摘要:
The present invention relates to the field of devices for airdropping a load from a flying vehicle, wherein specifically the aim of the invention is to provide a device for securing/releasing a first element (65) capable of supporting a load of more than 20 kg, as well as a second element capable of supporting said first element and said load, said second element comprising a carrier (1) on which a first means comprising a sensor (26), for example an altimeter or chronobarometric sensor, is attached, said sensor being capable of triggering the release of said first and second elements upon exceeding a threshold or receiving an external signal, in which the second element includes a hook (3) consisting of two portions, one (14) of which is movable between an operative position and a inoperative position, and means (7, 8, 25, 71, 76) for locking and unlocking the movable portion of the hook in the operative position thereof.
