Determination of the Gurney velocity for the unconventional aluminum‐water explosive**

Abstract The present work is dedicated to the determination of the Gurney velocity of the unconventional aluminum‐water explosive. The paper presents the experimental arrangement, the diagnostic equipment used, and the main results that have been obtained. The experiments report the accurate velocity measurement of projectiles accelerated by aluminum and copper underwater exploding wires. Based on the results obtained, a Gurney velocity of 1.88 km/s has been obtained for the unconventional aluminum‐water explosive. The result is discussed and compared with typical values for standard explosives.
