The propeller on a turboprop airplane engine spins to move the aircraft through the air. It acts in a way similar to that of the blade in a fan.
A ship is propelled by wind or a propeller, and an airplane is propelled by a jet engine, propeller or turboprop.
turboprop
Piston, turbojet, turbofan, turboprop to name a few.
A turboprop engine is basically a turbojet, but with a propeller connected to the shaft. Air flows in the engine, is compressed by the compressor blades, and is ignited in the combustion chamber. the resulting jet of hot gas turns the turbine blades and shoots out the exhausts. A gearbox and propeller is connected to the central shaft. The turbine and compressor blades are connected to the central shaft. When the turbine blades turn, they turn the shaft, turning the compressor and the propeller. Most of a turboprop's power comes from the propeller.
Because the propeller would turn at excessive RPMS if it were coupled directly. If a propeller reaches supersonic speeds, it actually impedes the aircraft.

A propeller airplane is, simply put, any airplane which uses a propeller for propulsion.
A turboprop engine is similar to a jet engine in that both use post-combustion gasses to drive a turbine that operates the compressor used to compress the intake (pre-combustion) gas (air) before it reaches the combustion chamber where it is mixed with fuel and is then burned. The difference is that a jet engine uses a very small turbine device sufficient to run only the compressor. The remainder of the greatly expanded gasses eject as a high thrust exhaust that forces the airplane forward. The turboprop engine, on the other hand, uses a much larger turbine that not only runs the compressor, but also turns a propeller which pulls the airplane forward.
Feathering a propeller means rotating the blades so that the leading and trailing edges are nearly parallel with the aircraft flight path to stop or minimize drag and engine rotation. Normally used to indicate the shutdown of a reciprocating or turboprop engine because of a malfunction.
An aircraft gets thrust from an engine, either a piston engine driving a propeller or a jet driving a turbine.
A propeller is like a spinning wing. The airfoil shaped blades pull an airplane forward just as an airplane's wings lift it upward. The amount of thrust created by a propeller depends on how fast and at what angle its blades cut through the air. The propeller is generally powered by a combustion engine which fires pistons and turns the propeller.
A boomerang is a angled or bent stick that when thrown in the air comes back to the thrower when it does not hit an object. A propeller is a straight crafted out stick that when attached to the engine makes the airplane move forward.
