title = "Study of angle of boattail in bullets with partial core",
abstract = "Under critical conditions of production requirements, as in war and for high volume applications of fire, rejected bullets with partial core can be used, however they could have variations in their boattail angle. It produces expansion waves and trailing shock behind the bullet in supersonic flow and small deviations can originate variations in their flight, which can be measured and compared with the generated Mach numbers. Thus numerical simulations were performed on 7.62 mm bullets with partial core with these variations and they were compared with images obtained by the Schlieren technique. These simulations and experiments showed that 7.62 mm bullets have similar results with angles of 10°, 45° and 90° in the boattail, regardless they have partial or whole core. Then is demonstrated that a partial core bullet does not generate additional variations by changing the angle of the boattail, compared to a whole core bullet.",
