Abstract
The exploding wire technique has been used to create flyer impact loading on the inner boundary of hollow cylinder [1,2]. This paper examines the dynamic performance for expanding cylindrical flyers driven by two types of line source conditions: (1) an exploding wire (EW), and (2) a high explosive (HE) PBX 9404‐3. Calculations are performed to establish the velocity and kinetic energy imparted to flyers of varying mass in terms of energy and mass of the source. The differences in performance observed between the EW and HE sources are attributed to differences in their equation‐of‐state adiabatic expansion behavior. The calculated velocities are close to the data variation observed in the EW experiments. The results presented allow one to specify the energy conditions required to perfom cylindrical impact experiments at different scales.
