Abstract

A webbing system is disclosed for use as an aircraft barricade wherein a rality of rectangularly-shaped engaging loops are arranged in an alternating, multi-planar array and suspended across a landing area in the path of an approaching aircraft upon an assembly of support loops stretched between a pair of stanchions and connected on either side to an energy absorbing device. Slidably connected along upper and lower horizontal components of the support loops, the engaging loops are free to move laterally along the support loops toward the longitudinal axis of the aircraft when penetrated by the fuselage so that the aircraft is ensnared about its wings by the loops with equalized loading and its forward motion arrested.

Claims

1. A webbing system for arresting the forward motion of a landing aircraft comprising:

a plurality of first rectangular loops juxtaposed in substantially parallel planes and adapted to be extended substantially vertically across the path of the aircraft; and

a plurality of second rectangular loops arranged within said first rectangular loops in alternating transverse rows substantially coplanar with the respective planes of said first loops, said second loops being slidably connected to respective ones of said first loops to permit a lateral movement along the entire length thereof and equalize loading on the aircraft'"'"'s wings, said second loops furthermore positioned side-by-side in the transverse rows, those in alternate rows being substantially aligned with each other and those in adjacent rows being laterally offset from each other by approximately one-half the width of said loops.

2. A webbing system according to claim 1, wherein:

said second loops are formed to coextend with the vertical elevation of said first loops.

3. A webbing system according to claim 2, wherein:

each of said first and second loops comprises a relatively strong, flexible webbing material.

4. A webbing system according to claim 3, wherein said webbing material comprises nylon.

5. A webbing system according to claim 4, wherein:

said first loops are coated with a relatively thin layer of polyurethane to increase abrasion resistance and prevent tearing; and

said second loops are edged with a U-shaped polyurethane-coated nylon material.

6. An aircraft barricade, comprising:

a plurality of first rectangular loops juxtaposed in substantially parallel planes;

support means releasably connected to said first rectangular loops for extending said first loops substantially vertically across a projected path of an incoming aircraft;

energy absorber means connected to said first rectangular loops for applying substantially horizontal restraint forces to said loops; and

a plurality of second rectangular loops arranged within said first rectangular loops in an alternating multi-planar array, said second loops being substantially disposed within respective planes of said first loops and slidably connected thereto to permit lateral movement along the entire width thereof and equalize loading on the aircraft wings, said second loops furthermore positioned side-by-side, alternated in transverse rows substantially coplanar with the respective planes of said first loops, substantially aligned with each other in alternate transverse rows, and laterally offset from each other in adjacent transverse rows by approximately one-half the width of said loops.

7. An aircraft barricade according to claim 6, wherein:

said second loops are formed to coextend with the vertical elevation of said first loops.

8. An aircraft barricade according to claim 7, wherein said energy absorber means comprises:

a pair of energy absorbers located on either side of the projected path of the incoming aircraft; and

lengths of cable engaging said energy absorbers and connected to the respective sides of said first loops near the middle thereof.

9. An aircraft barricade according to claim 7, wherein said support means comprises:

a pair of stanchions located on either side of the projected path of the incoming aircraft;

releasable strap members connected to the four corners of said first loops and mounted upon said stanchions to apply tension along the upper and lower horizontal components of said first loops; and

adjustable means for mounting said strap members upon said stanchions.

10. An aircraft barricade according to claim 7, wherein:

each of said first and second loops comprise a relatively strong, flexible webbing material.

11. An aircraft barricade according to claim 10, wherein said webbing material comprises nylon.

12. An aircraft barricade according to claim 11, wherein:

said first loops are coated with a relatively thin layer of polyurethane to increase abrasion resistance and prevent tearing; and

said second loops are edged with a U-shaped polyurethane-coated nylon material.
