Abstract

This aircraft arrester net gear comprises at least one flexible frame having each at least one elementary net slidably mounted therein, in such a manner that when a forwardly projecting element of the aircraft engages the net the elementary nets can slide in relation to the frame and the horizontal width of the net mesh normally engaged by the aircraft wings is reduced; for this purpose, open-loop slack portions of the horizontal straps of the elementary nets are provided at each end thereof.

Claims

1. An aircraft arrester net gear comprising:

(i) a supporting frame consisting of

an upper horizontal strap connected at its ends to posts for raising the net and to braking means,

a lower horizontal strap connected at its ends to said braking means,

(ii) at least one elementary net slidingly mounted on said supporting frame, said at least one elementary net comprising;

an upper horizontal strap having slack at both ends,

a lower horizontal strap having slack at both ends,

vertical straps connecting said horizontal upper and lower straps of said at least one elementary net,

(iii) unbreakable connecting means rigid with the upper horizontal strap of the frame and presenting loops in which can slide the upper horizontal strap of the at least one elementary net,

unbreakable connecting means rigid with the lower horizontal strap of the frame and presenting loops in which can slide the lower horizontal strap of the at least one elementary net,

whereby when the arrester net gear is engaged by an aircraft said at least one elementary net can slide laterally, the vertical straps forming a net mesh and being brought nearer together by engagement with the aircraft thus permitting a greater spacing between the vertical straps of the net, and the whole arrester net gear following the aircraft and thus actuating the braking means through the upper horizontal strap of the frame as well as through the lower horizontal strap of the frame.

2. An aircraft arrester net gear, as claimed in claim 1, comprising a plurality of elementary nets slidingly mounted on the supporting frame.
