| 摘 要： | 介绍了一种由活动体和固定体组成的特型燃气舵.为了解该燃气舵的相关特性及其与普通燃气舵的区别,分别对该特型燃气舵和普通燃气舵进行了数值模拟.根据数值模拟的结果,从流场、热效应、固体颗粒影响及气动性能4个方面进行了分析.与普通燃气舵相比,特型燃气舵具有抗侵蚀能力强、结构质量轻和阻力小等优点,但也有升力小的缺点.

| Abstract: | A special-type jet vane consisting of a movable body and a fixed body is pressnted.To understand its characteristics and difference from a tranditional one,numerical simulation of the special-type jet vane as well as the tranditional one was carried out.Based on the results,analyses in terms of flow field,thermal effects,solid particle effects and aerodynamics characteristics show that compared with the tranditional one,the special-type jet vane has the advantages of great erosion resistance,light structura... |
