Yes, as far as the particle size-
Very finely powdered manganese dioxide, ceramics glaze material. Pyrotechnic flake Aluminum, of a type used for flash powder. Sold as "American dark",
don't recall the manufacturers number or a mesh/micron size at the moment.
No additional ingredients beyond a stoichiometric MgO2/Al mix in the fuel grain. Ignition required either commercial "thermolite" fuse or other high
temperature methods. Mere black match or visco fuse did not work. Rockets were made on standard black powder core burning engine tools. Roughly
similar Isp, similar operating pressure as far as we could tell. Lower performance than a similarly sized black powder motor due to the heavier fuel
grain and exhaust gas. |
