- Oil cooling system for a gas turbine engine A gas turbine engine fuel delivery and control system is provided with means to recirculate all fuel in excess of fuel control requirements back to aircraft fuel tank, thereby increasing the fuel pump heat sink and decreasing the pump temperature rise without the addition of valving other than that normally employed.

To ensure proper temperature, oil is routed through either air-cooled and/or fuel-cooled oil coolers. This system is used to also heat (regulate) the fuel to prevent ice in the fuel. Turbine engine’s oil systems can classify as a pressure relief and the total loss system.

Two basic types of oil coolers in general use are the air-cooled and the fuel-cooled. Air oil coolers are used in the lubricating systems of some turbine engines to reduce the temperature of the oil to a degree suitable for recirculation through the system. The air-cooled oil cooler is normally installed at the forward end of the engine.
In a turbo engine 1 a gas turbine 2 drives propellers or propfan blades 9, 10 via a reducing gear 3. An oil cooling system is provided for the reducer gear, comprising an oil cooler 7 cooled by air...
Heavy-duty direct injection diesel engines usually have an oil cooler that uses the engine coolant as cooling medium. Consequently, the engine coolant heat rejection includes the heat removed by the oil cooler. Oil cooler heat rejection consists mainly of two parts: the piston cooling and the engine rubbing friction power loss.
A gas turbine engine having a compressor and an air-cooled turbine is provided with a cooling system for decreasing the temperature of the turbine cooling air. A compact heat exchanger, rotatable with the compressor, receives a portion of the pressurized air which is bled from the compressor.
In a gas turbine engine oil temperature is measured. as it leaves the fuel cooled oil cooler (FCOC) In a gas turbine engine oil pressure is measured. after the pressure pump. The magnetic chip detectors are fitted in. return line between the engine and the scavenge pump.
What are the principal components in a turbine engine fuel system? Boost pump, fuel-cooled oil cooler/heat exchanger, ejector pump, pressure and dump valve, fuel manifold What is the danger in mixing Jet A and Jet B fuels?
Fuel Oil Coolers The fuel-cooled oil cooler acts as a fuel oil heat exchanger in that the fuel cools the hot oil and the oil heats the fuel for combustion. [Figure 6-43] Fuel flowing to the engine must pass through the heat exchanger; however, there is a thermostatic valve that controls the oil flow, and the oil may bypass the cooler if no cooling is needed.
A fuel/oil heat exchange system is proposed for an aircraft gas turbine engine for heating fuel leaving the aircraft fuel tanks before it enters the engine fuel system. The proposed system eliminates the separate fuel heater. The oil system is designed so that the fuel is not overheated at the hottest engine conditions, and the fuel/oil heat ...
