Spacecraft Propulsion System Performance Simulations,

Abstract

This article takes the ducting system associated with the propulsion system of a certain spacecraft and sets up a distribution parameter form of mathematical model. Moreover, concentration parameter forms of mathematical model are then set up for such things as valves (illegible), injectors, as well as combustion chambers, and so on. Respective application is made of characteristic linear methods and fourth order Longge--Kuta (phonetic) methods to carry out mathematical simulations on 386 microcomputers. Going through large amounts of simulation calculations, a number of opinions are put forward associated with references that can be supplied.
