Study on reference materials for high burning rate propellant

Based on the mature formulation of high burning rate propellant,the candidates of reference materials,rational size and preparation process of the sample were determined.Three kinds of high burning rate reference materials with burning rate constant range of 35~60 mm/s,70~90 mm/s and 100~120 mm/s were prepared.After uniformity and stability of the samples passed test examination,characteristic values and uncertainty of the reference materials were defined by multiple constant tests.The results show that the reference materials for high burning rate propellant can meet the calibration requirement of strand-burners with various range of burning rate and ensure accuracy and reliability of test results.
