This paper deals with the aerodynamic design of unguided higher caliber clustered sub-munitions dispensed from a missile descending a.t near vertical attitude in its terminal phase so as to impact at the desired pattern. A body dominated configuration with split I laps at the rear end has been considered for the subniunition. The submunition, after dispensing from the main missile attains equilibrium angle of attack as the centre of pressure coiiicides with centre of gravity. Extensive wind tunnel tests have been conducted on the configuration with split flaps to evaluate the aerodynamic characteristics. Trajectory simulation studies carried out using these aerodynamic data shows that the dispersion pattern of unguided submuni-tions can be tailored to maximise the damage over an area on ground targets. © 1996 by the American Institute of Aeronautics and Astronautics, Inc.All rights reserved.
