ow and drag coefficient cased by different shapes of warheads is analyzed, Р combined with the wind tunnel experiment data. The results show that in the outer flows of the Р missiles with circular-arc warheads, due to the high pressure region in front of the missile and the Р low pressure region exists near the warhead, the drag coefficient varies in some special way, and Р with the same inflow speed, the drag coefficient may decrease when the warhead bluntness Р increases. As the mach number increases, the drag coefficient of the missiles with the same shape Р will decrease and then increase. The results of the research have reference significance in the Р design of circular-arc shaped missile warhead. Р Key words: Circular-arc; missile; aerodynamic characteristics; drag coefficient Р Р 7
