The applicability of turns-counting distance measurement technique was analyzed in the case of different ballistic.A ballistic engineering calculation method was proposed based on the number of revolutions and lead.The change of the projectile lead during flight was analyzed based on the principle of aerodynamics.The main factors that lead to lead change and the trends of lead were discussed.The results show that turns-counting distance measurement technique applies to the low elongation ballistic and the rising phase of curved trajectory
and the transonic zone should be avoided in the trajectory design.The engineering algorithm is verified by experiments.The algorithm can be used to calculate the number of revolutions required by turns-counting distance measurement
which can provide a reference for the design calculations and engineering development of the turns-counting distance measurement technique.
