Carrier-Based Aircraft Steam Catapult Control System

摘要

In order to make the carrier-based aircraft take off smoothly, a steam catapult controller is designed in this paper. The thermodynamic model of the capacity selector valve, the steam storage cylinder and the cylinder, and the motion model of the carrier-based aircraft are built. Then the steam catapult controller is designed. Based on the feedback linearization theory, the cylinder system model can be fully linearized to achieve the state of the cylinder decoupling. The influence of various factors such as the change of the thermodynamic state in the steam storage cylinder, the change of the steam flow process, the opening and the circulation characteristics of the launching valve are taken into account. The program is capable of simulating the thermodynamic and kinetic parameters of a series of ejection processes. The simulation results show that the steam catapult controller designed by the feedback linearization method is stable in the process of ejection, so that the carrier-based aircraft can have good tracking ability to the acceleration command.
