Analysis of the Current Situation and Reform of Aviation Fuel Supply System

Abstract

Airplanes are high-security modes of transportation with low failure rates. Recent airplane accidents have drawn global attention because even minor component failures can lead to serious disasters. This is primarily due to the extremely complex internal structure of airplanes, where every system and even the smallest component is equally vital. It is challenging to ensure thorough safety for every tiny component of an airplane. Consequently, various aviation accidents have occurred since the inception of airplanes. This article firstly introduces the fuel system of airplanes, then analyzes the classification and manifestations of fuel system failures, and finally selects three relatively typical fuel system failure cases for targeted analysis.

In the first part, the basic overview of airplane fuel provides a brief summary of the purpose of establishing the fuel system by introducing its functions and characteristics.

The second part introduces the fuel system and its subsystems of the ARJ21 aircraft. It also discusses the sources and hazards of airplane failures by combining the classification and characteristics of aircraft faults.

The third part is the analysis section, which analyzes two maintenance cases of airplane fuel system failures through systematic working principle analysis. It employs fault tree analysis to identify the causes of failures in maintenance cases.

The fourth part is a systematic analysis of the civil aviation electrical system based on knowledge method, including two aspects: the construction of the systematic model based on civil aviation aircraft experts and the expression and organization based on knowledge. The research is mainly carried out from three aspects: data dictionary table, rule base and case base.

The fifth part is based on fault tree method to carry out systematic analysis of civil aviation electrical system, firstly analyzes the fault tree research method, and then analyzes the system fault tree and its reliability case study.
