Experimental Study on Fire Resistance of Electric Vertical Take-Off and Landing Electrical Connector

As a core technology in the future of aviation transportation, the safety and reliability of electric vertical take-off and landing (eVTOL) aircraft are of paramount importance. Electrical connectors, being critical components of eVTOL systems, play a significant role in ensuring overall aircraft safety. This paper presents a systematic experimental investigation into the fire resistance performance of electrical connectors used in eVTOL systems. The study examines the behavior of various connector materials and designs under high-temperature and flame exposure conditions, as well as their fire endurance in practical applications. A series of standardized fire resistance tests were conducted to analyze the electrical performance, mechanical strength, and signal transmission stability of the connectors under fire scenarios. The results indicate that certain high-performance materials and optimized designs can substantially enhance the fire resistance of electrical connectors, thereby improving the overall safety of eVTOL systems. This research provides crucial experimental data and theoretical insights for the design and selection of eVTOL electrical connectors, contributing significantly to the enhancement of safety standards in eVTOL aircraft.
