Solid-State Power Controller (SSPC) is a key device in the advanced aircraft power distribution system. It replaces the traditional electromechanical circuit breakers, contactors and relays to switch loads on/off and provides comprehensive protection functions. The large surge current, which results from the starting of large capacitive loads, is similar to the short-circuit fault, so it may mislead...
In order to alleviate the increasingly serious air traffic congestion problem, a new airspace structure named air highway was proposed by researchers, who have been designing and improving the operation methods and rules for air highway ever since. According to the operation characteristics of air highway, this paper proposes a slot allocation method for aircraft to enter an air highway. Taking into...
Wire on-line detection technology is significant to aircraft wire fault diagnosis. Spread Spectral Time Domain Reflectometry (SSTDR), which is an effective method for wire fault detection on-line, is studied and analyzed in this paper for aviation field. Simulation platform and experimental system with FPGA as the core are established. Based on test results, this method is verified to be effective...
Arc faults generally cause a significant amount of heat and high temperature, thus leading to a potential fire. In order to ensure the security of wiring system, it is needed to be detected. A method to detect AC arc fault based on Mahalanobis distance is proposed in this paper. The characteristics of both normal current and arc current are analyzed, and then Mahalanobis distance is obtained through...
This paper introduces a reliability assessment algorithm based on minimal cut sets which is suited to evaluate the reliability of the aircraft and spacecraft power distribution network. According to the raw reliability data of the components of two different DC power distribution networks, the reliability of two distribution networks can be evaluated.
Purpose: In this paper, the planes were taken as reference, simulating series of flexible instruments, including artificial horizon, altimeter, steering meter, air speed indicator and so on. After connecting with flight emluator, simulation flight can be processed with keyboard and mouse. Emulational instruments will display real-time data of flight state. Methods: Firstly, Photoshop was used to deal...
The sector partition is an important part of airspace planning. The research on the sector division methods is of great significance in controlling to clear the air traffic flow in the region, relaxing the pressure of air traffic controlling effectively, and increasing air traffic flow to ensure flight safety. This paper provides the new method of sector division based on the Power diagram. With Power...
