Abstract
A heating installation for an aircraft disposed between a dihydrogen tank and an engine with a first supply line connected to the tank and a second supply line connected to the engine and comprising two branch lines connected parallel to each other between the first supply line and the second supply line. Each branch lines includes a first valve, a heating system and a second valve installed in series, upstream to downstream.

A heating installation for an aircraft having a tank configured to store dihydrogen, an engine, a control unit, a first supply line fluidly connected to an outlet of the tank, and a second supply line fluidly connected to an inlet of the engine, the heating installation comprising:
- a first branch line fluidly connected between the first supply line and the second supply line;
- and
- a second branch line fluidly connected between the first supply line and the second supply line,
- wherein a first valve, a heating system, and a second valve are installed on each branch line in series, upstream to downstream, and are configured to be controlled by the control unit,
- wherein at least one of the heating systems comprises a first heat exchanger traversed by the respective branch line, a burner comprising a first inlet, a second inlet, and an outlet, a first sub-line fluidly connected between the corresponding branch line and the first inlet of the burner, a second sub-line fluidly connected between a pressurized air source and the second inlet of the burner, an extraction line configured to be fluidly connected between the outlet of the burner and an outside environment, and,
- wherein the first heat exchanger traverses between said outlet and said outside environment.
A heating installation for an aircraft having a tank configured to store dihydrogen, an engine, a control unit, a first supply line fluidly connected to an outlet of the tank, and a second supply line fluidly connected to an inlet of the engine, the heating installation comprising:
- a first branch line fluidly connected between the first supply line and the second supply line;
- and
- a second branch line fluidly connected between the first supply line and the second supply line,
- wherein a first valve, a heating system, and a second valve are installed on each branch line in series, upstream to downstream, and are configured to be controlled by the control unit,
- wherein that at least one of the heating systems comprises a heat exchanger traversed by the respective branch line, a pre-combustion chamber installed on the respective branch line downstream of the heat exchanger, and a supply line that supplies air into the pre-combustion chamber, and
- wherein at an outlet of the pre-combustion chamber, the respective branch line traverses the heat exchanger in order to join the second valve.
A heating installation for an aircraft having a tank configured to store dihydrogen, an engine, a control unit, a first supply line fluidly connected to an outlet of the tank, and a second supply line fluidly connected to an inlet of the engine, the heating installation comprising:
- a first branch line fluidly connected between the first supply line and the second supply line;
- and
- a second branch line fluidly connected between the first supply line and the second supply line,
- wherein a first valve, a heating system and a second valve are installed on each branch line in series, upstream to downstream, and are configured to be controlled by the control unit,
- wherein at least one of the heating systems comprises a first heat exchanger traversed by the respective branch line, a second heat exchanger, a loop, in which a heat transfer fluid circulates and which successively traverses the first heat exchanger and the second heat exchanger, a burner comprising a first inlet, a second inlet, and an outlet, a first sub-line fluidly connected between the respective branch line and the first inlet of the burner, a second sub-line fluidly connected between a pressurized air source and the second inlet of the burner, an extraction line configured to be fluidly connected between the outlet of the burner and an outside environment, and
- wherein, the second heat exchanger traverses between said outlet and said outside environment.
