火焰筒 burner inner liner
[动力] flame tube
- 对涡轴发动机短环直流燃烧室进行了突扩区和火焰筒头部间流场试验研究。
An experimental investigation has been carried out to study the aerodynamic characteristics of two types of annular combustor sector for the turbo shaft engine. - 结果表明:在高空条件下,火焰筒同一轴向位置的壁温随马赫数的增大而升高;
The results show that, under the conditions of high altitude, the flame tube wall temperature of the same axial position is increased with the increase of Mach number; - 燃气涡轮发动机火焰筒在非均匀温度场的作用下,材料会呈现复杂的力学行为,导致使用过程中出现裂纹而造成故障。
The combustor of gas turbine engine operates under inhomogeneous high temperature, which causes very complicated mechanical behavior of combustor's material, and makes combustor failure.
