The invention discloses an aviation fuel fixed wing general aircraft fuel tank which comprises a first fuel tank set and a second fuel tank set, the first fuel tank set supplies fuel to an engine, the second fuel tank set is connected with the first fuel tank set, a heat exchange system is arranged in the second fuel tank set, return oil of the engine enters the heat exchange system, and the heat exchange system is connected with the first fuel tank set. Fuel oil is pumped into the engine through the first oil tank, and return oil of the engine enters the heat exchange system through an oil return pipe of the second oil tank and then enters the first oil tank through a pipeline. Through the heat exchange system, the engine return oil temperature is reduced, and the fuel oil temperature in the fuel tank is increased. Therefore, the temperature of the return oil entering the first group of oil tanks is not too high, and the temperature of the fuel oil entering the first group of oil tanks from the second group of oil tanks is not too low. Return oil of the aviation fuel engine is reused, and the temperature of fuel oil in the fuel tank is adjusted, so that an aircraft safely flies under high-temperature and low-temperature conditions.

    本发明公开了一种航煤固定翼通用飞机油箱,包括第一组油箱和第二组油箱,第一组油箱向发动机供给燃油,第二组油箱与第一组油箱连接,第二组油箱中设有热交换系统,发动机的回油进入所述热交换系统,热交换系统与第一组油箱连接。燃油经第一组油箱被泵入发动机,发动机的回油经第二组油箱回油管进入到热交换系统,再通过管路返回进入到第一组油箱。经过热交换系统,发动机回油温度降低,油箱内燃油温度升高。如此,进入第一组油箱内的回油温度不会太高,由第二组油箱进入第一组油箱的燃油温度不会太低。实现航煤发动机回油再次利用,以及油箱内燃油温度得到调节,使飞机在高温和低温条件下安全飞行。
