The turbine engine is actually a engine using air as a operating fluid to supply thrust.
To achieve this, the air passing through the engine should be accelerated; this implies that the speed or mechanical energy of the air is accumulated. to get this increase, the pressure energy is 1st of all accumulated, followed by the addition of warmth energy, before final conversion back to mechanical energy within the kind of a high rate jet outflow.

Working cycle and airflow ( Chapter 2/25) PDF.
Rolls-Royce Jet Engine
The operating cycle of the turbine engine is analogous to it of the four-stroke piston engine.
However, within the turbine engine, combustion happens at a continuing pressure, whereas within the piston engine it happens at a continuing volume. each engine cycles (fig. 2-1) show that in every instance there’s induction, compression, combustion and exhaust Aviation courses.
These processes are intermittent within the case of the piston engine while they occur endlessly in the turbine. within the piston engine just one stroke is used in the production of power, the others being concerned within the charging, compression and exhausting of the operating fluid. In distinction, the rotary engine engine eliminates the 3 ’idle’ strokes, therefore enabling additional fuel to be burnt in a very shorter time; therefore it produces a bigger power output for a given size of engine.
3. because of the continual action of the rotary engine engine and also the indisputable fact that the combustion chamber isn’t an indoor area, the pressure of the air doesn’t rise, like that of the piston engine, throughout combustion however its volume will increase. This method is thought as heating at constant pressure aviation courses.
Under these conditions there are not any peak or unsteady pressures to be withstood, as is that the case with the piston engine with its peak pressures in way over one,000 lb. per sq. in. it’s these peak pressures that build it necessary for the piston engine to use cylinders of serious construction and to use high hydrocarbon fuels, in distinction to the low hydrocarbon fuels and also the lightweight invented combustion chambers used on the rotary engine engine aviation courses.
