METHOD FOR GENERATING AN AIR SHOCK WAVE OF A GIVEN DURATION Russian patent published in 2023 - IPC G01N3/313 F42D1/02 

FIELD: generating air shock waves.

SUBSTANCE: invention can be used to generate air shock waves of a given duration when testing, for example, air protective devices. Charges for forming an air shock wave are placed sequentially on the same axis in the direction of wave formation at an equal distance between themselves and connected with a detonation cord. The length I_c of which is determined from the ratio I_c \u003d u_c×τ₊, where u_c is the speed of propagation of the detonation wave along the detonating cord, τ₊ is the duration of the front of the air shock wave. The number of charges N, providing the required duration τ_d of explosive impact is determined by the formula N=τ_d /τ +-1. The weight of each of the subsequent charges C_s is changed from the weight of the previous charge C_s by the value δC, determined from the ratioδ C=(C_s -C)/(N-1).

EFFECT: formation of a shock wave with a given duration and expanded scope.
