Abstract : The interaction of liquid propellant drops with the beam from a modest power carbon dioxide laser has been used to observe evidence of strong internal circulation and corresponding instability of these drops. The drops appear to relax, but characteristic times may extend to as much as 0.1 sec. The drops are found to break up under relatively small perturbations when highly circulating. The implications in gun environments where interdrop collisions may occur shortly after drop formation, as well as the potential importance to possible research configurations, are discussed.
