Studies on crack extension in solid propellant
摘要
Abstract
The research status of the crack extension in solid propellant at home and abroad are introduced. Experimental study and theoretical analysis of the crack extension in solid propellant are summarized. The advantages and disadvantages of such study are analyzed. The influences of various factors on crack extension in solid propellant are generalized. The results show that the tension ma- chine and high-speed photography are main means for studying the mechanics characteristic of pro- pellant with crack, and the combustion property of propellant and the extension of crack; the working pressure in combustion chamber, pressure boost rate, style and size of crack, and burning rate of pro- pellant arc the important factors for the crack extension in solid propellant. It is pointed out that it is necessary to research the quantitative relationship between various factors and crack extension.关键词
