Abstract (en)

[origin: EP0884553A1] The assembly comprises a chamber (122) containing a pressure source (120), connected to the launch tube (100) through a cylinder (130) with perforations (132) which are exposed in sequence as the projectile is ejected from the tube. The cylinder is located between the chamber containing the pressure source and the launch tube expansion chamber (140). The spacing, size and number of the perforations in the cylinder are designed so as to ensure a constant pressure in the launch tube behind the projectile.
