A STUDY OF THE FUNDAMENTALS OF LIQUID PROPELLANT SENSITIVITY
Abstract
Preliminary sensitivity tests of lead azide samples, with initial temperatures to -170 C, were performed in the new cryogenic IITRI shocktube facility. Detonations were generally identified within 200 microseconds of the time that incident Mach 2.6 nitrogen shocks were reflected from the surface of the sample. Two characteristic induction periods were noted. The first period can be considered typical. The second period exhibited an increasing light output which stabilizes. Subsequent light output jumps instantaneously and work output follows within 10-20 microseconds. An appreciable sensitivity increase was identified with traces of air (oxygen) in the driven gas and lowered initial azide sample temperatures of 200 C; at otherwise constant conditions time delays decreased by factors of 10 and 2.
