Protective cover for a pitot probe
A protective cover mountable on a pitot prob disposed on the fuselage of an idle aircraft adapted to be tailored to similar covers mountable on other probes of such aircraft, including a tubular body of a braided fabric material provided with a recess therein for receiving the leading end of a pitot tube therein, a first annular member disposed in such recess adjacent an open end thereof having a portion of the tubular body projecting therethrough, including such member therein and a second annular member disposed substantially coaxially with such first annular member and secured to such tubular body of braided fabric material, having at least one tab provided on the exterior thereof provided with means to tether such cover to similar covers.
1. A protective cover mountable on a pitot probe disposed on the fuselage of an idle aircraft, adapted to be tethered to similar covers mountable on other probes of said aircraft, comprising:
a tubular body of a braided fabric material provided with recess therein for receiving the leading end of a pitot probe therein;
a first annular member disposed in said recess adjacent an open end thereof, having a portion of said tubular body projecting therethrough, including said first annular member therein; and
a second annular member disposed substantially coaxially relative to said first annular member and secured to said tubular body of braided fabric material, having at least one tab provided on the exterior thereof provided with means to tether such cover to similar covers.
2. The cover of claim 1 wherein said tubular member is formed of a high temperature, flame retardant material.
3. The cover of claim 1 wherein said tubular member is formed of braided glass fiber threads.
4. The cover of claim 1 wherein said tubular member is formed of braided para-aramid fibers.
5. The cover of claim 1 wherein said first annular member is formed of a material providing an interference fit with a probe inserted therein.
6. The cover of claim 5 wherein said first annular member comprises an o-ring formed of an elastomeric material.
7. The cover of claim 1 wherein said second annular member is encapsulated on said tubular member.
8. The cover of claim 1 wherein said second annular member is formed of a silicone rubber material.
9. The cover of claim 1 wherein said tab projects radially relative to a centerline of said second annular member.
10. The cover of claim 9 wherein said tab is provided with an opening for receiving therethrough and attaching a cord.
11. The cover of claim 1 including a pair of tabs provided on said second annular member, projecting laterally and lying in a plane including the axis of said second annular member.
12. The cover of claim 11 wherein each of said tabs is provided with an opening therethrough through which a cord may extend and be secured thereto.
13. The cover of claim 1 wherein the ends of said tubular member are hemmed and stitched together, precluding exposure of frayed ends thereof.
14. The cover of claim 1 wherein one end of said tubular member is hemmed, flattened and stitched together to form said closed end.
15. The cover of claim 14 including a chord having the ends thereof received between hemmed portions of said tubular members stitched together, forming a loop which may be grasped and pulled for removing said cover mounted on a probe.
16. The cover of claim 7 wherein said second annular member is formed by infusing a liquid form of a liquid rubber component into an outer layer of said tubular body of braided fabric material, about the area thereof coinciding with said first annular member, in sufficient depth to infuse within the voids of said fabric material, placing said infused tubular body in a mold provided with an internal configuration in the shape of said second annular member, injecting additional liquid rubber compound into said mold in contact with said fused component, heating said mold and then heating said component to cure it and correspondingly form said second member encapsulating said tubular body of braided fabric material.
17. The cover of claim 16 wherein said tubular member is formed of braided glass fibers.
18. The cover of claim 16 wherein said tubular member is formed of braided para-aramid fibers.
19. The cover of claim 16 wherein said rubber compound comprises a silicone rubber material.
20. A protective cover mountable on a pitot probe disposed on the fuselage of an idle aircraft, adapted to be tethered to similar covers mountable on other probes of said aircraft, comprising:
a tubular body of a braided fabric material provided with recess therein for receiving the leading end of a pitot probe therein;
a first annular member disposed in said recess adjacent an open end thereof, having a portion of said tubular body projecting therethrough, including said first annular member therein; and
a second annular member disposed substantially coaxially relative to said first annular member and secured to said tubular body of braided fabric material, comprising a pair of tabs provided on said second annular member, projecting laterally and lying in a plane including the axis of said second annular member;
wherein each said tab projects radially relative to a centerline of said second annular member, wherein the tabs are integral to the second annular member on opposed sides of the exterior of the second annular member,
wherein each of said tabs is provided with an opening therethrough through which a cord may extend and be secured thereto;
wherein said first annular member comprises an o-ring formed of an elastomeric material;
wherein said second annular member is formed of a silicone rubber material.
