Abstract

The application provides a cable grounding layout method for an unmanned helicopter, which belongs to the technical field of electrical interconnection system design. The method includes firstly determining the installation position of the UAV airborne equipment; secondly, setting a grounding cable in the maintenance area on the aircraft, and marking the grounding mark; finally, according to the principle of minimizing the grounding resistance, setting the grounding around the UAV airborne equipment. The grounding layout has a clear design goal, strong operability, and is easy to maintain. It greatly reduces the mutual interference between different grounding signals and improves the grounding electromagnetic compatibility of the aircraft. The grounding data has strong inheritance, which is convenient for prototype design and subsequent modification. , can facilitate the grounding maintenance and troubleshooting of the helicopter field.

Description

technical field [0001] The application belongs to the technical field of helicopter electrical interconnection system design, and in particular relates to a cable grounding layout method for unmanned helicopters. Background technique [0002] Grounding design is a very important design link in the design of the helicopter electrical interconnection system, which is divided into power supply and negative line design, lap design, and shielding design of each avionics system. With the development of helicopter avionics, the requirements for electromagnetic interference and signal interference are getting higher and higher, especially with the development of aircraft such as drones, the cable network density is extremely high, and the grounding layout is extremely important. The traditional grounding layout exists The location is not clear, the workload of statistical distribution is large, the mixed use of multiple types of grounding types, and difficult maintenance.
