Abstract
ABSTRACT This paper deSCribeS the photoinstrumentation employed to record the blast and fragmentation effects on a warship resulting from the on-board detonation of various explosive warheads. Details are presented of cameras, cameraprotection, lighting and associated instrumentation that were used in this harsh environment Good quality resultswere obtained which provided scientists with a much better understanding of the damage processes involved. In particular the flashbulb lighting and camera protection equipment developed for the trial proved yew successful.Keywords: high speed photography, camera protection, flashbulb illumination, ship vulnerability, explosive blast. 1. INTRODUCTION In 1994 the Royal Australian Navy (RAN) and the Australian Defence Science and Technology Organisation (DSTO)conducted experiments on-board the decommissioned destroyer escort Derwent to assess its vulnerability to a variety ofconventional explosive warheads. These experiments were the culmination of a program of work to study the effects ofblast and fragment attack on ship's structures (Fig. 1) which also included small-scale and full-scale experiments onsimulated ship's compartments. In all the experiments high-speed photography was pivotal in recording these effects
