摘要
Abstract
A new evaluation method of dynamic strength of high energy propellants was proposed. Dynamic mechani-cal property of the propellants is characterized by the critical impact energy and the limit impact stress when the critical damage to the granular propellants by a dropping hammer occurs. Results indicate that the evaluation method can quantita-tively reflect the dynamic mechanical strength of the propellants. The critical impact energy of TEGDN propellant, nitra-mine propellant and nitroguanidine propellant is 18. 8 J/cm2,14. 2 J/cm2 and 3. 8 J/cm2,and the limit impact stress 247. 2 MPa,214. 2 MPa and 118. 5 MPa,respectively.关键词
