Title: Rocket motor with large surface area explosive - having set of large radial ribs alternating with small radial ribs
Inventor: DALET FRANCIS
IPC: F02K9/36
Filed: 1975-01-31
Abstract: A rocket propulsion arrangement has a cylindrical casing with a radial set of propulsive material elements attached to it, and protruding inwards like a set of ribs, with a space (2) down the middle acting as the combustion chamber. The outer casing (1) has a layer of inhibiting varnish (4) about 50mm thick, and inside this, a sleeve (3) made of perforated stainless steel, the ratio of holes to solid sheet being between 10 and 45%, and forming a resilient support for the explosive ribs.
