A nonaerodynamic sabot stripper has been designed and implemented for use with a 40.00‐mm smooth bore research gas gun. The stripper consists of several metal parts to stop and contain the sabot while allowing the carried object to pass unhindered through it. The single‐piece sabot is stopped by impacting replaceable layers of 19‐mm‐thick aluminum and steel plates and 3.2‐mm‐thick rubber sheets. The metal plates and rubber sheets have 25.4‐ and 31.8‐mm diam holes, respectively, for passage of the carried object. The sabot stripper is located 230 mm from the muzzle of the gas gun and is aligned before each shot using a special metal fixture that is inserted into the gun muzzle. Cubes measuring 12.7 mm have been launched in a flat‐faced orientation. Targets consisting of 76.2 mm×76.2 mm plates of various thicknesses are positioned in an assembly that attaches to the sabot stripper and is located 57 mm behind it. The velocity range for the experiments was from 0.61 to 0.94 km/s.
