How thrust is produced in Boeing 747?
Four GE turbofan engines generate 56,000 pounds of thrust each. This adds to 224,000 pounds of thrust altogether.
What helps an airplane to move?
Thrust, typically created by a propeller attached to an internal combustion or turbine engine, or by a turbofan.
Is the aircraft b-2 a jet?
Yes it is. It has four General Electric turbofan jet engines each generating 17,000+ lbf of thrust :)
What type of engine does a B52 have?
The B-52H has eight Pratt & Whitney TF33-P-3 turbofan engines, each providing more than 17,000lb of thrust.
Which piece of of the jet engine creates the thrust?
There are three types of jet engines that are used on aircraft, the turbojet- the turbofan and the pulsejet which is rarely used the turbofan is usually used on most common airliners and uses a combination of compressing fans in the mouth of the duct and then sends the compressed air to the COMBUSTION CHAMBER where its ignited and then it rushes out the back of the engine!
What kind of jet engine does an F-22 Raptor use?
The Lockheed Martin/Boeing F-22 Raptor uses 2 Pratt & Whitney F119 turbofan engines, with thrust-vectoring capability.
Which engine is more efficient in jet engines. Turbo jet or the Turbo fan?
The term "Turbofan" is actually quite broad, but can be broken down into two categories…high and low bypass. The question you are really trying to ask is which engine type (high bypass or low bypass) turbofan engine is more efficient? High bypass engines are used on most commercial airplanes (except the Concord) and these engines are favorable because they have a balance of high thrust, and efficiency. Aircraft that need supersonic capabilities (like the Concord) use a low bypass turbofan engine. These engines produce the thrust required to propel a plane beyond the speed of sound, but at the cost of efficiency. They burn a lot of fuel in doing so. So one could draw the conclusion that high bypass turbofan engines are more efficient, but this would not be true. In order to propel a plane beyond the speed of sound the low bypass turbofan engine is the most efficient way of doing so. On the flipside, the high bypass turbofan engine is most efficient for practical air travel. Both engine types are very different, but each are specialized to achieve different goals.
When was the turbofan invented?
1929
How does bypass produce thrust in turbofan engine?
There are two types of turbofan engines- high bypass and low bypass engines. About 80 percent of the total engine thrust from a high bypass turbofan engine is produced by the bypass of air around the core. These types of engines generally have a large fan in the front to pull in large volumes of air to produce such a powerful jet stream out the back. The front fan is driven by the compression, combustion, and expulsion of the hot gases out the back of the core. About 20 percent of the air pulled in from the front fan is used to drive the core. High bypass turbofan engines are used on almost all commercial jet aircraft because they burn less fuel. A low bypass engine is exactly the opposite. The core is used to drive a smaller fan in the front which only about 20 percent of the total volume of air pulled in is bypassed. The remaining 80 percent of the air being drawn into the engines core is compressed, combusted, and the hot gasses expelled out the back to produce the necessary thrust to propel a jet forward. Low bypass turbofan engines are found on jets that require supersonic speeds. These engines are incredibly powerful but at the cost of a high fuel burn rate.
How does an airplane accelerate?
An aircraft uses a turbofan engine to reach takeoff and cruising speed. Look up TURBOFAN on Google for more info!
What type of starting system in high bypass turbofan engine?
High Bypass turbofan engines use pneumatics (air) for starting the engines.
Who invented the turbofan engine?
Gerhard Neumann
