Abstract

Sound insulating glazing device for aircrafts, ground or maritime transportation vehicles, buildings, or others, including glazing, a sealing joint in a shape and size corresponding to the edge of the glazing and designed for assembly on said edge, sound insulation, made of at least two materials, a first resilient material and a second material with less resilience than the first, the sound insulation being used against the field of said glazing, between the glazing and the sealing joint. The invention is also for aircrafts that are equipped with at least a glazing device and a soundproofing method for glazing.

Claims

1. Sound insulating glazing device, particularly for aircrafts, including glazing, a sealing joint in a shape and size corresponding to the edge of the glazing and planned for assembly on said edge, said glazing device being characterized by equally comprising soundproofing, made of at least two materials, a first resilient material and a second material with less resilience than that of the first, the sound insulation being used against the field of said glazing, between the glazing and the sealing joint.

2. Glazing device according to claim 1, in which the first and second materials are organized in layers used side by side, the first material being used against the edge of the glazing and the second material being used on the external side of the glazing, against the sealing joint.

3. Glazing device according to claim 1, in which the second material is metal.

4. Glazing device according to claim 1, in which said glazing is a multi-layer glazing with an external layer designed for positioning on the exterior side of the aircraft, and an internal layer, each layer being surmounted on a sound insulation of its own and of which the mechanical behavior characteristics depending on temperature are distinct, the insulation of the external layer having mechanical properties adapted to lower temperatures than the internal insulation.

5. Glazing device according to claim 1, in which at least the first material differs depending on the glazing areas.

6. Glazing device according to claim 1, in which the first material forms a matrix housing multiple inclusions of the second material, said matrix being housed in the closed envelope.

7. Glazing device according to claim 6, in which the first material is chosen in the list comprising the gels, polymers and rubber blends.

8. Glazing device according to claim 6, in which the first material is granular.

9. Glazing device according to claim 8, in which the first material is chosen from the list comprising the silicate gels and polystyrene.

10. Glazing device according to claim 1, in which the sound insulation is organized in a discontinuous way along the length of the edge of the glazing.

11. Aircraft equipped with at least a glazing device according to claim 1.

12. Aircraft according to claim 11, in which the device is used for the cockpit.

13. Soundproofing process for glazing, particularly for an aircraft, surmounted on a sealing joint, with stages consisting of:

providing a first material, resilient type;

providing a second material, less resilient than the first material;

creating with the first and secondary materials a soundproofing band;

using said band between the edge of the glazing and the sealing joint.

14. Soundproofing process for aircraft glazing according to claim 13, in which the insulating band has two distinct layers made up of first and second materials used side by side.

15. Soundproofing process for aircraft glazing according to claim 13, in which the insulating band has one layer, made of a matrix of a first material, in which inclusions of the second material are organized.
