On the Measurements of Time of Flight of Bombs

Abstract

Calibration of the camera Clock of the Gauge Unit was undertaken for the purpose of determining time of flight measures for bombs accurate to plus or minus 0.003 second. Comparison with time of flight measures made by the Chronograph of the Vertical Camera Obscura was made by means of seven determinations of which three were secured simultaneously by both methods. The accuracy of the Chronograph method was tentatively examined.
