AIRSHIP DESCENDING METHOD AND ITS DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an airship descending method and its device capable of safely and quickly recovering various types of mounted equipment and record data of observations and researches. SOLUTION: When receiving a recovery signal, an outer film of the airship A is burnt out (S1) and the fractured airship A descends. When the descent reaches a first altitude, a pilot chute 18 is flared (S2) so that a drag chute 17 is drawn out and flared by air resistance acting on the flared pilot chute 18 and the pilot chute 18 is separated therefrom (S3). When descending to a second altitude, a main parachute 16 is drawn out and flared and the drag chute 17 is separated therefrom (S4). After landing or landing on the water, the main parachute 16 is separated from the airship A and various types of the equipment and record data of the observations and researches mounted on the airship A are recovered.
