A blade (20) for a turbine engine includes an exterior surface. The exterior surface includes a portion having a thermal barrier coating (52) and an uncoated shelf (56) adjacent to the thermal barrier coating (52) without the thermal barrier coating (52). A cooling hole (48) extends from...
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
The turbine blades are often the limiting component of gas turbine. To survive in this difficult environment, turbine blades often use exotic materials like superalloy and many different methods of cooling that can be categorized as internal and external cooling, and the...
A turbine blade includes a platform and an airfoil extending radially from the platform. An internal cooling circuit is formed in the airfoil for circulating a coolant therethrough to cool the airfoil. At least one supply passage is provided to direct some of the coolant that has passed at lea...
turbine blades often use exotic materials like superalloy and many different methods of cooling that can be categorized as internal and external cooling, and thermal barrier coatings. Blade fatigue is a major source of failure in steam turbines and gas turbines. Fatigue is...
Turbine blade, and turbine and gas turbine including the same A turbine blade, a turbine, and a gas turbine which have enhanced cooling performance are provided. The turbine blade may include: an airfoil having a blad... HH Lee 被引量: 0发表: 2021年 Bearing support structure and a gas ...
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 ...
In a turbine blade for a gas-turbine engine impeller, which is rotationally mounted in a housing, the turbine blade has a blade tip, a leading-edge positioned upstream in the direct
The nitrogen generator separates nitrogen from air, then 78% of gaseous nitrogen is used to drive the turbine and the injection steam turbine instead of using steam. This applied technology is based on the original technology, but it is advanced by using the cooling power of gaseous nitrogen ...
