通过对蒸汽弹射器基本工作原理的了解，运用动力学与热力学知识对其进行分析，考虑风速和开槽汽缸导热及漏气对弹射的影响，在合理的假设前提下利用Matlab/Simulink仿真软件建立出了蒸汽弹射热力学动态仿真模型，并以美国C-13型蒸汽弹射器为对象进行仿真分析，得出弹射过程中舰载机的加速度、速度、位移和储汽筒和汽缸内压力、温度以及漏汽量及耗汽量等参数的变化规律，对进一步了解蒸汽弹射具有一定意义。%The paper using the knowledge of dynamics and thermodynamics and the understanding of the basic prin-ciple of steam catapult, developing an analysis on the steam ejection of carrier-based aircraft, which is considering the thermal conductivity, the wind speed and the cylinder leakage effects on ejection;furthermore, a thermodynamic steam cata-pult out of a dynamic simulation model is established under the reasonable assumptions of the use of Matlab/Simulink simu-lation software. Meanwhile, a simulation analysis on C-13 type steam ejection of America shows that the acceleration, the velocity, the displacement, the steam reservoir, the inner pressure of the cylinder, the temperature, the quantity of the steam leakage and the steam consumption etc. and such kind changing rule of parameters, which are of great significance to have a further understanding of the steam ejection.
