前言近20年来随着宇航技术的发展,国外对失重环境进行了大量研究工作。我国也利用飞机、落塔和1-g模拟等手段开展了这方面的研究工作,对失重和低重环境下贮箱中液一气界面静平衡形状,液体重定位,出流、气蚀及晃动等问题进行了失重模拟试验和分析。本文仅就国外进行的流体静动力学,宇航工程中推进系统的液体管理及其它有关问题作综合介绍,以便有关单位参考。
Foreword In recent 20 years, with the development of aerospace technology, a great deal of research abroad has been carried out on the environment of weightlessness. China also carried out research in this area by means of aircrafts, drop towers and 1-g simulations, and studied the static equilibrium shape of liquid-air interface, liquid relocation, outflow, cavitation and shaking in the condition of weightlessness and low gravity And other issues of weightlessness simulation test and analysis. This article only on the foreign hydrostatic mechanics, aerospace engineering to promote the system of liquid management and other related issues for a comprehensive introduction to the relevant units for reference.
