How much does a jet fan blade weigh?
Each fan blade weighs between 30 and 50 pounds. Every GE90-115B engine contains 22 of these fan blades, which add approximately 2,000 pounds to the engine’s thrust capability, while providing better fuel burn.
How fast do jet engine fan blades spin?
around 3,000 RPM
In flight, the fan blades spin at around 3,000 RPM. Any higher and the fan tips start to run supersonically, making a huge amount of noise in the form of a piercing drone. In contrast, the low pressure shaft spins at 12,000 RPM and the high-pressure shaft at around 20,000 RPM.
What is a jet engine fan blade?
A fan disk is the central hub of a fan in a turbofan engine. Fan blades are attached to the fan disk, which is rotated by a shaft driven by a gas turbine. In modern passenger aircraft, most of the propulsive thrust comes from fans, which are driven by gas turbines.
Why is the GE90 fan blade so important?
Plus, the aerodynamic design allows the GE90 fan blade to pull large amounts of air into the engine, making it quieter and more efficient while generating unrivaled thrust. A later variant, the GE90-115B fan blade, was introduced into New York’s Museum of Modern Art in 2007 as a perfect example of cutting-edge engineering, design and beauty.
How big is the fan blade on a GE jet engine?
This single fan blade comes from the GE90-115B, one of the largest and most powerful jet engines in the world. The engine contains twenty-two fan blades, each of which is four feet long and weighs less than fifty pounds.
What makes the GE90 engine so efficient?
The GE90 fan blade’s uniquely curved design makes it larger, lighter and more aerodynamic than traditional titanium blades for reduced engine weight and lower fuel burn. Plus, the aerodynamic design allows the GE90 fan blade to pull large amounts of air into the engine, making it quieter and more efficient while generating unrivaled thrust.
What kind of material is Ge Fan Blade made of?
Composite technology has allowed GE to design a uniquely formed curved blade that is lighter, more aerodynamic, and larger than traditional titanium blades. The GE90-115B blade is made of carbon fiber and a toughened epoxy matrix, a composite material that is extremely flexible yet highly resistant to impact.
