Abstract: An aircraft having an engine, a dihydrogen tank, devices to be heated, a first air intake for taking in air at a low pressure or at an intermediate pressure, a second air intake for taking in air at a high pressure, a first heat exchanger, a first pipe which passes through the first heat exchanger and feeds the devices to be heated. Upstream of the first heat exchanger, the first pipe is divided into two sub-pipes connected respectively to the first air intake and the second air intake, and a fuel pipe that is connected between the tank and the combustion chamber and passes through the first heat exchanger. The use of heat exchangers on the dihydrogen pipe allows a regulation of the temperature of the devices to be heated and of the engine and to increase the temperature of the dihydrogen before its combustion.

Abstract: An aircraft having an engine, a tank, devices to be heated, air intakes, a heat exchanger, a pipe connecting the air intakes and the devices to be heated by passing through the heat exchanger, a fuel pipe connected between the tank and the combustion chamber of the engine, and an air pipe which feeds the heat exchanger from the fan duct. The aircraft has an additional heat exchanger installed on the pipe between the heat exchanger and the air intakes, and a diversion pipe that passes through the additional heat exchanger and is connected at each end to the fuel pipe. The use of the fuel to cool the air makes it possible to use a smaller and therefore less bulky heat exchanger.
