【Abstract】 The aerodynamic interference between dispenser and submunitions is one of the im portant problems during the development of dispenser/submunition weapon system. The submunition initial movement parameters (initial velocity of separation,ini tial nominal angle of attack,initial velocity of nominal angle of attack) are i mportant for submunition separation processes from dispenser safety and accurate ly. In this paper, the numerical method is employed to study the aerodynamic int erference among dispenser and submunitions, and to the processes of submunition separation from dispenser. It is introduced that the result of simulations of th e processes of submunition separation from dispenser, includes the different eff ects of initial movement parameters (initial velocity of separation, initial nom inal angle of attack, initial velocity of nominal angle of attack).更多还原
