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.
Why IP turbine rolling is done but not HP rolling?
Turbine maintain very good thrust force balance in IP rolling and high pressure and temp is not required in this.
Why balancing line is providing in steam turbine?
for thrust balancing.
What is the difference between a Gas turbine engine and a piston engine?
a compressor does work on the gas , raising its pressure and temperaturea 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.
What is HP and LP turbine expansion?
HP Turbine is High Performance Turbine LP Turbine is Low Performance Turbine
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 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.
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
How does a piston work on an airplane?
One believes you are talking about piston engines- such as a V-l2 or Flat-6 as opposed to Jet or turbine engines. almost all automobiles with the exception of the Rotary-engined Mazda, use piston internal-combustion engines. With aircraft there are piston engined, Turbo-Prop, and straight turbine or turbo-jets. Rockets are a bit out of the pale for common use.
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 balance piston used for a centrifugal compressor?
Due to the pressure rise developed through the impeller, a pressure difference exists across the hubs and covers such that the impellers have a net thrust in the direction of the compressor inlet. The balance piston counteracts that by being located behind the last impeller. This is accomplished by subjecting the outboard side of the balance piston to a low pressure from the inlet side of the compressor thereby creating a pressure differential opposite to the direction of the impellers. This pressure is acheived by connecting the area behind the piston to the inlet using a line. The impeller thrust not balanced by the balace piston is absorbed by the thrust bearings. I hope this helps
What is the purpose of fixing a dummy piston and cylinder in steam turbine rotor?
Dummy piston is provided to oppose the axial thrust generated (in the direction of steam) due to incoming steam.
What is the line of best fit for the piston's data?
the best of piston's the point of graph
What was used before atf as a fuel in aeroplane?
A variation of Aviation Turbine Fuel has always been used in turbine engines. Variations of gasoline have always been used in aircraft with piston engines.
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.)
How many type of air?
Several. Oil less , Turbine, Oiled Piston , single stage, two stage,etc,
