Reducing contrails by condensing exhaust gas moisture into water
A recently granted patent (Publication Number: US11904272B2) discloses a method for reducing contrails during aircraft operation by inducing condensation of moisture in the exhaust gas of the heat engine. The method involves mixing a proportion of the exhaust gas with ambient air flowing around the aircraft to create condensed-out water, separating the water on the aircraft, and injecting it into the combustion chamber of the heat engine or using it to generate steam. The separation process includes electrostatic charging of water molecules in the exhaust gas and directing charged water droplets towards a complementary pole.
Furthermore, the patent also describes an aircraft equipped with a heat engine, nozzles for conducting exhaust gas into ambient air to create a gas mixture, separators for extracting condensed-out water from the mixture, and mechanisms for collecting the separated water. The aircraft's design allows for the discharge of exhaust gas on the outer surface of the aircraft or into a mixing channel where ambient air flows during operation. The separators in the aircraft utilize electrostatic charging to separate water molecules and attract condensed-out water droplets. This innovative approach aims to reduce contrail formation during aircraft operation, potentially addressing environmental concerns associated with contrails.
