Estimating the term…
A device and a method of temporarily increasing power of at least a first turbine engine is disclosed. The device includes a coolant liquid tank and a first injection circuit connected to the tank and leading to at least one injection nozzle suitable for being installed upstream from at least one compressor stage of the first turbine engine. This first injection circuit includes at least a first flow valve configured to open when a pressure exceeds a predetermined threshold compared with a downstream pressure from at least one compressor stage of a second turbine engine so as to enable the coolant liquid to flow towards the injection nozzle of the first injection circuit.
A device for temporarily increasing the power of at least a first turbine engine, the device comprising:
A method of temporarily increasing power of a first turbine engine, wherein a first flow valve of a first injection circuit connected to a tank of coolant liquid and leading to at least one injection nozzle upstream from at least one compressor stage of the first turbine engine opens when pressure upstream from said first flow valve is greater than downstream pressure from at least one compressor stage of a second turbine engine by an amount that exceeds a predetermined threshold so as to enable coolant liquid to flow through the first injection circuit and be injected by said injection nozzle upstream from at least one compressor stage of the first turbine engine, said tank being pressurized by at least one pressurization circuit connected to at least one compressor stage of the first turbine engine and including a check valve in order to avoid depressurizing the tank.
