Abstract:
Acceleration of projectiles in ballistic devices by means of high-rate extrusion of polyethylene through a conical nozzle is experimentally and theoretically studied. Quasi-one-dimensional gas-dynamic model of a polydisperse mixture of gas and powder particles and a viscoplastic model of a deformed piston are used. The results of numerical simulation of the process under study and the results of a series of shots from a powder ballistic device are given. The influence of the geometry of a conical transition and input velocity of the deformed body on the output velocity of a projectile is experimentally investigated.
