Who invented the turbofan engine?
Gerhard Neumann
What type of engine is in the Boeing 737?
turbofan
What type of engine does the Fairchild Republic A-10 Thunderbolt II use?
2 GE TF34-GE-100A Turbofan
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.
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.
