塞式喷管性能的数值模拟与实验验证

摘要

通过特征线法在塞式喷管中的应用，研究了塞式喷管主要结构参数对其性能的影响，同时，研究了塞式喷管的高度特性，最后还对塞式喷管合推力与发动机轴向夹角的高度特性进行了研究和分析。理论研究结果得到了实验的验证，其结果可用于塞式喷管的设计。%By applying the Method of Characteristics (MOC) on Aerospike nozzle,the effects on aerospike nozzle performance of the aerospike nozzle's main structural parameters are studied.And the altitude characteristics of the aerospike nozzle are studied too.At last,the altitude characteristics of the resultant force direction are given and analyzed.The results are verified by experiments and can be used for the design of aerospike nozzle.
