Abstract

A method for producing an armored wall for an aircraft by determining an available thickness of the wall, an allowable areal mass of the wall, and an available space for a wall deformation due to ballistic impact. The method includes retrieving a parameterization of a plurality of armoring materials, which includes a parameter for each of a plurality of material characteristics for each of the plurality of armoring materials. The method also includes comparing the available wall thickness, the allowable areal mass, and the available deformation space with a corresponding parameter of the parameterization, selecting one armoring material for the wall from the plurality of armoring materials based on a result of comparing, and manufacturing a wall by supplementing the selected armoring material to a basic wall structure.

First claim

The invention claimed is:

1. A method for producing an armored wall for an aircraft, the method comprising:
determining an available thickness of the armored wall;
determining an allowable areal mass of the armored wall;
determining an available space for a wall deformation due to ballistic impact;
retrieving a parameterization of a plurality of armoring materials, wherein the parameterization comprises a parameter for each of a plurality of material characteristics for each of the plurality of armoring materials;
comparing the available wall thickness, the allowable areal mass, and the available space for a wall deformation with the parameter of the parameterization of the plurality of armoring materials;
selecting one of the armoring materials based on the comparing; and
manufacturing the armored wall by supplementing the one of the armoring materials to a basic wall structure.

2. The method of claim 1 , wherein said comparing comprises categorizing the available wall thickness, the allowable areal mass, and the available space for a wall deformation, and deducting, from a respective value of the categorizing, a value of the parameter for each armoring material, and
wherein said selecting comprises determining the armoring material having the smallest deduction result.

3. The method of claim 1 , further comprising:
determining at least one further characteristic of the armored wall to be manufactured,
wherein said comparing further comprises comparing each of the at least one further characteristic with the parameter of the parameterization.

4. The method of claim 3 , wherein the at least one further characteristic includes fire properties, environmental robustness, static capacity, manufacturing complexity, configuration possibilities, and cost.

5. The method of claim 1 , wherein said manufacturing comprises integrating the one of the armoring materials between two layers the armored wall, adding the one of the armoring materials on at least one side of a layer of the armored wall, or mounting the one of the armoring materials on the armored wall.

6. The method of claim 5 , wherein mounting includes employing at least one fastener, or an adhesive, or both.

7. The method of claim 1 , wherein the plurality of armoring materials comprises an ultra-high molecular weight polyethylene.

8. An aircraft section, comprising:
at least one armored wall manufactured according to the method of claim 1 ,
wherein the at least one armored wall separates a cockpit area from a cabin area.

9. The aircraft section of claim 8 , wherein the at least one armored wall forms at least a portion of a monument or a cockpit door.

10. The aircraft section of claim 9 , wherein the monument is a lavatory, or a galley, or a separating wall.
