Abstract

Abstract

It is necessary to take into consideration the effects of elevated-altitude conditions on the propagation characteristics of blast waves when evaluating the explosion power of ammunitions under plateau environment. In order to study the propagation characteristics of blast wave under plateau environment with low pressure, experiments were carried out at simulated plateau environment at altitudes of 500, 2 500 and 4 500 m, respectively. Results show that when the ambient air pressure decreases by 20%, the overpressure, specific impulse and arrival time of blast wave decrease in average by about 9%, 10% and 6%, respectively. Calculated results corrected by Sachs' factor are compared with the test data. It is found that the method proposed in the present study can better predict the blast wave parameters under different environmental conditions. The effects of ambient temperature were also studied. It is concluded that the increase of the initial ambient temperature will reduce the arrival time of blast wave, however, the effects of ambient temperature on the overpressure and specific impulse are not significant. The results have reference significance for the evaluation of warhead explosion power at elevated altitude.
