Outline and Notes about Reduced-gravity Experiment by Airplane

Abstract

Since 1990, Reduced-gravity experiment flight has been carried out about 8000 parabolic flights by Mitsubishi MU- 300 and Gulfstream-II airplane in Japan. Reduced-gravity experiment flight by airplane has various features in comparison with in space experiment, besides the easy operation way further more in following point. 1. It can perform many experiment times. 2. Scientist can go through the reduced-gravity conditions. 3. Scientist can watch the actual indications in hand and can change the condition settings and controlling timing, etc. 4. Airplane can set various gravity level ( +0.03-2.5 G) with scientist needs. And this paper introduces the outline of airplane experiment, design and fabrication of experiment system, notes for good result, safety and mentioning experienced accident too.
