| Abstract: |
| The work aims to study the effect of long-term storage aging on the range of certain projectile and determine the range of effective extended range firing angle. The range of a certain projectile used in 130 mm naval gun under different storage aging time was analyzed by numerical simulation and the variation law of range and the range of effective extended range firing angle with storage time were revealed. Combined with the functional relationship between range and storage aging time and firing angle of the projectile, a range variation model characterized by residual thrust ratio was proposed. The range of the projectile firstly increased and then decreased with the increase of the firing angle under the same storage aging time. At the same firing angle, the range decreased linearly with the storage aging time, and the range of the effective extended range firing angle decreased gradually. The cubic polynomial was used to fit the functional relationship between the effective extended range ratio and the firing angle, of which the correlation coefficient exceeded 0.997 0. The correlation coefficient between the fitting result of the range variation model and the range simulation calculation result of the projectile was greater than 0.998 5, which indicated that the range variation law could be accurately described by the proposed range aging model. Storage aging will significantly affect the range and the range of effective extended range firing angle of the projectile, which can not be ignored in the actual storage and use process. |
