Abstract
An apparatus to improve combustion efficiency of solid fueled ramjets by ucing or slowing down the mixing between the air stream and the combustion zone near the fuel grain. The mixing process is altered by placing a control device parallel to the longitudinal axis of the combustion chamber and spaced from the interior wall of the solid fuel. The device may take the form of a co-axial tube which may be perforated slotted or segmented.
Claims3
In a solid fuel ramjet engine having a combustion chamber defined between a forward injector plate, which contains an air inlet to enable the passage of ram air into the engine and to act further as a flame retarder, and an after nozzle and surrounded by a solid fuel grain, the improvement comprising:
- baffle means fastened within said chamber between said injector plate and a point near the aft end of said grain;
- and
- said baffle extending from said point near the aft end of said fuel grain to a point spaced from said injector plate and comprising interposing baffle surfaces between the inner surface of said grain and longitudinal axis of said chamber,
