涡轮盘是涡轮喷气发动机中连接涡轮叶片和涡轮轴,推动发动机高速旋转的一个重要部件。在发动机运转中,涡轮盘受力情况复杂,容易出现故障,严重的甚至可能造成机毁人亡。因此,有些国家把它列为航空发动机中唯一由政府控制的零件,由政府发给证明规定使用寿命。 Turbine is a turbojet engine connected to the turbine blades and turboshaft, to promote high-speed rotation of the engine is an important component. In the engine operation, the turbine disk force situation is complicated, prone to failure, serious and may cause machine crash. As a result, some countries have classified it as the only government-controlled part of an aero-engine to be issued by the government to prove its stated service life.
