The invention relates to an oil tank, an aircraft and an oil mass measuring method.The oil tank comprises a containing cavity and an elastic film, the elastic film is located in the containing cavity and divides the containing cavity into a first containing cavity and a second containing cavity, the first containing cavity is filled with fuel oil, and the second containing cavity is filled with preset gas; the fuel pressure in the first containing cavity and the gas pressure in the second containing cavity are in a balanced state through the elastic film, and the first containing cavity is not communicated with the second containing cavity. According to the oil tank, when the remaining oil amount is calculated, the fuel oil change amount of the first containing cavity is reflected through the preset gas change amount of the second containing cavity, the preset gas change amount of the second containing cavity can be directly calculated through a formula, and the calculation precision of the volume change amount of the preset gas is high; and the calculation accuracy of the residual fuel quantity is effectively improved.

    本申请涉及一种油箱、飞行器和油量测量方法,其中,油箱包括容纳腔和弹性膜,所述弹性膜位于所述容纳腔内,且所述弹性膜将所述容纳腔划分为第一容纳腔和第二容纳腔,所述第一容纳腔内填充有燃油,所述第二容纳腔内填充有预设气体,所述第一容纳腔内的燃油压强与所述第二容纳腔内的气体压强通过所述弹性膜处于平衡状态,所述第一容纳腔与所述第二容纳腔不连通。本申请的油箱在计算剩余油量时,通过第二容纳腔的预设气体变化量反映第一容纳腔的燃油变化量,第二容纳腔的预设气体变化量可以直接通过公式计算得到,预设气体的体积变化量计算精度较高,有效地提高了剩余燃油量的计算准确度。
