Abstract:	The development bottleneck exists in the head velocity and extended continuity performance of the conventional liner, and the depth of penetration cannot meet the requirements. In order to improve the penetration performance of the jet, this paper designs a new type of cylinder horn liner, and carries out experimental and simulation studies on its jet formation and penetration process, compares the effects of the shape of the liner on the head and tail velocity, jet morphology and penetration performance, and investigates the penetration performance under different radii of curvature. The results show that in the same cylindrical part the jet formed by the new liner is better than the cylinder cone and cylinder spherical segment liners in terms of continuity, and its head velocity is increased by about 12.26% and 35.38% compared with the cylinder cone and cylinder spherical segment liners, respectively, and the depth of the penetration is increased by about 21.43% and 39.06%, and the head velocity of the jet is increased with the increase of the radius of curvature of the flared part, the jet morphology is more slender, and the aperture diameter increases. The research results can provide a basis for the structural design and performance analysis of the new liner.
