摘要

The burning rate behavior of a propellant is an important parameter in analytical modeling of the combustion in rockets and guns. Empirical burning rate data are usually obtained from tests using the standard (Crawford) strand-burner, where a rod or strand of propellant is burned from one end to the other. The pressure in the bomb chamber and the time between two wires are measured. The report describes a modified test equipment, controlled by a personal computer with an analog and digital input-output (I/O)-board from Data Translation Inc. Calibration, tests and evaluation are made with the same, textwindow controlled computer code. The burning rate-pressure relationship is calculated and the results plotted on log-log paper.
