A 737 engine fan and low pressure turbine rotates at approx 5500 rpm. The high pressure compressor and turbine turns about 15000 rpm.
What is the rpm of a 777 jet engine?
The GE90—installed on some Boeing 777s—is typical in that the fan stage (N1) rotates at a maximum of 2,550 RPM while the compressor stage (N2) rotates at a maximum of 10,850 RPM. The blade tips, at 11,000 RPM, are well above Mach 1, which partially accounts for the high noise levels of a jet engine.
How powerful is a 747 jet engine?
The power per engine for the two aircraft is seen to be 14 984 horsepower and 1646 horsepower for the 747 and Super Constellation, respectively. The Wright 3350 turbocompound engines that powered the Lockheed aircraft are among the most powerful reciprocating engines ever developed for aircraft use.
How fast does a turboprop spin?
Turboprop propellors typically range from about 9000 RPM (give or take) to about 2500 RPM.
Why are jet engines so expensive?
Jet engines are so expensive, because they are getting more and more sophisticated and fuel efficient. After landing the A380, the controls to shutdown the engine were not working. Firefighters tried for hours to shutdown the number 1 engine without success.
What is that RPM of turbines?
Most wind turbines try to spin at about 15 RPM, and gearing is used to keep it at that speed. Gearing is also used with the crankshaft of a vehicle in order to keep the RPM reading in a range (usually 2000-3000 RPM). Some racing motorcycles will reach more than 20,000 RPM.
