RECOVERABLE DATA LOGGER Russian patent published in 2012 - IPC B64D25/00 

FIELD: physics.

SUBSTANCE: logger has a housing for mounting on an article, a recoverable capsule, two belts of support-guide members and a recoverable capsule ejecting system. The ejecting system consists of a launch tube, apparatus for holding the capsule in the housing, a gas generator rigidly attached to the recoverable capsule and apparatus for actuating the gas generator. The pressure shell of the recoverable capsule is in form of a sphere. The first support-guide member is mounted on the recoverable capsule in the zone of the greatest diameter of the recoverable capsule and is configured to link the spaces inside the housing separated by the support-guide members, e.g., discretely in form of protruding elements lying on a circle. The second support-guide member is made on the housing of the gas generator with sealing on the inner surface of the launch tube. The distance along the direction of ejection of the recoverable capsule from the first support-guide member to the external outline of the article is equal to the distance from the second support-guide member to the section of the launch tube.

EFFECT: high reliability of the recoverable data logger.
