A fan blade for a jet engine, such as a turbo fan jet engine is disclosed. The fan blade includes a root for coupling the fan blade to a rotating hub. The root is connected to a blade portion or an airfoil. The blade includes a leading edge and a trailing edge. The leading edge ...
In the rare event of a fan blade separation, the fan blade must not penetrate the case of a commercial jet engine. Due to this requirement the fan case is the heaviest single component of a jet engine. With a goal of reducing that weight, a simulation of a fan blade containment system...
blade offturbine enginevery high strain rate material behaviorWith a goal of reducing jet engine weight, simulations of a fan blade containment system with an alternate geometry were tested and analyzed. A projectile simulating a fan blade was shot at two alternate geometry containment case ...
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 ...
The wedge consists of a hollow, bellows- shaped body fitted with an axial stop member, the body being inflated after mounting so that it takes up all the space between the platforms of the blades, the blade shanks and the teeth of the disc. The invention is used for damping device of ...

Fan rotor blade of the present invention provides (1) includes a blade body (10), which is formed by a fiber reinforced resin composite material, having a side facing the direction of rotation of the pressure surface (10a) and facing the rotational direction of the other negative pressure ...
Two studies of engine blade response were recently completed in which bench modal tests were successfully performed on simplified fan models. The modal test procedures for the first study were successful in extracting the modal parameters. But the tests in the second study were more demanding. ...
