摘要:
为了对非壅塞固体冲压发动机性能进行充分优化,建立了相应的内外弹道一体化优化设计数学模型。首先构造了新的非壅塞固体冲压发动机性能预示框架。而后在此基础上,采用量子粒子群优化方法(quantum particle swarm optimization, QPSO),以巡航段和无动力下降段的总射程为优化目标,在满足推力约束的前提下,对冲压发动机的喷管喉径、进气道入口和喉部面积以及飞行攻角进行一体化优化。仿真结果表明:采用QPSO方法优化后的弹道射程较仅优化飞行攻角的方案提升18.65%,证明了一体化优化的有效性,为非壅塞固体冲压发动机的设计提供了理论基础。

Abstract:In order to fully optimize the performance of unchoked solid ramjet, the mathematical model of integrated optimization design of interior and exterior ballistics was established. Firstly, a new frame for performance prediction of unchoked solid ramjet was constructed. On this basis, quantum particle swarm optimization (QPSO) with the total range of cruise and unpowered descent stages taken as optimization targets was adopted to optimize the nozzle throat diameter, inlet area and inlet throat area, as well as the flight angle of attack of the ramjet under premise of satisfying the thrust constraint. The simulation results showed that the ballistic range optimized by QPSO method was 18.65% higher than that of the scheme merely optimizing the flight angle of attack, so the superiority of the integrated optimization was proved, providing a theoretical basis for the design of unchoked solid ramjet.
