PURPOSE:To permit blade cooling to increase its degree by partly supplying cooling air of high temperature from a compressor to be cooled by the atmospheric air through a heat exchanger. CONSTITUTION:A heat exchanger 14, surrounded by an air-introducing cover 13, is mounted to the outside ...
A turbine engine, having a cooling passage diverting a part of the airflow from the turbine compressor for impingement upon the turbine blades, includes a concentric pair of apertured rings disposed in the passage for variably obstructing flow through the cooling passage between zero and a maximal...
including rapid heating, sustained high temperature, and cooling. Therefore, it is crucial that this cycle does not affect the structural integrity of any turbine blade, as the failure of a single

A turbine blade includes a platform having an internal cavity formed therein and an airfoil extending radially from the platform. An internal cooling circuit is formed in the airfoil for circulating a coolant therethrough, and at least one supply passage extends between the internal cooling circuit ...
A turbine blade used in the turbine of a gas turbine engine and cooled by cooling air is provided with: a cooling channel which is formed within the turbine blade and through which the cooling air flows; closed-end recesses (15) which are formed in a blade surface of the turbine blade ...
A small gas turbine engine turbine blade cooling (A1), comprising: forming the cooling fins (1) and wherein the cooling air flowing through the cooling passage (12); forming the inner wall surface (111) to penetrate the outer wall surface ( 112) to form a film cooling film cooling holes...

The origin is the shockwaves originating at the supersonic fan blade tip at takeoff thrust.[87] 【参考译文】涡轮风扇的出现取代了非常独特的喷气噪音,取而代之的是另一种被称为“蜂鸣锯”的噪音。其起源是在起飞推力下,超音速风扇叶片尖端产生的冲击波。[87] 4.8 冷却 | Cooling Adequate heat transfer ...
This example shows how to compute the thermal stress and deformation of a turbine blade in its steady-state operating condition. The blade has interior cooling ducts. The cool air flowing through the ducts maintains the temperature of the blade within the limit for its material. This feature is...
