INVESTIGATION OF CURRENT TECHNIQUES OF LOW ALTITUDE PYROTECHNIC FLASH NIGHT AERIAL RECONNAISSANCE PHOTOGRAPHY

Abstract

This analysis traces the development of the pyrotechnic flash night photographic system with special emphasis on its application and use in Naval reconnaissance aircraft. A program of mathematical analysis is described which includes the development of a graphical method of presenting the operational limits of the night photographic system. A correlation is made between flight test data and mathematical data which reveals that the widely accepted value of .09 foot-candle-seconds for minimum scene illumination is unrealistically low and that .135 f.c.s. is a more practical value. The advantages of upward cartridge ejection are fully substantiated. (Author)
