CRANE-99999
Explosive foil initiators are generally difficult to operate at elevated temperatures because these systems are prone to expand longitudinally, shortening the length of the barrel and making the flyer ductile.

Naval Surface Warfare Center, Crane Division (NSWC Crane), has developed and patented an explosive foil initiator that provides triggering capacity without expanding since it is composed of a material that exhibits less than 10 percent increase in ductility at 200°C.

Advantages:
-Connectable to a firing cable
-Comprised of high temperature thermally compliant material
-The energy to fire the detonator is low
-The explosive can be pressed to higher density

Potential Applications:
-Military
