A recently granted patent (Publication Number: US11965462B2) discloses an innovative aircraft design featuring a wing, flight propulsion drive, and engine pylon retainer. The aircraft includes a unique cooling system for the exhaust gas of the flight propulsion drive, comprising a heat exchanger and a condenser situated in a bypass duct. The condenser is designed with one or more sections arranged concentrically to the flight propulsion drive's axis of rotation, enhancing the cooling process. Additionally, a water removal channel with a removal apparatus separates water from the exhaust gas after it passes through the heat exchanger, ensuring efficient operation.

Furthermore, the patented aircraft design incorporates a steam supply device connected to the heat exchanger, enabling the supply of steam to the flight propulsion drive's combustion space. A steam turbine positioned between the heat exchanger and the steam supply device can drive at least one compressor of the flight propulsion drive. The patent also details the inclusion of various components such as gaskets, separation plates, swirl generators, and turbine stages in the water removal channel to optimize the separation process. The aircraft's method of operation involves the cooling of exhaust gas and separation of water by the heat exchanger and removal apparatus, respectively, showcasing the innovative and efficient design of the aircraft.
