电连接器性能退化对飞机操纵性能影响研究
Research on Impact of Electrical Connector Degradation on Aircraft Handling Qualities
摘要
Abstract
The signal transmission circuit of the flat tail servo contains multiple electrical contact components.When these components degrade due to corrosion or other factors,deviations arise between the servo's motion characteristics and the pilot's control inputs.In mild cases,this affects flight handling quality,in severe cases,it may even endanger flight safety.This study focuses on a typical electrical connector in the flat tail servo's signal transmission circuit.Accel-erated testing is conducted to analyze the connector's degradation behavior in marine environments.Results revealed patterns of appearance damage,weight changes,and electrical performance degradation.For a specific flat tail servo,de-graded connectors from accelerated testing are integrated into its signal transmission circuit.Ground tests are performed to evaluate how connector degradation impacts the servo's response characteristics and aircraft control performance.The results indicate that after the accelerated test,corrosion products appeared on the surface of the electrical connector housing,with both weight and interfacial contact resistance showing an increasing trend,while insulation resistance and dielectric withstand voltage met the criteria requirements.When the corroded electrical connectors,their tail accessories,and cables are added to the electrical signal channel of the flat tail servo test equipment,the piston movement position shifts.Compared to the uncorroded state,this deviation is consistently less than 0.5 mm.Meanwhile,such deviations re-sulted in effects on the flat tail deflection angle response characteristics and the aircraft's longitudinal static controllabil-ity.关键词
