WebSep 19, 2024 · Abstract. The laser-driven flyer plate is an important loading technology in high energy physics, shock wave physics, and explosive initiation application. How to generate a high-velocity and intact flyer plate by using the laser is a matter of concern for laser driving. In this study, the multilayer flyer plates (MFPs) of Al/Al 2 O 3 /Al and ...
Webvelocity of flyer is a function of explosive to metal mass ratio and the Gurney energy of the explosive and a flyer can be launched to a maximum velocity of approx 5 km/s. An impact of a steel plate moving at 5km/s with the stationary steel plate generates a shock pressure of the order of 1.5 Mbar. WebMay 5, 2024 · For example, Loiseau et al. measured the ability of mixtures of aluminum with gelled NM to accelerate a flyer plate. They found, for aluminum particles from 3.5 to 55 \(\upmu \hbox {m}\) in diameter, that the detonation products delivered more energy to the flyer plate than the baseline explosive within 1–3 \(\upmu \hbox {s}\) and concluded ...

Explosion welding (EXW) is one of the joining methods consisting of a solid state welding process in which controlled explosive detonation on the surface of a metal. During the collision, a high velocity jet is produced to remove away the impurities on the metal surfaces. Flyer plate collides with ...
The Gurney equations give a result that assumes the flyer plate remains intact throughout its acceleration. For some configurations, this is true; explosive welding, for example, uses a thin sheet of explosive to evenly accelerate flat plates of metal and collide them, and the plates remain solid throughout.
