Closed bomb testing
WebAug 1, 1975 · An analysis of the closed bomb with certain simplifying assumptions is presented. This analysis is shown to satisfactorily predict the pressure history in the closed bomb. A propellant grain parameter sensitivity analysis is conducted to show the sensitivity of the pressure history and the muzzle velocity data. WebThe closed bomb test is a standard device used to measure gasification rates for energetic materials. Knowledge of propellant chemical formulation and geometry allows for calculation of a linear burn rate from the measured pressure versus time data. Performance is given in terms of relative quickness (RQ) and relative force (RF).

WebA closed bomb relative quickness value does not translate into any type of value outside of that 'closed bomb' test. Powder performance varies widely by actual application. Relative quickness is one of several preliminary considerations when assessing a powder's suitability for a particular application by ballistics, but nothing more than that.
