Abstract

Submunition will overturn when dispersed by clusters due to many factors. Design and calculation of such submuniton need to study its high angle-of-attack aerodynamic characteristics. Shock-capture and shock-fit grids were adopted to the numerical analysis of submunition. Based on control volume method, the simulation uses the realizable k-ɛ turbulence equations to complete the governing equations. The zero-attack drag characteristics of the submunition as a function of Mach numbers is given as well as aerodynamic characteristics between 0°~180° angle of attack when Mach number is 1.5. The results approximate to Missile Datcom.

Key words： aerodynamic characteristics; submunition; supersonic; high angle-of-attack; CFD
