Abstract

The detonating valve for releasing openings of air bag landing systems for aircraft and spacecraft has a wedge type charge and a cover closing the opening, which cover is shorn off during the ignition of the wedge type charge. The cover is a thin-walled disk or a membrane, which is integrated either within the aircraft and spacecraft or within the air bag landing system.

Claims

1. A detonating valve for releasing openings of air bag landing systems for aircraft and spacecraft, comprising:

a wedge type charge;

an igniter;

a cover closing the opening, the cover being shorn off during the ignition of the wedge type charge, said cover cover being a thin-walled disk;

another igniter associated with said wedge type charge, said the igniter and said another igniter and the wedge type charge being arranged in a mounting ring, said mounting ring being in contact with the disk to be shorn off;

a support ring, which limits a cutting point and surrounds the disk to be shorn off, provided on a side of said disk, said side of said disk facing away from said mounting ring, a side of said mounting ring facing away from the disk to be shorn off being in contact with an adapter; and

a diaphragm limiting the diameter of the opening provided on a side of the adapter facing away from the mounting ring.

2. The detonating valve in accordance with claim 1, wherein said wedge type charge is a detonating cord, which is placed partly into a groove in said mounting ring and partly into a corresponding groove in the disk.

3. The detonating valve in accordance with claim 1, wherein the diameter of said diaphragm is adjustable.

4. The detonating valve in accordance with claim 2, wherein the diameter of said diaphragm is adjustable.

5. The detonating valve in accordance with claim 1, further comprising at least one of pressure sensors and distance sensors which trigger the igniters, associated with said detonating valve.

6. The detonating valve in accordance with claim 2, further comprising at least one of pressure sensors and distance sensors which trigger the igniters, associated with said detonating valve.

7. A detonating valve for releasing openings of air bag landing systems for aircraft and spacecraft, comprising:

a wedge type charge;

an igniter;

a cover closing a valve opening, which cover is shorn off during the ignition of the wedge type charge;

another igniter associated with the wedge type charge;

a disk comprising a flexible membrane;

an edge reinforcement, said membrane being limited by said edge reinforcement surrounding said membrane said igniter and said another igniter being arranged on an outside of said edge reinforcement; and

wherein a wedge type charge is welded into said edge reinforcement at the connection point between said membrane and said edge reinforcement.

8. The detonating valve in accordance with claim 7, wherein said wedge type charge is a detonating cord.

9. The detonating valve in accordance with claim 7, further comprising at least one of pressure sensors and distance sensors, which trigger the igniters.
