Solid rocket grain configurations
WebThe conventional single grain of solid propellant is typically formed large enough to at least substantially fill a chamber in the lateral thrust motor, resulting in a substantially thick grain. However, when creating the chemistry for such high burn-rate propellant material, it is more difficult to keep the burn rate consistent from part to part. WebThe reusable solid rocket motor, or RSRM, is assembled and tested by ATK Thiokol Propulsion near Promontory, Utah. Each motor consists of four steel tubes, or segments, lined with 1.1 million pounds of solid fuel propellant. …
