Abstract
Abstract An aircraft arresting means comprising a barrier net composed of horizontal bands joined by a plurality of vertical bands, the net having band ends which include loops that pass around pins forming part of a coupling to brakes to which ends of the bands are connected. The loops sliding around the pins cause adjustment of the net, when contacted by an aircraft so that a uniformly distributed load is obtained on all of the activated bands of the net.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
153 words
An arresting device for delta wing aircraft comprising: a. two parallel nets suspended horizontally across and above the runway for successively engaging the leading edge of the aircraft wing; b. each of said nets comprising an upper rope member and a lower rope member spaced from one another in a horizontal plane a distance which is equal to the height of the net; c. the upper rope members being joined at their ends and connected to common suspension means; d. the upper and lower rope members of each of said nets being interconnected by means of a plurality of spaced bands extending vertically between said rope members; e. the upper and lower rope members of each of said nets also being connected at their ends by means of a loop member slidably engaging a coupling member; f. said coupling member being connected to torque absorbing means arranged at opposite sides of the runway.
