Abstract

The invention discloses an array detection device and an evaluation system for ammunition explosion shock waves. The device comprises a bullet-shaped casing, a detection film, a detection unit, a signal processing unit and a microstrip antenna. The bullet-shaped casing is provided along an axis for transmission Shock wave propagation channel, a plurality of detection cavities are arranged on the side wall of the propagation channel, and the opening diameters of the plurality of detection cavities decrease in turn along the propagation direction of the shock wave. The opening of each detection cavity is covered with a detection film, and the elastic shell There is an accommodation cavity between the outer wall and the propagation channel; the detection unit is used to record the critical pressure value of each detection film when it ruptures, and when the detection film is ruptured, the detection film with the largest diameter is obtained. The critical pressure value is sent to the signal processing unit; the signal processing unit is used to load the critical pressure value to the microstrip antenna for radiation. The invention can realize the dynamic evaluation of the ammunition explosion shock wave in the real battlefield environment.

Description

technical field [0001] The invention relates to the technical field of ammunition power assessment, in particular to an array detection device and an assessment system for ammunition explosion shock waves. Background technique [0002] In actual combat, the assessment of the damage capability of artillery shells mainly involves the spatial distribution of the shell explosion physical field and the damage degree of the target. The real-time online damage assessment provides powerful data support for commanding fighters and decision makers to grasp a credible and reliable combat situation. The explosion shock wave of the shell is one of the main indicators of its damage power assessment. At present, the explosion shock wave evaluation of ammunition is mainly based on static test tests, that is, a shock wave detection device is fixedly installed near the ammunition, and the explosion shock wave is detected by the shock wave detection device. However, the dynamic detection of ...
