| Abstract: |
| To further investigate the insensitive gun propellants, the progresses of study on test technology and damage effect characteristics assessment of propellants were systematically reviewed from large-scale insensitive property test, laboratory sensitivity assessment test and small-scale simulation test and assessment for gun propellants. The paper mainly described the means and methods of small analog detection with the characteristics of propellant, such as hot fragment conductive ignition test, small scale slow cook-off experiment equipment test, and critical diameter test. The development direction for test and evaluation of insensitive propellant was put forward. Small-scale simulation test and evaluation technology of propellant were studied. This kind of method can study the law and mechanism of the influence of propellant composition and grain type on the sensitivity of propellant, and is expected to reduce or replace full-size propellant loading test; develop test methods, reaction criteria and evaluation criteria and evaluation criteria applicable to porous discrete structure of propellant, so an to promote the research and application of high-energy insensitive propellant; develop the technology for evaluating the impact of propellant charge on the survivability of ammunition, and study the influence law of charging structure on the reaction level of typical ammunition. |
