摘要： The installation for carrying out experiments under the condition of weightlessness or microgravity comprises a drop tube immersedin water with its end closed by a bottom. The upper end of the tube carries a service room above the surface of the water. The drop tube is connected to the floor of the water by means of an anchor chain connected to the tubes bottom and an anchor. The tube is kept in upright position by the buoyant force of the water and its tensioned anchor chain. A carriage in the service room can be positionedover the center of the orifice of the tube carrying a drop capsule with an experimental set-up. After releasing the capsule from the carriage it drops down through the tube in free fall. During the fall the experimental set-up is in the state of weightlessness the experiment being influenced accordingly. At the end of its free fall the capsule is caught by a catcing device and subsequently lifted back into the service room by means of a windlass.
