A modular device for loading cartridges on board aircraft is provided equipped with pyrotechnique cartridges with electric detonator, formed from a combination of elements of small volume and low weight comprising a case means enclosing cartridges whose bases carry firing detonators and are fixed to a support plate with interposition, between the support plate and an insulating plate, a printed circuit comprising resilient zones on which are fixed the studs for firing said detonators.

A device for rapidly positioning and removing a loader in and from a carrying device on an aircraft, comprising a lever in the form of a horse shoe or stirrup having a cross leg between two side legs which support the loader and which are pivotably mounted to the carrying device at their ends opposite the cross leg, whereas this latter carries a single screw for fixing to the carrying device, actuation of this lever being facilitated by previously automatically latching the loader to the bottom of the carrying device.

A device is provided formed by a case which contains, on each side of a ball for retaining the coupling member of the belt, two spring-loaded sliding keys cooperating alternately with the ball so that the retreat of one against the action of its spring allows the automatic advance of the other one either for locking said ball in the coupling member of said belt during penetration of this member into the case, or for releasing said coupling member and automatically ejecting same, depending on the key which is moved back against the action of its spring.

This device for absorbing the kinetic energy resulting from the relative motion between two bodies comprises a tubular test-element attached to one body and a pressure member rigid with the other body and contacting a suitable longitudinal profile of the test-tube, so that during the relative movement of the two bodies the movement of the pressure member, for example in the form of a carriage provided with pairs of rollers, is attended by a plastic deformation of the cross-sectional contour of the test-tube.
