Flight Dynamics and Dispersion Characteristics of S-Curve and Roll-Through-Zero Bomblets.

Abstract

Two new ballistic-type self-dispersing bomblets which utilize passive control of the radial orientation of the trimmed lift force are described and the motion of these bomblets as determined by simplified theory and by exact six-degree-of-freedom simulation is discussed. Some of the unique aerodynamic characteristics of these bomblets as determined from wind tunnel tests are also described. Impact pattern predictions, using the Monte Carlo method, show that properly designed S-Curve and roll-through-zero bomblets can achieve large uniform patterns for low-altitude high-speed delivery conditions; however, configurational asymmetries, if not suitably restricted, can significantly modify the bomblet performance.
