Abstract: Thrusting apparatus for guiding missiles or other projectiles. A plurality of side-by-side solid propellant gas generators are provided to discharge axially into a plate which has a rim and a plurality of nozzles which extend radially in the plate and discharge radially from the rim so as to produce thrust normal to the projectile axis on a single plane. The nozzle structure is of laminant construction whereby the materials may be varied from materials which are resistant to high temperature gas flow and erosion in the area of the nozzles and gas flow passageways to medium temperature resistance materials which require good structural properties at other locations for high quality at minimum cost. The configuration also allows minimum volume and length.
