FLUID EXPERIMENT APPARATUS FOR AIRCRAFT
Document Type and Number:
Japanese Patent JP2001025669
Kind Code:
A
Abstract:

To recover liquid easily and to perform a fluid experiment in a closed system by generating a pressure difference between a cell of a closed system installed in an aircraft and a recovery container connected to the cell and discharging the liquid from the cell into the container.

After liquid was supplied from a cylinder 1 for supplying fluid into an experiment cell 2, and an agravic experiment is implemented, the liquid retained in the bottom part of the cell 2 is recovered in a recovery container 3 without being opened to outside air. In other words, the motor 26 of the cell 2 is driven to bring down a lower part disk 21, a liquid column is formed between it and an upper part disk 28, which is observed each camera 23, 24. After that, an agravic state is finished, and the liquid of the collapsed liquid column is stored in the bottom part of the cell 2. After the recovery valve 30 of the container 3 is opened, a guide member 34 is elevated, and the volume of the container 3 formed in the shape of bellows is increased.
