摘要
论述了载人航天中的微重力模拟方法，重点论及了失重飞机抛物线飞行及其应用，如航天部件试验，空间科学的某些项目的原理和操作试验，特别是航天员的选拔训练实验，并介绍了国外有关失重飞机概况。最后认为失重飞机是载人航天的必要设备之一。
Weightlessness is
one of the most important factors in spaceflight.Inorder to train astronauts and to test design
concepts and operational procedures,a micro-gravity environment is needed. Whereas by
classical simulation facilities ,simulation ofweightlessness on the earth is much more difficult.
The simple and economic method isparabolic flight , offering 15～60s microgravity depending
on the aircraft used and thequality of microgravity required. 25 to 40 parabola flights are
possible on a single flightday with a medium size aircraft , parabolic flight produces real
weightlessness in the phys-ical sense. The residual gravity is only in the range of 0.02 to
0.05G. This paper sum-marizes the simulation programme for creating a microgravity
environment , the principlesand techniques of parabolic flight , and the main requirements for
zero-G aircrafts. Casesof use of zero- G aircrafts over the world were introduced.
