FEASIBILITY STUDY OF AN EXPLOSIVELY ACTUATED FLASH PROTECTION DEVICE,
Abstract
A study was conducted of an explosively actuated optical shutter which would be compatible with a flash protection system. The shutter was to close an optical aperture 6-3/4 in. long by 2-1/4 in. high within a time interval of 480 microseconds. A design was made and two working models and ten shutters were fabricated. A search for the quickest acting detonator was made and resulted in the use of the T20E1 detonator. Preliminary tests were conducted and high speed motion pictures recorded the time and function on film. These tests indicated that a redesigned shutter and housing were required because of structural inadequacies. The next series of tests was conducted with the redesigned shutter and housing. In these tests, the explosive charge was increased in order to attain the specified time. Satisfactory performance was obtained in these tests. (Author)
