Abstract

The invention relates to the technical field of aircraft fuel thermal management, in particular to an aircraft fuel tank thermal calculation modeling method and a calculation model thereof. A method for modeling the thermal calculation of an aircraft fuel tank comprises the follow steps: 1, abstracting the structure of the aircraft fuel tank as the recapitulative heat transfer boundary 2, making reasonable assumptions about the internal and external heat transfer conditions of the heat exchange boundary; 3, establishing a heat exchange model of that heat exchange boundary according to a reasonable assumption. The heat transfer models of the upper panel, the lower panel and the side panels of the aircraft fuel tank established by this method can be conveniently used for the heat calculationof the aircraft fuel tank, so that they can be incorporated into the heat calculation process of the fuel oil.

Description

technical field [0001] The invention relates to the technical field of aircraft fuel thermal management, in particular to an aircraft fuel tank thermal calculation modeling method and a calculation model thereof. Background technique [0002] The establishment of aircraft fuel thermal management requires an accurate solution to the temperature change of the fuel in the aircraft fuel tank. The fuel in the aircraft fuel tank exchanges heat with the outside through the fuel tank structure. The heat exchange process includes the heat input from the outside to the fuel through the fuel tank structure and the fuel passing through the fuel tank structure. Heat output to the outside world. [0003] Due to the wide distribution of aircraft fuel tanks on the aircraft, they are installed in the wings, fuselage and engine compartment. The shapes of different parts are very different, and the contact conditions with the internal fuel and the external environment are also different, compl...
