Abstract

The invention concerns a safety release device for a charge suspended from an aircraft. A so-called bus bar occupies two positions, the first called the "safety" position, in which the unlocking of any locking element connected to the charge is prevented, even if orders to this effect were given, and the second called the "cocked" position, which, in contrast, permits orders to be carried out once given. A system for suspending the charge cooperates with said bar, said system comprising a given number of means acting in such a way that, as long as the lug of the carrier vehicle is connected with the suspension system, displacement of said bar is impossible. Such a suspension system consists of a ring capable of undergoing a movement, particularly rotation, translation in a vertical plane, or rocking, only when the lug is no longer present in the opening of the ring, said movement freeing a means integral with the ring which previously impeded the movement of the bar. The invention is applied particularly to the transportation and dropping of military charges.

Dependent claims

A safety device for a munition suspended beneath an aircraft, said safety device comprising:

a sliding bar movable between a first position and a second position;
first blocking means for locking said bar in said first position;
cable release means connected between said aircraft and said first blocking means for actuating the release of said first blocking means;
at least one suspending ring engageable with a hook integral with said aircraft;
second blocking means mechanically connected to said at least one ring for locking said bar in said first position when said at least one ring is engaged with said hook;
at least two apertures in said sliding bar, each of said apertures having first and second cross sections;
a fuse lock engageable with each of said apertures, each said fuse lock including a first rectangular cross section portion engageable with said first cross section of one of said apertures when said sliding bar is in said first position for maintaining said fuse lock in a safety position and a second circular cross section engageable with said second cross section of said one of said apertures when said sliding bar is in said second position for releasing said fuse lock into an armed position,
whereby said fuse locks are released into an armed position only when said release means is actuated and said at least one ring is disengaged from said hook.
