A Cylindrical Nose Tip Projectile(CNTP) was studied,which is an ogive nose projectile with a cylinder pin on the nose. By combining numerical simulation with experiment, the penetration mechanism and penetration effect of CNTPs with different nose parameters,penetrating into 9 MPa and 28.4 MPa concrete targets with different velocities were studied. The results primarily show that CNTPs penetrate concrete without terradynamic cavity. Due to the penetration of the cylindrical nose tip,target strength is degradated. The penetration of CNTPs with specific nose parameters is better than that of the ogive nose projectile.
