Abstract
A method of slowing an aircraft overrunning a runway, including paving an area immediately beyond the end of a runway with foamed glass bodies to define a bed, covering the bed with a layer of cementitious material to define a composite bed, and crushing at least a portion of the composite bed with an oncoming aircraft, wherein crushing the at least a portion of the composite bed removes kinetic energy from the oncoming aircraft to slow the oncoming aircraft. The composite bed is generally resistant to fire.
Claims18
A method of slowing an aircraft overrunning a runway, comprising:
- a) paving an area with foamed vitreous bodies having a crushing failure mode to define a bed;
- b) covering the bed with a layer of cementitious material to yield a composite bed having foamed vitreous bodies having a crushing failure mode in a cementitious matrix having a crushing failure mode covered by a top layer of cementitious material;
- and
- c) crushing at least a portion of the composite bed with an oncoming aircraft;
- wherein the composite bed is at least 85 percent foamed vitreous bodies;
- wherein the composite bed has a cementitious surface;
- and
- wherein the foamed vitreous bodies have a closed pore structure.
A method of slowing an aircraft overrunning a runway, comprising:
- a) establishing an aircraft arrestor bed adjacent a runway, wherein the aircraft arrestor bed is formed from a paving layer to define a top solid cementitious layer immediately adjacent a concrete composite layer of closed-cell foamed glass aggregate in a cementitious matrix;
- b) moving an aircraft over the aircraft arrestor bed;
- and
- c) crushing at least a portion of the arrestor bed with the aircraft;
- and
- d) slowing the oncoming aircraft;
- wherein the arrestor bed is has a crushing failure mode.
A method of slowing an aircraft overrunning a runway, comprising:
- a) establishing an aircraft arrestor bed adjacent a runway, wherein the aircraft arrestor bed is formed from a paving layer defining a solid surface paving material covering a concrete of porous foamed glass aggregate bodies suspended in a paving material matrix;
- b) piloting an oncoming aircraft onto the aircraft arrestor bed;
- c) removing kinetic energy from the oncoming aircraft by crushing at least a portion of the arrestor bed under the weight of the oncoming aircraft;
- and
- d) stopping the oncoming aircraft;
- wherein the arrestor bed is has a crushing failure mode.
