Fault Analysis of Abnormal Opening of the Main Landing Gear Door of Civil Aircraft

Abstract

The main landing gear door is an important component of the landing gear system. The system is in a state of failure and will not play the role of extending and retracting when the door extension/retraction fault. This article analyzes the main landing gear door extension/retraction principle and fault cause of civil aircraft, deeply studies the control process and logic of the Uplock, and improves the understanding of the landing gear door extension/retraction system.
