Self-sustaining speed in a gas turbine refers to the operational condition where the turbine can generate enough thrust and power to maintain its own rotational speed without external assistance. At this point, the energy produced from the combustion process matches the energy losses due to friction and other factors, enabling the turbine to operate efficiently. Achieving self-sustaining speed is critical for the turbine to transition from startup to stable operation.

What is cranking in a gas turbine?
Cranking in a gas turbine refers to the process of initiating the engine's startup sequence by rotating the turbine's shafts using an external power source, typically an electric motor or a dedicated starting system. This action allows the gas turbine to reach the required speed for fuel ignition and combustion. Cranking is essential for overcoming inertia and ensuring smooth acceleration to operational speeds before the turbine takes over and self-sustains its operation.
Why the temperature and the pressure of gas are decreasing after flowing out from turbine?
The gas (working fluid) having flown through the turbine does some work on the turbine, converting its thermal energy into mechanical work produced by the turbine and coming out as an expanding gas with lower temperature and pressure.
Can gas turbine engine be used in trains?
Gas turbine engine deals with high temperature and pressure. So it is difficult to use it. However if certain modifications are done in it , it can probably be used in trains. And if this is done the trains would be very high speed. as it is gasturbine engines which powers aeroplanes
How do you use the word turbine in a sentence?
My dadd uses turbine to heat the gas of hiss engine after he stopped at the gas stop and didn't find any gas left. ( This may be a weird looking sentence for turbine,but at least I got an A on it. )
Where are ratchet mechanisms used?
Ratchet mechanisms used in Gas power plant for Gas Turbine. (like Barring gear in steam turbine).
What is the self-sustaining speed of gas turbine?
self sustaining speed is output of a turbine= input into compressor
What is the purpose of the gas turbine?
It sends hot gases from the combustion chamber to the 1st stage turbine blades at the correct angle and speed
Gas turbine generator?

How a gas turbine work?
Basically, a gas turbine is powered by gas under pressure, The gas is pressurized by burning some type of fuel such as kerosene, jet fuel, or propane. That heat causes air expansion, and the subsequent inflow of air makes the turbine spin. A gas turbine consists of three main parts; a combustion chamber, a turbine and a compressor. Air and fuel are mixed in the combustion chamber where it is ignited and increases in speed and power. This power is directed over the turbine blades which spin the turbine and power the compressor. It's a pretty simple process: heated fuel causes pressure and air expansion. The expanded air causes a turbine to spin. That is how gas turbines like jet engines work.
Why is the gas turbine called as the power plant?
A gas turbine is one type of power plant. It produces power by burning gas to turn the turbine.

How does EGT and gas generator speed in a free power turbine with a constant speed propeller behave when power setting is increased?
As power setting is increased in a free power turbine with a constant speed propeller, EGT (exhaust gas temperature) will rise due to increased fuel flow and combustion in the engine. Gas generator speed will also increase to maintain power output and drive the propeller at a constant speed. The engine and propeller system will work together to balance power output and propeller speed.
