DuPont performance resins provide wear resistance and low friction under high stress in aircraft engine fans For over 50 years, DuPont resins have helped propel aircraft fan technology. DuPont™ Vespel® is a proven performer for: • Fan blade wear strips • Abradable seals • Blade ...
The invention belongs to the field of fan blade of turbofan engine, relating to an aeroengine hollow fan blade. The blade is a combined structure composed of a blade main body and a local panel, the blade main body comprises a blade body and a complete tenon, one side of the blade ...
[30] Built around the M88's core, the fan blades are slower than the 1980s GE36 due to the reduction gear, lowering noise and the fan can be mounted at the engine front for under-wing configurations.[31] The gearbox and the blade variable-pitch technologies were validated in 100 cycles...
On the blade body has a higher rigidity than that of the blade body of the blade body so as to cover the suction direction of outside air in the vicinity of the upstream side portion of the leading edge of the blade is fixed to the sheath body (20). 护套的前端部(21b)从叶片主体的...

One avenue to improve the overall engine efficiency is to reduce aerodynamic losses by minimizing clearances between the rotating blade tips and the surrounding casing [2]. However, reduced tip clearances lead to increased risks of contact between the blades and the casing. Contact events can lead...
