ABSTRACT
The Air Force Research Laboratory's Directed Energy Directorate has developed a fast closing shutter for the purpose of explosive debris mitigation. The shutter forms a high vaccum seal in 15 μs by the plastic deformation and pinching off of an 8 mm inside diameter profiled cartridge brass tube by two explosively propelled Ti slugs impacting from opposite directions. Two explosive detonators, the tube itself, and steel disks which back the Ti slugs are the only sacrificial parts. Design and performance details, the developmental history, scaling issues, and advantages over other shutter designs are discussed. © 2000 American Institute of Physics.
