Paper Abstract

The acoustic environment created by turbulence in aircraft flight tests demands that illumination sources for high speed photography of munitions drops be extremely rugged. A repetitive pulsed surface discharge system has been developed to provide wide angle illumination in a bomb bay for photography at 250 - 500 Hertz. The lamp has a simple construction suitable for adverse environments and produces 100 mJ of visible light per pulse. The discharge parameters were selected to minimize the size and complexity of the power supply. The system is also capable of operating at high repetition rates; preliminary tests demonstrated 1000 pulses at 1 kHz, 200 pulses at 1.5 kHz, and 13 pulses at 2 kHz. A simple power supply capable of providing several amperes at 450 V is being completed; it will be used to extend the run times and to explore extensions to higher repetition rate.
