Is gas turbine an ic engine?

Gas turbines are a type of Internal Combustion engine, however; Assuming that you want to know the difference between a recpirocating piston engine and a gas turbine engine, the simple answer is that ICE's (Internal combustion engines) create work by moving a crank that is connected to a piston. An explosion in the piston chamber pushes a piston (or series of pistons) attached to a crankshaft, which turns the shaft. The gas turbine works by turning a shaft connected to a turbine. The turbine is powered by a compressed feul-air mixture. A stream of gas is compressed with air and forced through a chamber containing the turbine. The turbine turns the shaft as a result of complex mechanics that control the movement and flow of the compressed fuel-air mixture. The basic mechanical difference: A reciprocating piston engine uses a linear "back and forth" motion to turn a shaft, and the gas turbine engines relies on a constant circular motion to turn a shaft.
