Abstract
A self-contained missile canister includes a cylindrical shell having a plenum or manifold at the breech end for receiving and deflecting missile exhaust gases. A plurality of tubular exhaust ducts or uptake tubes route exhaust gases from the plenum to locations near the missile exit end of the canister. Protrusions on the missile, such as guide rails or aerodynamic control fins, extend from the missile body at locations lying between the exhaust ducts. The tubular exhaust ducts resist the exhaust pressure in hoop tension, so are lightweight. Ablative material may line the exhaust ducts. The exhaust ducts may be supported by longitudinally disposed support beams, preferably I-beams. In one embodiment, each I-beam supports two exhaust ducts.
