Protective cover for aircraft pitot probes

1. A protective cover for a pilot probe of an aircraft comprising:

a first tubular member formed of a rigid material; and

a second tubular member formed of a flexible material including a first ply disposed on an inner side of said first tubular member, having an opening at a first end thereof for receiving the leading end of a pilot probe therein and a closed second end thereof, and a second ply disposed on an outer side of said first tubular member, having a first end thereof secured about said first end of said inner ply and a second end thereof secured to said second end of said first ply.

2. The cover of claim 1 including a member secured to at least one of said second ends of said plies which may be gripped and pulled to remove said cover mounted on a pilot probe.

3. The cover of claim 1 including a banner secured to at least one of said second ends of said plies bearing instructions for removal of said cover prior to take-off.

4. The cover of claim 1 wherein said first tubular member has a length shorter than the length of the space between said plies.

5. The cover of claim 1 wherein said first tubular member includes an appendage projecting from an end thereof secured to at least one of said second ends of said plies.

6. The cover of claim 5 wherein said appendage includes an opening therethrough accommodating a portion of said second end of said first ply.

7. The cover of claim 1 wherein said first tubular member includes at least one frusto-conically configured inner surface accommodating receipt of the leading end of a pilot probe upon applying said cover thereon.

8. The cover of claim 1 wherein said first tubular member is formed of a high temperature. flame retardant material.

9. The cover of claim 1 wherein said first tubular member is formed of silicone.

10. The cover of claim 1 wherein a portion of at least one first end portion of a ply of said second tubular member is configured to form an entry into said opening which receives a pilot probe, providing an interference fit with a probe received therein.

11. The cover of claim 10 wherein said configured portion of said ply is provided with an O-ring formed of an elastomeric material.

12. The cover of claim 1 wherein said second tubular member is formed of a woven material.

13. The cover of claim 12 wherein said woven material is braided.

14. The cover of claim 1 wherein said second tubular member is formed of braided glass fiber threads.

15. The cover of claim 1 wherein said second tubular member is formed of braided para-aramid fibers.

16. A protective cover for a pilot probe of an aircraft comprising:

a first tubular member formed of a rigid material; and

a second tubular member funned of a flexible material including a first segment extending through said first tubular member forming an inner ply providing an opening therethrough having free and integral ends, and a second segment inverted relative to said first segment, extending along an outer side of said first tubular member and said first segment thereof, forming an outer ply provided with integral and free ends,

wherein the integral ends of said segments of said second tubular member are secured together to provide a closure at one end of said opening and the free ends of said segments are secured together to provide an entry opening for receiving the leading end of a probe into said closed opening.

17. The cover of claim 16 wherein said first tubular member has a length shorter than length of said plies.

18. The cover of claim 17 wherein said first tubular member is disposed adjacent a closed end of said opening.

19. The cover of claim 18 wherein said first tubular includes a longitudinally projecting appendage interleaved with and secured to the integral ends of said segments of said second tubular member.

20. The cover of claim 19 wherein said appendage includes an opening therethrough through which at least the integral portion of said first segment extends.

21. The cover of claim 16 wherein the free ends of said segments are inverted with the inverted portions thereof being secured together.

22. The cover of claim 21 including an O-ring formed of an elastomeric material being encompassed by a portion of at least one of said free ends of said segments providing an opening therethrough for receiving and engaging a portion of a pilot probe with an interference fit.

23. The cover of claim 16 wherein an inner surface of said first tubular member is provided with at least one frusto-conically configured surface accommodating the receipt of a pilot probe in said opening.

24. The cover of claim 16 wherein said first tubular member is formed of a high temperature, flame retarded material.

25. The cover of claim 16 wherein said first tubular member is formed of silicone.

26. The cover of claim 16 wherein said second tubular member is formed of a woven material.

27. The cover of claim 26 wherein said woven material is braided.

28. The cover of claim 16 wherein said second tubular material is formed of braided glass fiber threads.

29. The cover of claim 16 wherein said second tubular member is formed of braided para-aramid fiber.

30. The cover of claim 16 including a looped member secured to the integral ends of said sections which may be gripped for removal of said cover from a pilot probe.
