Abstract

The present study aims to address, by experimental meaning for a previous defined and published particular configuration, the issue of optimum RDX/Al-foil mass ratio in blast enhancement applications. Using thin aluminum foils as case envelope, the explosive charge was wrapped up prior detonation in open field by employing 20, 60, 110 and 200 grams of aluminum. The experimental data in terms of overpressure, impulse and fireball dimension and duration are discussed. The measurements clearly indicate for the explosive-aluminum foil case a blast enhancement compared with the bare explosive case. Aluminum wrap up methodology influence in terms of overpressure and impulse for the 20 grams aluminum case was also looked into.
