减压阀在机载雷达中的应用

The Application of Reducing Valve to Airborne Radar

本文就飞机机动飞行时因其液压系统油源压力有时突然下降而使雷达瞬时丢失目标这一问题,比较了国内外同类产品的各种方案,介绍了在雷达液压伺服系统中串接一减压阀来“隔离”飞机油压系统干扰的方案,并从理论和实验上证明此方案是可行的。这给飞机在重量、性能及空间安排上带来了好处。

When the carrier is manoeuvring,the airborne radar may lose its targets due to a sudden drop of the oil pressure in hydraulic system of the carrier.By comparing various Schemes of similar types of radar at home and abroad,a technique using a reducing valve in radar hydraulic servo-system to isolate the disturbance of oil pressufe system of the carrier is presented in this paper.This technique is proved to be practicable both in theory and in experiment,and benefits the carrier in its weight,performance and structure.
