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 ...
A damping device for the turbojet engine fan blades which includes a wedge placed between the platforms of the blades, the shanks of the blades, and the disc. The wedge consists of a hollow, bellows- shaped body fitted with an axial stop member, the body being inflated after mounting so ...

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...

Figure 1. Diagram of a typical gas turbine jet engine. Air is compressed by the fan blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which drive the compressor fan blades. (...
Jet engine, has low pressure compressor that is disposed axially between blades of front fan and that of aft fan, and stator with variable setting that is ... The turbofan has a low pressure compressor (7) disposed axially between blades (10) of a front fan (3) and blades (14) of ...
High-Speed Bearings & 13 CNC-machined Blades:Equipped with high-speed bearings and 13 CNC-machined stainless steel blades, this turbo violent fan generates a powerful airflow exceeding 52 meters per second. Brushless Motor & Infinite Speed Adjustment:A robust brushless motor reaches speeds up to ...
High cycle fatigue in jet engine blades is caused by excessive vibration. Understanding the dynamic response of the bladed disk system is important in determining vibration levels. Modal testing is a useful tool in understanding the dynamic behavior of structures. However, modal tests are not conduct...
