Abstract

The invention relates to a detection method for fuel oil leakage in an airplane fuel oil link. The method comprises an upstream fuel oil link detection step and a downstream fuel oil link detection step which are executed by a flight managing system or an equivalence calculation system. The upstream fuel oil link detection step comprises the sub-step of predicating an fuel oil amount, and measuring an oil tank fuel oil amount and an upstream threshold value to provide alarming information of an upstream fuel oil link; the downstream fuel oil link detection step comprises the sub-step of forecasting a fuel oil consumption amount and measuring a fuel oil consumption amount in a fuel oil box and a downstream threshold value predicating an fuel oil amount, and measuring an oil tank fuel oil amount and an upstream threshold value to provide alarming information of a downstream fuel oil link; the airplane fuel oil link comprises an upstream fuel oil link and a downstream fuel oil link. The method has the advantages that the fuel oil linkage condition of the whole airplane fuel oil link can be completely detected; the upstream fuel oil link and the downstream fuel oil link have independent alarming capabilities respectively so that the false alarm rate of fuel oil leakage detection is reduced and the judgment result of fuel oil leakage is reliable.

Description

technical field [0001] The invention belongs to the field of fuel leakage detection, in particular to a method for detecting fuel leakage in aircraft fuel links. Background technique [0002] There are usually several ways to detect aircraft fuel leakage: one way is to manually calculate the possibility of fuel leakage by the pilot, but human factors and experience often restrict the accuracy of judgment. Another way is to detect fuel leakage through sensors or other physical media. When it is found that the amount of fuel in the fuel tank has changed greatly, it indicates the possibility of fuel leakage. This method can detect the fuel leakage of the fuel tank, but it is difficult to detect the fuel leakage of the fuel pipeline. Another way is to detect the amount of fuel oil through an algorithm, such as applying the Kalman filter method to obtain a fuel consumption factor through the current fuel amount of the fuel tank and the fuel consumption of the aircraft, and provi...
