Abstract

An inflatable sealing assembly for sealing between an intake section of a turbine engine and an air inlet ring of a vehicle. The inflatable sealing assembly including a seal holder coupled to the intake section of the engine and having a first inflatable seal, a second inflatable seal, and a closed cell foam material disposed therein. The first inflatable seal and the second inflatable seal are configured when inflated to provide a seal between the intake section of the turbine engine and the air inlet ring of the vehicle and prevent foreign object debris and/or water from entering the turbine engine.

Claims (36)

1. A seal assembly for sealing between an engine and an air inlet of a vehicle, the engine having an inlet and the air inlet having an inner diameter and an outer diameter, the seal assembly comprising:

a seal holder configured for coupling to the inlet of the engine;

a first inflatable seal disposed within the seal holder;

a second inflatable seal disposed within the seal holder; and

a closed cell foam material disposed within the seal holder and contacting a face of the air inlet,

wherein the first inflatable seal and the second inflatable seal provide a seal when positioned and thereafter inflated about the inner diameter and the outer diameter of the air inlet of the vehicle.

2. The seal assembly of claim 1 , wherein the first inflatable seal and the second inflatable seal are formed of an elastomer material.

3. The seal assembly of claim 2 , wherein the elastomer material is a rubber material.

4. The seal assembly of claim 2 , wherein the elastomer material is a silicone material.

5. The seal assembly of claim 1 , wherein the first inflatable seal and the second inflatable seal are configured to retain their shape.

6. The seal assembly of claim 1 , wherein the closed cell foam material minimizes absorption of an engine fluid.

7. The seal assembly of claim 1 , wherein the closed cell foam material is substantially rectangular in form.

8. The seal assembly of claim 1 , wherein the closed cell foam material is substantially triangular in form.

9. The seal assembly of claim 1 , further including an air conduit in fluidic communication with the first inflatable seal, the second inflatable seal, an inflation air source and the engine.

10. The seal assembly of claim 9 , wherein the inflation air source is a pump, a compressed air source or the engine.

11. The seal assembly of claim 9 , wherein the air conduit is provided with at least one of a visual pressure indicator, a vent valve, a fill valve, and a check valve.

12. An inflatable sealing means for sealing between an intake section of a turbine engine and an air inlet ring of a vehicle, the inflatable sealing means comprising:

a seal holder configured for coupling to the intake section of the turbine engine;

a first inflatable seal formed of an elastomer material and disposed within the seal holder, adjacent an inner diameter of the air inlet ring;

a second inflatable seal formed of an elastomer material and disposed within the seal holder, adjacent an outer diameter of the air inlet ring; and

a closed cell foam material disposed within the seal holder and contacting a face of the air inlet ring,

wherein the first inflatable seal and the second inflatable seal when inflated provide a seal between the intake section of the turbine engine and the air inlet ring of the vehicle and prevent foreign object debris or water from entering the turbine engine.

13. The inflatable sealing means of claim 12 , wherein the elastomer material is a rubber material.

14. The inflatable sealing means of claim 12 , wherein the elastomer material is a silicone material.

15. The inflatable sealing means of claim 12 , wherein the first inflatable seal and the second inflatable seal are configured to retain their shape when deflated without the need for reinforcement.

16. The inflatable sealing means of claim 12 , further including an air conduit in fluidic communication with the first inflatable seal, the second inflatable seal, an inflation air source and the turbine engine.

17. The inflatable sealing means of claim 16 , wherein the inflation air source is at least one of a pump, a compressed air source or the turbine engine.

18. The inflatable sealing means of claim 16 , wherein the air conduit is provided with at least one of a visual pressure indicator, a vent valve, a fill valve, and a check valve.

19. An inflatable sealing means for sealing between an intake section of a turbine engine and an air inlet ring of a vehicle, the inflatable sealing means comprising:

a seal holder configured for coupling to the intake section of the turbine engine;

a first inflatable seal formed of an elastomer material and disposed within the seal holder, adjacent an inner diameter of the air inlet ring;

a second inflatable seal formed of an elastomer material and disposed within the seal holder, adjacent an outer diameter of the air inlet ring;

a closed cell foam material disposed within the seal holder and contacting a face of the air inlet ring; and

an air conduit in fluidic communication with the first inflatable seal for inflation thereof, the second inflatable seal for inflation thereof, an inflation air source and the turbine engine,

wherein the first inflatable seal and the second inflatable seal when inflated provide a seal between the intake section of the turbine engine and the air inlet ring of the vehicle and prevent foreign object debris or water from entering the turbine engine.

20. The inflatable sealing means of claim 19 , wherein the inflation air source is at least one of a pump, a compressed air source, or the turbine engine and the air conduit is provided with at least one of a visual pressure indicator, a vent valve, a fill valve, and a check valve.
