The Research of Structure Damage Assessment Method for Civil Aircraft Maintenance Program;

Airworthiness compliance is an important way to ensure the safety of civil aircraft operation.

Analyzing the importance and complexity of flight control software for civil aircraft and considering the current circumstances of onboard software,some problems are discussed in the development process of flight control software,especially the development approach to flight control software for civil aircraft with multi-channel control computers.

Through analyzing the maintenance concept development of civil airplane based on Kuhn s paradigm theory,hard-time maintenance(HTM) and reliability-centered maintenance(RCM) have been presented in the pre-science phase;the paradigm of maintenance steering group(MSG) has been demonstrated in the normal-science phase including MSG-1(HTM),MSG-2(RCM) and MSG-3.

According to the flight-test assignment assumed by Shanghai Aircraft Manufacturing Factory during manufacturing the new branch aircraft,the requirement for the measurement and control system for flight-test is brought forward.

In order to meet the requirement of the new regional aircraft electric power system(EPS) independent test,a simulator is designed to be used to simulate the relative interface function among the avionics system,engine system and the EPS.
