Question

: Differentiate between the Ground Power Engine and Jet Engine of an Airplane.​

Answer 1

Answer:

Modern jet engines in aircraft are turbofans, which have a large fan at the front which provides most of the thrust. Some of the air near the hub of the fan goes through the core to generate the power to drive the fan, but most of the air bypasses the core. Early turbines were turbojets, in which all of the air goes through the engine, just like a power plant turbine. Turbojets are not as efficient as turbofans, and are very noisy also. The power generation turbines are usually single spool, particularly the very large ones (H-class). Some power generation turbines are aeroderivative, which use a modified aircraft core to provide hot gas that drives a power turbine, sort of the reverse of a fan. Aircraft gas turbines have very thin, lightweight structures, whereas land based power generation turbines use thick, heavy designs, with the emphasis on long life. This is difference of the Ground Power Engine and Jet Engine of an Airplane.​
