Summary: | According to the airborne fuel tank inerting method based on fuel comprehensive heat management, fuel serves as a heat sink, heat from all systems is collected, the fuel temperature is increased, the mass transfer rate of the fuel in the fuel tank and a gas phase space is increased accordingly, the fuel steam concentration of the upper gas phase space in the fuel tank is controlled to be higher than the combustible limit concentration of fuel steam, and the fuel gas is heated to be cooled. And the oil tank inerting effect is achieved. Multiple systems and an inerting system are organically combined through the electronic equipment cooling heat exchanger, the air evaporation circulation subsystem heat exchanger, the lubricating oil system heat exchanger, the hydraulic system heat exchanger and the ram air heat exchanger, and heat on an airplane is absorbed and integrated through fuel oil; the temperature of fuel oil is increased, meanwhile, the fuel oil steam concentration in the oil tank is increased, and the |
