The turbine inlet blades of the first stage are the most likely to determine the life of the engine since they are exerted to the highest fluid temperatures, highest rotational speeds and highest aerodynamic loads. Stresses in the rotor blades also place restrictions on the allowable blade heights...

The legacy of the axial-flow engine is seen in the fact that practically all jet engines on fixed-wing aircraft have had some inspiration from this design. 【参考译文】战后,德国喷气式飞机和喷气发动机被战胜的盟军广泛研究,并为苏联和美国早期喷气式战斗机的研制工作做出了贡献。轴流式发动机的遗产在于...
is the density of the blade, and the ratio rr/rtis called the root-to-tip ratio of the blade. To prevent the blades from detaching from the hub and destroying the engine this root stress is not allowed to exceed a certain proof stress. It can be seen that the root stress is proporti...
