Abstract

A net deployment system which, in one example, includes a manifold assembly including multiple weight ducts and a bladder port. A weight is disposed in each weight duct and each weight is tied to the net. A bladder is behind the net and is over the bladder port. At least one inflator charge is associated with the manifold for inflating the bladder and firing the weights out of the weight ducts to deploy the net in the path of an incoming threat.

Claims

1. A net deployment system comprising:

a net;

a manifold assembly including multiple weight ducts and a bladder port;

a weight in each weight duct, each weight tied to the net;

a bladder behind the net and over the bladder port; and

at least one inflator charge associated with the manifold assembly for inflating the bladder and firing the weights out of the weight ducts to deploy the net in the path of an incoming threat.

2. The net deployment system of claim 1 in which the manifold assembly has a central fitting including the bladder port and the weight ducts extend outwardly therefrom.

3. The net deployment system of claim 2 in which the manifold assembly further includes opposing inflator charge plenums extending outwardly from the central fitting and there is at least one inflator charge in each plenum.

4. The net deployment system of claim 3 in which there is an inflator charge plenum between each pair of weight ducts.

5. The net deployment system of claim 1 in which the weights are made of foam.

6. The net deployment system of claim 1 in which the net has four corners and there is a weight tied to each corner of the net.

7. The net deployment system of claim 1 in which the bladder includes a broad flat top and a side wall terminating in a flange securable over the bladder port.

8. The net deployment system of claim 7 in which the net is folded on the broad flat top of the bladder.

9. The net deployment system of claim 1 in which the net is square and between 2-3 m on a side.

10. The net deployment system of claim 1 in which the net is between 30 and 60 mm mesh.

11. A net deployment system comprising:

a net;

a manifold assembly including;

a central fitting including a bladder port,

weight ducts extending outwardly from the central fitting, and

at least one inflator charge plenum;

a weight in each weight duct, each weight tied to the net;

a bladder behind the net and over the bladder port; and

at least one inflator charge in the plenum for inflating the bladder and firing the weights out of the weight ducts to deploy the net in the path of an incoming threat.

12. The net deployment system of claim 11 in which the manifold assembly includes opposing inflator charge plenums extending outwardly from the central fitting and there is at least one inflator charge in each plenum.

13. The net deployment system of claim 12 in which the at least one inflator charge plenum is an inflator charge plenum between each pair of weight ducts.

14. The net deployment system of claim 11 in which the weights are made of foam.

15. The net deployment system of claim 11 in which the net has four corners and there is a weight tied to each corner of the net.

16. The net deployment system of claim 11 in which the bladder includes a broad flat top and a side wall terminating in a flange securable over the bladder port.

17. The net deployment system of claim 16 in which the net is folded on the broad flat top of the bladder.

18. The net deployment system of claim 11 in which the net is square and between 2-3 m on a side.

19. The net deployment system of claim 11 in which the net is between 30 and 60 mm mesh.
