本文介绍一种设计固体火箭喷管的新方法。这种方法以拉伐尔喷管内非对称流动理论为基础,首先着眼于减少气动偏心,然后考虑效率。它与传统的方法并不矛盾,而仅是其合理的补充。采用这种设计方法将有助于减少无控火箭的散布。
This article describes a new method for designing solid rocket lances. This method is based on the Laval nozzle asymmetric flow theory, focusing first on reducing aerodynamic decentering and then on efficiency. It does not conflict with the traditional method, but only its reasonable complement. Using this design method will help to reduce the spread of uncontrolled rockets.
