Filed:

Oct 12, 2000

Appl. No.:

09/689100

Inventors:

David K. Colarik - Media PA
Thomas L. Quinn - Cochranville PA

Assignee:

Engineered Arresting Systems Corporation - Aston PA

International Classification:

B64F 102

US Classification:

244110C

Abstract:

A hook cable support assembly is arranged to support a hook cable above a runway surface for arrestment of an aircraft having a tail hook. The operating mechanism of the support assembly is mounted to the detachable cover of an enclosure. A cable support block holding the hook cable can be rotated to lower the cable into a runway slot for non-arrested landings and can be depressed downward upon impact by an aircraft wheel. Support block rotation is controlled by a pneumatic cylinder and compression spring combination acting via a four-bar linkage. Support block upward recovery following depression is controlled by torsion springs. The cylinder and compression and torsion springs are mounted to the lower surface of the cover and function as a self-contained mechanism isolated from mechanical contact with the enclosure. With this cover-mounted configuration, the operating mechanism of the cable support assembly is removable for service or replacement by detachment of the cover.

David K. Colarik - Media PA

Assignee:

International Classification:

B64F 100

US Classification:

244110C, 244110 R, 256 125, 256 1

Abstract:

Anchoring systems for aircraft arresting nets utilize frangible anchor links around lower horizontal straps of each net element of a composite arresting net. Each anchor link may be formed from flexible plastic sheet material, with openings through which an anchor cable passes and is secured to a runway surface by an anchor retainer. The anchor links provide ease of anchoring system assembly in the field and retain the bottom of the arresting net in proper position prior to engagement of the arresting net by an aircraft overrunning the runway. When an aircraft engages the net, the anchor links break to permit the net to conform to and safely stop the aircraft. Each anchor link may be perforated in its central portion or otherwise formed or specified to provide suitable frangibility in an arresting incident.

Abstract:

An elemental net for a multiple element aircraft arresting net system. The elemental net has a single upper horizontal strap, several vertical straps having top ends and bottom ends, and at least two lower horizontal straps. The top ends of the vertical straps are directly affixed to the upper horizontal strap at spaced intervals along the upper horizontal strap. The bottom ends of the vertical straps are alternatingly affixed to one of the lower horizontal straps so that the lower horizontal straps are free to move relative to each other to a significant degree and so that lifting of one vertical strap will tend to lift only one of the lower horizontal straps in the vicinity of the vertical strap being lifted. The present invention provides a variable window which is free to expand or contract during aircraft engagement, permitting easier penetration of the net by a greater mix of aircraft. The present invention also ensures that only one lower horizontal strap of the elemental net will seat on the nosewheel strut, while at least one lower horizontal is free to move longitudinally under the nosewheel strut to apply arresting force.
