Abstract
A system for arresting movement of an aircraft traveling off the end of a runway at high speeds. Rigid, friable, fire resistant foam boards, preferably phenolic foam, are connected to form a panel, and a plurality of layers comprised of stacked panels are adhered to a base surface. The panels are formed from unfaced foam boards, the compressive strength of the stack of boards being less than the force exerted by the landing gear of the aircraft to allow the boards to be crushed by the landing gear.

An aircraft arresting system, comprising:
- an aircraft arresting area adjacent an end of an aircraft runway;
- the aircraft arresting area being comprised of a plurality of vertically stacked layers of preformed rigid, friable, fire resistant foam;
- thereby permitting the height of the arresting area to be varied by removing or adding any number of the vertically stacked layers of foam;
- the layers of foam being adhered to each other by adhesive, with the lowermost layer of foam being adhered to a support surface;
- the compressive resistance of the combined layers of rigid foam being less than the force exerted by the landing gear of an aircraft of the type to be arrested when moving into the arresting area from the runway, and the layers of rigid foam being comprised of a plurality of unfaced rigid foam boards so that the foam is crushed when contacted by the landing gear.
A method of assisting to arrest an aircraft moving over an end of an aircraft runway, comprising the steps of:
- adhering a plurality of vertically stacked layers of preformed rigid, friable fire resistant foam to each other and to a base support adjacent the end of the runway to form an aircraft arresting area thereby permitting the height of the arresting area to be varied by removing or adding any number of the vertically stacked layers of foam;
- the compressive strength of the combined layers of rigid foam being less than the force exerted by the landing gear of an aircraft of the type to be arrested when moving into the arresting area from the runway, the layers of rigid foam being comprised of a plurality of unfaced rigid foam boards so that the foam is crushed when contacted by the landing gear and
- the boards in one layer being adhered to the boards in adjacent layers by adhesive.
