a compressor does work on the gas , raising its pressure and temperature
a turbine does the reverse , it expands the gas as it passes through the turbine, extracting energy from the gas to do mechanical work.
For a typical jet engine , the flow track on a compressor is of a converging cross section while is it diverging for the turbine, which is as per gas dynamic laws.
The Turbine does two things here in the jet engine, one ,it runs the compressor and two, expands the gas to the propelling nozzle which produces thrust by accelerating the gas upto its exit.
Gas turbine is a rota dynamic IC engine while Piston engine is a reciprocating IC engine. Working fluid (air+gas mixture) flows continuously through rota dynamic engine but doesn't flow continuously through reciprocating engine. In case of piston engine a batch of working fluid enters in to the working chamber, goes under various processes & finally leaves out the working chamber. Next batch of fluid then enters into the working chamber & goes through the same procedure. But in a gas turbine working fluid enters continuously while going under various processes leaving the chamber simultaneously.
The difference is what is doing the work, in a gas turbine the turbine spinning does the work and in a piston engine the pistons going up and down moving the crank shaft does the work.
A gas turbine engine will usually yield more power by weight than a piston engine. Main downside is that it can't be throttled very well. Energy efficiency isn't all that good to start with, and will drop right down if it has to be operated outside its optimum range.
They are the same thing.
it is used balance axial thrust on turbine rotor due to admitting of high pressure steam in to turbine. it basic purpose is to save thrust bearing.

In a very similar way to ordinary aero engine. There are internal combustion engines which work on the induction, compression, power and exhaust system, linked through a gearbox to a shaft which drives the prop. Or the jet version which works by hot gases turning a turbine, which has a shaft running through the middle, again linked through a gearbox to a shaft which drives the prop. This is called a turboprop.
Main difference is that in a gas turbine, combustion is continuous. In a piston engine, combustion is pulsed.
I think your question is self explanatory. A piston engine develops thrust by using pistons. The turbojet engine develops thrust by rotating a turbine. Here both piston and turbine are means of converting thermal energy to mechanical energy. For the piston engine the thermal energy resulted from combustion at constant volume is used to push down the pistons which in turn rotate a shaft. For the turbojet engine(more precisely gas-turbine engine) the thermal energy resulted from the combustion at constant pressure is used to rotate a turbine which is connected to a shaft.
They are either powered by a turbine engine like a jet engine or a piston engine.
The difference is that geysers are way much hotter than the steam from hot springs. The geysers can give you 3rd degree burns. But so can the steam from hot springs if you're in there to long.
yes
It is used as a compressor. It has the same advantages over a piston compressor as a gas turbine engine has over a piston engine. i.e. no valves, much lower part count and much greater efficiency.
Any fixed-wing aircraft with an engine is an airplane. There are different kinds: piston-engine airplanes have piston engines driving propellers, (airplane engines are horizontally-opposed, like the engine in an old Volkswagen), turboprop airplanes have turbine engines with gearboxes that drive propellers, and jet airplanes have turbine engines that move the plane directly. So, factually, a jet is a type of engine on an airplane. However, over time, aircraft with jet engines have often been referred to as "jets."
There's an engine-driven compressor. On a turbine engine they pull bleed air off one of the turbine sections; on a piston engine plane it's an accessory to the engine. (Having said that, very few piston planes have pressurized cabins--they don't go high enough to need them.)
YES!!!!! As well as the pistons!
An aircraft gets thrust from an engine, either a piston engine driving a propeller or a jet driving a turbine.
A gas turbine engine will usually yield more power by weight than a piston engine. Main downside is that it can't be throttled very well. Energy efficiency isn't all that good to start with, and will drop right down if it has to be operated outside its optimum range.
because they have a light weight frame they are able to get away with a piston engine witch make is that much cheaper
