Zusammenfassung:	A structure of a front end cover made of FRP is consisted of a tower-shaped protrusion and a square frame, in which the center portion of the tower-shaped protrusion is a pyramidal cone, and the two sides on the inside and outside thereof are separately formed with interleaved pre-cracked channels. The square frame is circumferentially formed with a tower-shaped protrusion and has a plurality of positioning corner ribs formed on the corners. Furthermore, the peripheries of the positioning corner ribs are formed with frame pre-cracked channels so that the front end cover can be split into completely and uniformly cracked blocks along the pre-cracked channels and uniformly disperse outwardly during a firing operation of the projectile.
