An aircraft fuel tank temperature rise control method comprises the following steps that a prediction result about whether the temperature rise of a target fuel tank of an aircraft in a future specific time period will meet airworthiness evidence obtaining requirements or not is obtained; and if the prediction result shows that the temperature rise of the target fuel tank cannot meet the airworthiness evidence obtaining requirement, inputting fuel oil from the outside of the target fuel tank into the target fuel tank so as to slow down the temperature rise rate of the target fuel tank. According to the control method, by pre-judging the follow-up temperature rising trend, fuel oil distribution is gradually transferred in a quantitative and graded mode, the temperature rising of the target fuel oil tank can be effectively reduced, and meanwhile the fatigue load of the outer wing structure is reduced as much as possible.

    一种飞机燃油箱温升控制方法,其中,所述方法包括以下步骤:获得对于飞机的目标燃油箱在将来的特定时间段内的温度升高是否将满足适航取证要求的预测结果;若所述预测结果表明目标燃油箱温度升高将无法满足适航取证要求,则向所述目标燃油箱内输入来自所述目标燃油箱外部的燃油,以减缓所述目标燃油箱的温度升高速率。本发明的控制方法通过预判后续的温度升高趋势,定量、分次、逐渐转移燃油分布,能够有效的降低目标燃油箱的温度升高,同时尽量降低外翼结构的疲劳载荷。
