TESTING DEVICE FOR MICRO-GRAVITY ENVIRONMENT

PURPOSE:To enable easily obtaining a free floating state in micro-gravity envi ronment by so retaining a specimen as to be capable of being freely released in a container such as an aircraft capable of generating a gravity-free or micro- gravity condition, and connecting the specimen to the container with a rope. CONSTITUTION:A post 2 is suspended from a ceiling part in the airframe 01 of an aircraft, and a magnet (electromagnet) 1 is fitted to the lower end of the post 2, thereby adsorbing and retaining a specimen 02. Also, one end of a rope 3 is connected to the specimen 02, and the other end thereof is so hooked to a reel 4 fitted to the airframe 01 as to be capable of free winding. Further more, before and after an experiment in micro-gravity environment, the specimen 02 is fixed and retained with the magnet 1 and the rope 5. In this condition, the magnet 1 is demagnetized at the time of carrying out the experiment in the micro-gravity environment, and the rope 3 is paid out from the reel 4, there by releasing the specimen 02 and obtaining the floating state thereof.
