Low Cost Rocket Motor Case and Method of Fabrication.
Abstract
The rocket motor case includes a cylindrical body section which is formed of commercially available seamless steel tubing, with the aft end being swagged and threaded to provide a means of containing the nozzle block (molded graphite or similar material). The forward end of the motor case is fabricated with an inside upset which is threaded to accept a head end closure. The head end closure is threaded to facilitate attachment of payload section. The propellant is cast through the nozzle end (with the head closure already attached) then the nozzle block, along with the aft-end igniter, is inserted and held in place by the aft end closure. The aft end swagging will facilitate the attachment of stabilizing fins to the rocket. (Author)
