Propelling nozzle for the thrust vector control for aircraft equipped

An apparatus for cooling components of an airplane engine at least partially operated by a cryogenically stored propellant via cooling air includes an air supply line for supplying the cooling air from an outside environment. A heat exchanger exchanges the cooling air with the propellant to precool the cooling air and includes a condenser having an in-flow and an out-flow side connected to the air supply line for precooling the cooling air. A pump is coupled to a cooling air line for conveying the precooled air in a liquid or vapor state to the components to be cooled wherein the cryogenically stored propellant acts upon the condenser. A propellant tank is connected to the in-flow side of the condenser and stores the cryogenically stored propellant, wherein the out-flow side of the condenser is connected to at least one combustion system of the airplane engine.

Method and apparatus for cooling an airplane engine

A turbo engine with a gas turbine to drive propellers or propfan blades is disclosed which includes a speed reduction transmission interposed behind the gas turbine output drive shaft and the propellers or propfan blades. A cooling air impeller is provided to provide the supply of cooling air to an oil cooler for the speed reduction transmission. The impeller is arranged directly on the turbine output drive shaft.
