Abstract

A method of sealing a gap between first and second aerodynamic surfaces. The width of the gap between the two surfaces is measured to obtain a gap measurement. The width of a seal member is pre-formed in accordance with the gap measurement. The seal member is fitted into the gap such that the seal member is substantially flush with the first and second aerodynamic surfaces. Apparatus for performing the method is also described. The apparatus comprising: a metrology device adapted to measure the width of the gap between the first and second aerodynamic surfaces; a seal member dispenser for dispensing a seal member; and a cutter adapted to cut the seal member to size in accordance with the measurements obtained by the metrology device.

Claims

1. A method of sealing a gap between first and second aerodynamic surfaces, the method comprising:

measuring the width of the gap between the two surfaces to obtain a gap measurement;

pre-forming the width of a seal member in accordance with the gap measurement; and

fitting the seal member into the gap such that the seal member is substantially flush with the first and second aerodynamic surfaces.

2. The method of claim 1 further comprising measuring the width of the gap at a plurality of positions along its length and forming the width of the seal member accordingly.

3. The method of claim 1 wherein the method further comprising:

forming a recess in a corner where a first one of the aerodynamic surfaces meets the gap, the recess having a seat which is inset relative to the first one of the aerodynamic surfaces; and

engaging the seal member with the seat.

4. The method of claim 3 wherein the method further comprising:

forming a second recess in a corner where a second one of the aerodynamic surfaces meets the gap, the second recess having a second seat which is inset relative to the second one of the aerodynamic surfaces; and

engaging the seal member with the second seat.

5. The method of claim 3 further comprising bonding the seal member to the seat(s) with an adhesive.

6. The method of claim 3 wherein the (or each) recess is formed by removing material.

7. The method of claim 1 wherein the seal member comprises a curable material which is at least partially cured before sealing the gap.

8. The method of claim 1 wherein the width of the sealing member is pre-formed by removing material from the sealing member.

9. The method of claim 1 further comprising dispensing the seal member from a roll, and cutting the seal member to size in accordance with the gap measurement as it is dispensed from the roll.

10. Apparatus for performing the method of claim 1, the apparatus comprising:

a. a metrology device adapted to measure the width of the gap between the first and second aerodynamic surfaces;

b. a seal member dispenser for dispensing a seal member; and

c. a cutter adapted to cut the seal member to size in accordance with the measurements obtained by the metrology device.

11. The apparatus of claim 10 further comprising:

an adhesive applicator.

12. The apparatus of claim 10 wherein the seal member dispenser comprises a roll on which the seal member is wound.

13. An aerodynamic assembly comprising:

first and second components with respective first and second aerodynamic surfaces, the first and second components having opposed edges;

a gap between the first and second aerodynamic surfaces; and

a seal member which extends between the aerodynamic surfaces to seal the gap and is substantially flush with the aerodynamic surfaces, wherein at least one of the components has a recess which is formed in a corner where a respective one of the aerodynamic surfaces meets a respective one of the opposed edges, the recess having a seat which is inset relative to its respective aerodynamic surface and engages the seal member; and

wherein the width of the gap varies along its length and the width of the seal member varies accordingly.

14. The assembly of claim 13 wherein the or each seat is substantially parallel with its respective aerodynamic surfaces.

15. The assembly of claim 13 further comprising an adhesive bonding the seal member to the or each seat.

16. The assembly of claim 13 wherein the components are coupled to each other by a fastener which extends through the seat.

17. The assembly of claim 13 wherein each component has a recess which is formed in a corner where a respective one of the aerodynamic surfaces meets a respective one of the opposed edges, each recess having a seat which is inset relative to its respective aerodynamic surface and engages the seal member.
