Based on the analysis of aircraft ejection system, this paper establishes the mathematical model of aircraft ejection system based on the basic assumptions. The mathematical model includes the parameter calculation and device design, both positive and negative. In this paper, the theory and method of steam ejection system design and calculation are studied systematically. Studied the ideal design rules and the ways and methods to realize the ideal design rules. This article through the digital simulation method. The mathematical model has been preliminarily evaluated. The simulation results are close to those reported in foreign countries and can be used as the theoretical basis for the preliminary design and experimental study of the ejection device. With the mathematical simulation of the development of the graphics display simulation software also has good simulation results and practical value.
