Abstract

A method for building an aerodynamic structure, an aerodynamic structure, and a vehicle that includes the aerodynamic structure are provided. The method includes providing a structure with at least one substantially-flat exterior surface. The method also includes attaching blocks of rigid fibrous insulation to the at least one substantially-flat outer surface of the structure. Outward-facing surfaces of the blocks of rigid fibrous insulation extend past a target outer mold line of a final aerodynamic shape. The method also includes machining the outward-facing surfaces of the attached blocks to the outer mold line.

First claim

What is claimed is:

1. An aerodynamic surface, comprising:
a structure that comprises a first substantially-flat exterior surface and a second substantially-flat exterior surface, wherein the first and second substantially-flat exterior surfaces intersect at an angle; and
a first plurality of blocks of rigid fibrous insulation attached to the first substantially-flat exterior surface, wherein outward-facing surfaces of the blocks form at least a first portion of an aerodynamic shape, and wherein the aerodynamic shape is continuous from an edge of a first one of the first plurality of blocks to an adjacent edge of a second one of the first plurality of blocks; and
a second plurality of blocks of rigid fibrous insulation attached to the second substantially-flat exterior surface, wherein one of inward-facing surfaces and sides of the at least one of the second plurality of blocks are in facing relationships with respective sides of at least one of the first plurality of blocks, wherein outward-facing surfaces of the second plurality of blocks form at least a second portion of the aerodynamic shape, wherein the aerodynamic shape is continuous from an edge of a first one of the second plurality of blocks to an adjacent edge of a second one of the second plurality of blocks, and wherein the aerodynamic shape is continuous from the first plurality of blocks to adjacent ones of the second plurality of blocks.

2. The aerodynamic surface of claim 1 , wherein outward-facing surfaces of the plurality of blocks are uniformly coated with a cured slurry, wherein the cured slurry comprises ceramic particles suspended in a colloidal solution.

3. The aerodynamic surface of claim 1 , wherein the first substantially-flat exterior surface comprises a strain isolation pad, and wherein the plurality of blocks of rigid fibrous insulation are attached to the strain isolation pad.

4. The aerodynamic surface of claim 1 , wherein the aerodynamic shape forms at least a portion of a leading edge of an airfoil.

5. The aerodynamic surface of claim 1 , wherein the aerodynamic shape forms at least a portion of a nose cone of a fuselage.

6. The aerodynamic surface of claim 1 , wherein the aerodynamic surface forms at least a portion of a wing-to-body fairing for a vehicle.

7. A vehicle, comprising:
a structure that comprises a first substantially-flat exterior surface and a second substantially-flat exterior surface, wherein the first and second substantially-flat exterior surfaces intersect at an angle;
a first plurality of blocks of rigid fibrous insulation attached to the first substantially-flat exterior surface, wherein outward-facing surfaces of the blocks form at least a first portion of an aerodynamic shape for the vehicle, and wherein the aerodynamic shape is continuous from an edge of a first one of the first plurality of blocks to an adjacent edge of a second one of the first plurality of blocks; and
a second plurality of blocks of rigid fibrous insulation attached to the second substantially-flat exterior surface, wherein one of inward-facing surfaces and sides of the at least one of the second plurality of blocks are in facing relationships with respective sides of at least one of the first plurality of blocks, wherein outward-facing surfaces of the second plurality of blocks form at least a second portion of the aerodynamic shape, wherein the aerodynamic shape is continuous from an edge of a first one of the second plurality of blocks to an adjacent edge of a second one of the second plurality of blocks, and wherein the aerodynamic shape is continuous from the first plurality of blocks to adjacent ones of the second plurality of blocks.

8. The vehicle of claim 7 , wherein outward-facing surfaces of the plurality of blocks are uniformly coated with cured slurry, wherein the cured slurry comprises ceramic particles suspended in a colloidal solution.

9. The vehicle of claim 7 , wherein the aerodynamic shape forms at least a portion of a wing for the vehicle.
