What is the Difference between engine powered airplane and jet airplane?

Answer 1

A basic aircraft engine is a reciprocating engine of different shapes (radial, inline, opposing or V shaped) that operate similarly to an automotive engine. (The internal pistons push on a drive shaft) The drive shaft turns a propeller instead of wheels. These engines utilize a gasoline fuel very similar to auto fuel but at higher octane. Jet engines are utilized by jet aircraft and turboprop aircraft. Jet engines compress outside air, mix it with fuel (essentially kerosene) and ignite the fuel, whereby, the expanding gases flow out the exhaust with sufficient velocity to push the aircraft forward or to drive a propeller shaft. The jet engine air intake has one or more series of spinning compressor vanes that draw in and highly compress the outside air. This compressed air is mixed with fuel and ignited in the combustion chamber. The expanding gases flow out the exhaust with great velocity that produces sufficient thrust to move the aircraft forward. A turboprop jet engine adds 1 or more series of vanes into the path of the exhaust that absorb most of the energy from the exhaust. These spinning vanes within the exhaust or "turbine" section drive a shaft that drives a propellor. Pure jets are more efficient at higher altitudes whereas turboprops can be more efficient at lower altitudes and shorter distances.
