The invention provides an
oil transportation heat management system design method for controlling the temperature rise of
fuel oil of a high-speed aircraft, and the method comprises the steps: building a main
oil tank heat transfer model without a built-in
oil tank based on a main
oil tank structure model; based on the fuel temperature rise curve of the main oil tank
heat transfer model without the built-in oil tank, determining the fuel consumption at the fuel target temperature; determining the initial volume of the built-in oil tank based on the fuel consumption at the target fuel temperature; based on the main oil tank structure model and the initial volume of the built-in oil tank, establishing a main oil tank
heat transfer model of the built-in oil tank; and determining the final volume of the built-in oil tank based on the highest temperature of the
fuel oil temperature rise curve of the main oil tank
heat transfer model with the built-in oil tank, the
fuel oil target temperature and the initial volume of the built-in oil tank. The method can effectively reduce the temperature of the fuel at the flight
tail section of the long-endurance high-speed aircraft, and can achieve the effects of reducing the
cavitation risk of a
fuel pump, reducing the pressurization pressure of a
fuel tank, reducing the design difficulty of fuel passing equipment, increasing the available fuelheat sink of an engine and the like.
