Dijkstra, M.H. Carton, E.P. Contributor Walker, S. (editor) Bless, J. (editor) Publication year 2008 Abstract Jacketed penetrators of mid calibre type have been produced by explosive cladding of various jackets on two different kinds of tungsten heavy alloy (WHA) rods. The jackets, of different thicknesses, were made of steel-37, stainless steel 316L, titanium grade (2, 3) and pure titanium grade 2. The jacket increased the flexural rigidity of the core rod with a factor 2 - 9.5. Sabots and propellants to fire these penetrators were produced as well. These jacketed and monolithic WHA penetrators were fired with penetrator velocities of about 1300 m/s on a layered target consisting of steel/rubber/steel of 3 mm thickness each and steel hardness HB 480. The penetrator condition was recorded with flash radiography. Thin jackets, increasing the flexural rigidity of core penetrator with a factor two, were not sufficiently stiff to perforate the layered target intact. Thicker jackets improved the jacketed penetrator condition, which means a less fragmented penetrator.
