Abstract: An ejector seat device for aircraft includes a support structure which is adapted to be mounted in an aircraft and which can be ejected in an emergency, a seat connected to the support structure, a harness system which is capable of keeping a person in the seat and which comprises a recall device to immobilize the person in a suitable position at the moment of ejection, at least one pyrotechnical catapult capable of ejecting the support structure and the seat, together with a person sitting on the seat, out of the aircraft, a device for at least weakening the aircraft canopy by shock wave, a control handle, and an initiator connector to the handle for transforming a pull on the handle into a pyrotechnical signal. The pyrotechnical signal from the handle is transmitted in the form of a shock wave to the harness recall device and to the catapult.

Abstract: Device for ejecting a load slung under an aircraft, designed to impart to this load, at the moment of its release, kinematic values controlled as a function of the instantaneous flight parameters of the aircraft at this moment.A plurality of separate modules (1, 2A, 2B, 4, 10) makes it possible, on the one hand, to execute a longitudinal translational movement (d) of the load (3) to detach it from the members (5) attaching it to the aircraft and, on the other hand, to carry out an accurate adjustment of the angular ejection speed. One of the modules is an energy source (1), such as a bottle of compressed nitrogen. Two other modules are respectively a front fluid jack (2A) and a rear fluid jack (2B), both with a retractable telescopic piston which, when the pressurized gas is supplied to it by the source (1), exerts an ejection force on the load (3).The invention is used for the release of loads carried by aircraft.

Abstract: When the pilot seated at the front of a high-performance two-seater aircraft equipped with a forwardly-plunging transparent canopy transparency, wants to bail out on his ejection seat, he triggers a two-period pyrotechnical sequence; first, he cuts out a well-bounded fragment or dome located towards the rear of the canopy and right above his head on the seat ejection axis; and only then, upon a second period, he renders frangible the forwardly-plunging front portion of the canopy located above his knees which, at this instant, reach its level and smash it to pieces.
