Abstract
A series of free-flight tests were conducted at Mach 2 to verify a sabot design that was used to launch a tandem projectile configuration, of similar profile and size, from a 110 mm smooth bore. The projectiles consisted of a four-fin cone-cylinder model with a length-to-diameter ratio l/d of 6. Four shots were fired, two at an open range to test the sabot functioning and model-sabot integrity at launch, and two in the dREV aeroballistic range to obtain detailed trajectories of the projectiles to study aerodynamic interference effects. The sabot separation process, the measured trajectories, including the separation aspects of the trailing projectile relative to the leading one, are analyzed and discussed. The stability of models and their aerodynamic characteristic are compared relative to each other and with the results of a same configuration fired individually. Detailed flow photographs showing the complex shock wave structure and their interference on both models flying in close proximity are also given.
