专利汇可以提供Covered cross runway channel for aircraft arresting system专利检索，专利查询，专利分析的服务。并且A row of covered channels are installed within an airport runway under a cross runway pendant and between a series of pitted pendant supporting and retaining devices. The lids of the channels are aligned with the surface of the runway and have depressed grooves for receiving the pendant when it is pushed down under the wheels of an overrunning aircraft. The connected channels conduct water through them and from interposed pit boxes off the runway into drains. Flanges at the ends of the channels connect them to apertured walls of the pit boxes. Heaters in the channels adjacent the grooves maintain them free of ice. Elastomeric slabs of a material, such as polyurethane, having a low coefficient of restitution may cover the lids to help damp wave motion and vibration of the pendant. The lids also absorb and resist the damaging impact. A V-shaped groove facilitates fabrication and operation, and the elastomeric slab as well as the lid under it are removable to facilitate replacement and access to the interior of the channels for maintenance.，下面是Covered cross runway channel for aircraft arresting system专利的具体信息内容。

权利要求

1. A covered cross runway channel for iNstallation under a cross runway pendant of an aircraft arresting system comprising an elongated channel having open ends for installation within an airport runway under said pendant, a removable lid on said channel, a pendant-receiving groove in said lid, said open ends of said elongated channel facilitating drainage through said elongated channel, and an elastomeric slab of material being disposed upon said lid for absorbing wave motion and vibration of said pendant.

2. A cross runway installation for an aircraft arresting system having a cross runway pendant deployed across said runway comprising a row of elongated covered channels as set forth in claim 1, said row of elongated channels being installed in a slot within said runway under said deployed pendant, said lids of said elongated channels being substantially aligned with the surface of said runway, said grooves being disposed below said runway surface for receiving said pendant and avoiding the wheels of overrunning aircraft, said ends of adjacent channels communicating with each other, the outer end channels in said row being lower than centrally disposed channels for causing any water in said channels to drain to the sides of said runway, drains at the sides of said runway adjacent the outer end channels of said row, and said outer end channels communicating with said drains for draining any water in said row of channels into said drains.

3. An installation as set forth in claim 2 wherein elastomeric material has a low coefficient of restitution whereby said wave motion and vibration are damped.

4. An installation as forth in claim 3 wherein said elastomeric material comprises polyurethane having a low resilience and high abrasion resistance.

5. An installation as set forth in claim 4 wherein said polyurethane has a resilience (Bashore) ranging approximately from 6 to 10%.

6. An installation as set forth in claim 2 wherein said groove is V-shaped.

7. A channel as set forth in claim 1 wherein said elastomeric material has a low coefficient of restitution whereby said wave motion and vibration are damped.

8. A channel as set forth in claim 7 wherein said elastomeric material comprises polyurethane having low resilience and high abrasion resistance.

9. A channel as set forth in claim 8 wherein said polyurethane has a resilience (Bashore) ranging approximately from 6 to 10%.

10. A channel as set forth in claim 1 wherein said groove is V-shaped.

11. A channel as set forth in claim 1 wherein flanges are disposed on said open ends to provide a means for connecting said channel to another said channel.

12. A cross runway installation for an aircraft arresting system having a cross runway pendant deployed across said runway comprising a row of elongated covered channels, said elongated channels having open ends for installation within an airport runway under said pendant, a removable lid on said channels, a pendant-receiving groove in said lid, said open ends of said elongated channels facilitating drainage through said elongated channels, said row of elongated channels being installed in a slot within said runway under said deployed pendant, said lids of said elongated channels being substantially aligned with the surface of said runway, said grooves being disposed below said runway surface for receiving said pendant and avoiding the wheels of overrunning aircraft, said ends of adjacent channels communicating with each other, the outer end channels in said row being lower than centrally disposed channels for causing any water in said channels to drain to the sides of said runway, drains at the sides of said runway adjacent the outer end channels of said row, and said outer end channels communicating with said drains for draining any water in said row of channels into said drains.

13. An installation as set forth in claim 12 wherein at least one pit is interposed in said runway within said row of elongated channels, said pit containing a portion of Said aircraft arresting system, apertures in said pits in line with said row of channels and said open ends of said channels adjacent said pit being connected to said pit at said apertures for draining water from it.

14. An installation as set forth in claim 13 wherein a pendant supporting and retaining device is disposed in said pit.

15. An installation as set forth in claim 14 wherein a number of said pendant supporting and retaining devices and pits are disposed across said runway and interposed within said row of elongated channels.

16. An installation as set forth in claim 15 wherein heaters are disposed in said channels adjacent said grooves for maintaining said grooves free of ice.

17. An installation as set forth in claim 16 wherein a pair of elongated heaters are mounted on upper portions of said side walls of each of said channels on both sides of said groove.
