37-mm bore ram accelerator of CARDC

摘要

A 37-mm bore ram accelerator has been built at Hypervelocity Aerodynamics Institute (HAI) of CARDC. Subdetonative acceleration mode (i.e. the thermally-choked mode) has been demonstrated, and projectiles are accelerated from 1,100 m/s to 1,450 m/s through a 4.8m-long accelerator, with averaged acceleration ranging from 7,000 to 11,000 g. Description of this 37-mm ram accelerator facility is given in this paper, together with typical resutls of cold/hot shot tests.
