Aerodynamic Dispersion Techniques
Abstract
The motion and dispersion characteristics of four proposed types of aerodynamic self-dispersing bomblets (S-curve bomblet, roll-through-zero bomblet, dual-mode bomblet, and spinning-disk bomblet) are evaluated for representative tactical cluster-dispenser delivery environments. Six-degrees-of-freedom simulations are used to investigate the flight dynamics of each type bomblet, and in addition, approximate motion theories are developed for the S-curve and roll-through-zero bomblets. The effects of various configurational asymmetries on the motion and dispersion are considered. Impact patterns are computed for each of the proposed bomblets, and the area coverage capabilities are compared for low-speed and high-speed dispenser opening conditions, ranging in altitude from 300 to 2000 feet and flight path angle from 5 to 45 degrees. The area coverage of the proposed bomblets is contrasted with that of the CBU-24 munition and a hypothetical radial-force-ejection system. The aerodynamic characteristics of each type bomblet are reviewed, and the problems of selecting candidate configuration are discussed.
