Abstract

Turbo-fan gas turbine engines, or simply turbo-fan engines (STFEs), are used for powering both manned aircrafts and unmanned air vehicles (UAVs). The high pressure turbine section of such engines use Ni-base superalloy cast rotor blades because of their good mechanical properties at high operating temperatures. The present paper provides the technical/technological details of the various aspects associated with development and manufacturing of high pressure turbine blades (HPTBs) for utilization in an indigenously-developed small turbo-fan engine. Vacuum investment casting process has been adopted for realization of the above equiaxed components using a Ni-base superalloy

小型涡轮风扇发动机高压涡轮叶片熔模铸造工艺的实现

涡轮风扇燃气涡轮发动机，或简单的涡轮风扇发动机(stfe)，用于为有人驾驶飞机和无人驾驶飞行器(uav)提供动力。这种发动机的高压涡轮部分采用镍基高温合金铸造转子叶片，因为它们在高温下具有良好的机械性能。本文提供了与高压涡轮叶片(hptb)的开发和制造有关的各个方面的技术细节，用于国产小型涡轮风扇发动机。采用镍基高温合金，采用真空熔模铸造工艺实现上述等轴部件;
