIMPLIFIED FORMS OF PRELIMINARY TRAJECTORY CALCULATION FOR GUN-LAUNCHED VEHICLES

Abstract

An approximate numerical method for calculation of trajectories of hypersonic vehicles is described, with particular reference to gun-launched vehicles. Because of the form of the hypersonic drag coefficient, a relatively simple calculation using functions which depend only on altitude is possible. Reasonable accuracy can be obtained even for computations in which very large calculation intervals are used. The method is particularly suitable for preliminary engineering calculations which do not justify a detailed computer solution, and has the added advantage of giving the analytic forms linking input and output. The technique is shown to be applicable to glide trajectories with and without drag and to rocket powered trajectories as well.
