挂弹钩非对称弹射过程调控方法研究

建立采用抛放弹火药燃气作为工作能源的挂弹钩弹射机构的数值计算模型，对抛放弹燃烧，弹射活塞非对称工作，直至推离悬挂物(导弹或炸弹)的整个动态过程进行了模拟计算。分析左右两侧导气孔直径的调整对非对称弹射效果的影响。结果表明，通过调整两侧导气孔直径，可以改变悬挂物弹射离机时的飞行姿态，消除由于不同弹种的质心偏移量所造成的角速度与角位移偏大的弊端。该文所建立的模型为该种弹射装置的自适应控制和优化设计奠定基础。

Control Method for Unsymmetrical Ejection Process of Suspender Ejection Device

A numerical model for suspender ejection device with the powder gas of blank cartridge as driving energy is established. The whole dynamic process from the burning of the blank cartridge and the unsymmetrical motion of the ejection piston, to the complete pushing away of suspender (missile or bomb) is simulated. The influence on the unsymmetrical ejection effect by the adjustment of the left and right gas port diameters is analyzed. It is shown that the flying attitude of the suspender leaving battleplane can be changed by adjusting the gas port diameters of both sides, so as to eliminate the abuse of larger angular velocity and displacement caused by the centroid offset of different suspenders. The model settles a basis for the self-adaptation control and optimum design of such a type of ejection device.
