本文根据通用型地空导弹的飞行特性提出了一种与通常定压力体制不同的变压力(或分级压力)体制液压系统。这种系统方案的设想:“力图使功率利用与工况变动相匹配,充分挖掘设计潜力,在保证基本使用性能的前提下,着重于设计方案的合理性与经济性,尽量提高系统效率,减轻结构重量,获取最优的综合战术技术性能”。文内还对这种新设想方案在工程应用方面的可能性和技术途径作了一定的探讨,并介绍了压力分级,转换速压选择和功率得益确定的考虑方法.
In this paper, based on the flight characteristics of the general SAM, a hydraulic system with variable pressure (or staged pressure) system is proposed, which is different from the usual constant pressure system. The idea of such a system solution: “Trying to match the power utilization with the change of working conditions and fully tap the potential of the design. With the premise of guaranteeing the basic performance, the rationality and economy of the design scheme are emphasized, the system efficiency is maximized, Structure weight, access to the best comprehensive tactical and technical performance. ” The paper also discusses the possibility and technical approach of this new concept in engineering application and introduces the methods of pressure grading, selection of speed-switching pressure and determination of power gain.
