The More-Electric Aircraft (MEA) technology has become a leading trend for the new generation aircrafts. The electrical power sources inside the aircraft can be of many types as AC, DC or hybrid, in addition to, variable voltage and frequency mains. To maintain the aircraft system stability and availability of different sources, efficient control techniques become necessary. In this paper, a complete...
In order to establish the fault information platform that across industrial department and operation department, as well as to support improvement of civil aircraft's quality and operator's maintenance capability, based on the research of civil aircraft's fault during the operation phase, including its scope, classification and data collection mechanism, the database system and technical framework...
According to the equipment trials at base, there are many software faults such as incorrect design, inaccurate boundary, awful mistake managing, which often results in equipment faults frequently. Through the systematic analysis of software test process, this paper analyzes the disadvantages upon software process management, testers and test environment. Finally, it brings forward some improvements...
In the low-cost Unmanned Aerial Vehicle (UAV), in order to ensure the security of the system and reduce costs, degrade control system under the sensor fault state is becoming more and more highly regarded. Degrade control adopted less sensor configuration to achieve the desired control functions. In the low-cost prototype UAV research and development process, degrade control not only can reduce system...
The urgency of maintenance training is become more and more outstanding in the civil aviation industry, and the specialized training equipments are of the shortage. In view of this, the power simulation system is designed for the maintenance personnel. According to the aircraft electrical power system is multi input multi output (MIMO) and control logic is complex. Taking into account the association...
An aircraft is complex system with a great number of electronic products and mechanical equipments, and numerous faults failed to be inspected in aircraft maintenance. In most circumstance, it requires specialists to detect, diagnose and redress faults. The expert knowledge is an important aid in aircraft maintenance. This paper proposes a knowledge management method based on much maintenance experience...
CBR (Case-based Reasoning) is a strategy using to solve the current problem in terms of historical experience. Case revision is a crucial and difficult step in CBR. In this paper, the basic principle and method of CBR were discussed and case revision approach based on difference of character was presented and researched. Then the process of case revision was introduced through an example of fault...
