基于量子理论的无工质微波推进性能计算分析

The Performance Analysis of Microwave Thrust without Propellant Based on the Quantum Theory

无工质微波推进是一种新概念推进装置,具有推力大、结构简单、性能可靠的优点,可广泛应用于空间飞行器。为了给以后的设计研究奠定基础,本文基于量子理论,对无工质微波推力器腔体内的微波电磁场进行量子化处理,推导出推力的理论计算公式,使用有限元分析软件计算出不同模态的腔体固有品质因子Q值,计算出不同模态下的推力值。计算结果表明TE012模态下的Q值最高达79523,推力修正值最高可达0.315N,是推力器模态的最佳选择。

The microwave thruster without propellant is a new concept of propulsion, which has the advantage of large thrust, simple structure and high reliability. To provide help for the design study and based on the quantum theory, this paper quantized the electromagnetic field in the conical thruster cavity, educed the formula for thrust calculation. It used the finite element analysis software ANSYS to calculate the Q value of thruster cavities with different resonant modes. Then the thrust was calculated. The calculating results show that the Q value and thrust of the TE012 mode are the maximum which illustrates that it is the best choice for microwave thruster without propellant.
