This study explores an optimised thrust system layout for addressing sudden loads. Firstly, an adaptive mechanical model of a propulsion system under sudden external loads is established. Secondly, the relative variation coefficient (CRV), an evaluation index of thrust suitable for sudden loads, is proposed. Finally, on the basis of this adaptive mechanical model, the layout parameters of a uniform propulsion system are optimised to determine the layout parameters of a nonuniform propulsion system, and the prototypes of these two layout forms are virtually simulated. Simulation results are evaluated according to the CRV value. Results show that the optimised nonuniform propulsion system has a small CRV value and a good stratum adaptability. This work lays out a theoretical foundation and offers a solution for designing nonuniform propulsion systems.

这项研究探索了用于解决突然载荷的优化推力系统布局。首先，建立了外部突然载荷作用下的推进系统自适应力学模型。其次，提出了相对变化系数（CRV），一种适用于突然载荷的推力评估指标。最后，在此自适应机械模型的基础上，优化了均匀推进系统的布局参数，以确定非均匀推进系统的布局参数，并对这两种布局形式的原型进行了虚拟仿真。根据CRV值评估仿真结果。结果表明，优化的非均匀推进系统的CRV较小价值和良好的层适应性。这项工作奠定了理论基础，并为设计非均匀推进系统提供了解决方案。
