I think it happens because of the altitude and the fuel burn rate get slower as they clam higher 10,000 fleet
An engine driving a propeller or a turbine causes thrust.
There is no such thing as thrust specific fuel consumption of a turboshaft engine, as a turboshaft is designed to deliver mechanical power, not thrust. This mechanical power can be converted into electric power by a generator or converted into thrust by a propeller or rotor. Basically, a turboshaft uses jet technology but is an alternative to a piston engine. While thrust specific fuel consumption doesn't exist for a turboshaft, "brake specific fuel consumption" does. It measures the rate of flow of fuel required for a certain amount of power. For example, a specific fuel consumption of 0.2 lbs/h/hp means that for every horsepower the turboshaft produces, it burns 0.2 lbs of fuel each hour.
Hi there, Gross thrust is the reaction of the momentum of the jet stream produced in a gas turbine engine.If you don't know net thrust,let me tell you.Net thrust is the resultant force acting on the aircraft.Net thrust=Gross thrust-Momentum(Intake)Drag.Don't go deep in momentum drag.When the aircraft with turbine engine,is moving...Gross Thrust is more than net thrust.and when the engine is at the rest,gross thrust=net thrust.Hope you got the answer.....Good luck in your future.

Gross thrust, means the thrust when there is not forward momentum of the jet. However, the jet has always the forward speed. When we consider this, we can calculate the net thrust as the gross thrust minus the forward momentum.
A helicopter with a jet engine. The engine is adapted to give power to a transmission, rather than thrust.
over Mach 1.4 (1400km/h) due to its jet engine and turbine.
Thrust, typically created by a propeller attached to an internal combustion or turbine engine, or by a turbofan.
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.
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.
Turbine thrust bearing active and inactive temperature is the blade in the turbine trust bearing is actual temperature change, which mitigates the active or inactive bearing.
Thrust pads are used to protect the steam turbine rotor from damage due to axial displacement due to axial thrust created by entry of steam in the turbine. generaly the pads clearence is 0.45mm for a bearing size 250mm.
An airplane gets its thrust from its engines, which intake air, compress it, mix it with fuel, ignite the mixture, and then expel the hot exhaust gases out of the back of the engine, propelling the plane forward. This thrust generated by the engines enables the airplane to overcome drag and lift off the ground.
There are a few different jet engines, but it basically needs bleed air and fuel. Air enters the engine where it is compressed and mixed with fuel. Next, the air/fuel is heated in a combustion chamber, then it is unleashed through the turbine as thrust.
