摘要：

At present, the airborne thermal load of high speed vehicle is increasing exponentially. But the temperature of the fuselage increases with the flight time due to the aerodynamic heating effect. These factors severely restrict the endurance of the high-speed vehicle and the working time of the electronic equipment. Fuel oil can be the preferred airborne heat sink because it is necessary to be carried liquid with large ratio heat capacity. The working temperature of fuel heat sink will be affected aerodynamic heating effect, consumption rate, flight time, comprehensively. In this paper, a fuel heat management system for high speed vehicle will be studied to analyze the influence of parameters design on the flight time. The dynamic characteristic equations were established for the fuel thermal management system. The concept of thermal fight time was further proposed to evaluate the flight time constrained by thermal load effect. The effects of the above factors and the design parameters on the fuel thermal management system were discussed in detail. The above work can provide a reference for the design and selection of the thermal management system for high speed vehicle. © All Right Reserved.
