Inlet Multi-Objective Optimization for Air-Breathing Electric Propulsion
摘要
Abstract
The low orbital altitude of the near-Earth satellite makes the satellite have higher detection accuracy.Howev-er,the service life of the satellite is restricted by the drag caused by the satellite not completely leaving the atmosphere.The air-breathing electric propulsion system is used to extend the life of the satellite.The direct simulatiou Monte Carlo(DSMC)calculation method is used to simulate a two-dimensional air-breathing electric propulsion model.The wall im-pact model is set as completely diffuse reflection.On the premise that the inlet diameter of the inlet is maintained at a constant value,the inlet long-to-longitudinal ratio,outlet cone angle,grid length and grid layer number are changed to ex-plore the inlet performance variation rule under the single action of these influencing factors.Under the premise of single in-fluence rule,genetic algorithm is used to carry out multi-objective optimization,and the design parameters of high-perform-ance inlet meeting the design requirements are obtained,and the optimal design method of inlet at typical height is studied.关键词
