Summary

In order to decrease the drag the parametric wind-tunnel researches of the influence of the head part length and its from on the drag coefficient of cylinders with the body nose needles were conducted. The detalization of the flow structure of one or two needle bodies by the method of “large particles” (FLIC) was done.
