Flyer plate motion and its deformation during flight

Velocity and peripheral deformation of a flyer plate, driven by the detonation of contact explosive, have been studied during its flight both theoretically and experimentally. In theoretical formulations, density or velocity of the detonation products behind the flyer plate have been assumed to vary linearly; the results thus obtained compare well with the experimental results. Several experiments were performed in which the guard ring size and air gap between the explosive and the plate were varied. The arrangement which gave negligible peripheral deformation is presented.
