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.

What are the advantages of free turbine engine over gas turbine engine?
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.
What is the difference between balancing piston and balancing drum in compressors?
They are the same thing.
What is balance piston line of Turbine?
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.
How a helicopter engine works?
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.
What are the examples of cotter joint?
*joint between the piston rod and and the crosshead of the steam engine *joint between the slide spindle and the fork of the valve mechanism *joint between the piston rod and the tail
What is the difference between a Gas turbine engine ignition system and a piston engine ignition system?
Main difference is that in a gas turbine, combustion is continuous. In a piston engine, combustion is pulsed.
What is a difference between turbojet engine and piston engine?
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.
What is a helicopter powered by?
They are either powered by a turbine engine like a jet engine or a piston engine.
What is the difference between steam turbine and water turbine?
turbine is driven, engine drives. in reality nothing, both use steam pressure to create a desired output. motion, turbine has 1 moving part that spins on it's axis. engine has many moving parts spinning an axis (crankshaft) I really feel there is a huge difference in the way the two power generating sources work. The turbine uses steam at higher pressures and in my view less efficently than a closed piston power source does. lower pressures can be used in the closed piston type engine and levels of output can be changed by simply adding more cylinders or expanding the diameter of the piston,there are more moving parts than a turbine but if you figure in the steam adjust valves probally not that many more. I have never understood why an turbine is used as opposed to closed piston type engine. Thank you. _____________________________________________________________________ A turbine opperates in a way similar to either a jet engine, or an old water-wheel. In either case, a steam turbine converst the thermal energy of the steam to rotary mechanical energy much more efficiently. An engine (either a single set like a locomotive, or a block like a gas or diesel engine) uses both the pressure and the expansive poer of the steam to move a piston. The piston is connected to a rod which connects the backand forth motion of the piston to the rotary motion of the crankshaft. A turbine is most fuel efficient in situations where full power is used most often, such as a powerplant, where the tubine spins a generator. An engine is most efficient in low-speed, high torque applications, such as a pisotn set coupled to the drive wheels of an old steam locomotive. The steam produced for a steam engine drives a piston up and down or left to right, while the steam produced for a steam turbine turns the turbine itself.
Is there any difference between piston ring of naturally aspirated engine and turbo charge engine?
yes
What is the use of a turbine in refrigeration?
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.
What is the difference between jet and airplane?
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."
Is there any difference between piston rings of naturally aspirated engine and turbo charge engine?
YES!!!!! As well as the pistons!
How do you pressurize an aircraft?
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.)
What are the advantages of free turbine engine over gas turbine engine?
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.
Is the Robinson r22 piston or turbine driven?
because they have a light weight frame they are able to get away with a piston engine witch make is that much cheaper
What is the difference between a 3.7L engine and a 3.5L engine?
The 3.7L has more cc's and slightly bigger cylinders with piston heads than the 3.5L.
