The Research on Hidden Failures of Civil Aircraft

Abstract

The hidden failure is often appear on civil aircraft, and it is a big risk for normal safe operation. The reason for this failure is the instability of the resistance of the electrical contact. The study on electrical contact is applied science of the reliability, the contact resistance is an important parameter of the reliability of the electrical contact system. In this paper, It also Produces the latest research results from factors that affect contact resistance and contact resistance microscopic model, and then it produces the method of the calculating and measuring engineering about the contact resistance. Lastly, it is point out the future direction of the electrical contacts.
