Claim 0:
1. A method for reducing contrails during operation of an aircraft having a heat engine, the method comprising:
inducing a condensation of moisture contained in the exhaust gas of the heat engine by mixing a proportion of the exhaust gas with a proportion of ambient air flowing around the aircraft during operation to create condensed-out water;
separating the condensed-out water on the aircraft; and
injecting the water resulting from the separating step into a combustion chamber of the heat engine or using the water resulting from the separating step to generate steam; wherein the separating includes electrostatic charging of water molecules in the exhaust gas and directing charged, condensed-out water droplets towards a complementary pole.
