Abstract

According to an embodiment, a method is provided for preparing a reconditioning of a damaged portion of a component, particularly of an aircraft, by adding an insert, which fills and/or bridges the damaged portion. The method involves: producing a 3D CAD repair model of the damaged portion by scanning; analyzing the repair model and thus evaluating complexity of the damage and/or its reconditioning; as a function of the complexity, deciding between at least two alternative means to perform at least a following step, which is analyzing the repair model and thus dimensioning the reconditioning including the insert. Further, an insert is provided for filling and/or bridging a damaged portion for reconditioning of the damaged portion of a component, particularly of an aircraft, produced according to the method.

First claim

What is claimed is:

1. A method of reconditioning a damaged portion of an aircraft component, the method comprising the steps of:
scanning the damaged portion to produce a 3D CAD repair model of the damaged portion;
analyzing the repair model to evaluate complexity of the damaged portion and/or complexity of reconditioning of the damaged portion;
selecting, as a function of the evaluated complexity, between a plurality of different computer programs of a plurality of different computers, wherein the selecting results in a selected computer program of a selected computer having available calculation power for the evaluated complexity;
analyzing the repair model with the selected computer program of the selected computer to calculate dimensional and/or mechanical parameters for reconditioning of the damaged portion, including information required to produce an insert to be used to repair the damaged portion.

2. The method according to claim 1 , further comprising the step of removing material from the damaged portion to simplify shape of the damaged portion.

3. The method according to claim 2 , further comprising the step of simplifying the CAD repair model.

4. The method according to claim 1 , wherein the step of analyzing the repair model to evaluate complexity is performed by comparing the repair model with a 3D CAD original model of the damaged portion in an original and undamaged status.

5. The method according to claim 1 , wherein the step of analyzing the repair model to evaluate complexity is performed using dimensional and/or mechanical parameters of the repair model.

6. The method according to claim 1 , wherein the step of analyzing the repair model with the selected computer program is performed by comparing the repair model with a 3D CAD original model of the damaged portion in an original and undamaged status.

7. The method according to claim 1 , further comprising the step of:
producing the insert.

8. The method according to claim 7 , wherein the insert is produced having at least one surface complementary to the CAD repair model.

9. The method according to claim 7 , wherein the insert is produced having at least one fastening structure integrated and wherein the method comprises the step of working the damaged portion and thus creating a complementary structure adopted to cooperate with the fastening structure creating a complementary structure adopted to cooperate with the fastening structure.

10. The method according to claim 7 , further comprising the step of:
inserting the insert into the damaged portion and fastening the insert to the component.
