A system is provided for directing a flow of gas, including a launching mechanism, a plenum, a layer of meltable material, and an open-ended uptake component. The launching mechanism is adapted to expel rocket exhaust gas. The plenum includes an upper portion having at least one fire resistant breachable plug. The upper portion is adjacent to the launching mechanism. The layer of meltable material is disposed on the upper portion. The heat generated by the gas melts the layer of meltable material. The open-ended uptake component operatively connects to the plenum. The plug moves onto a lower portion of the plenum due to force generated by the gas onto the plug, and the gas flows through the plenum and the uptake component to vent said gas in a controlled manner.

1. A gas management system for discharging exhaust gas from a missile contained within a launcher, said system comprising: a plenum that defines a chamber for receiving the exhaust gas, said plenum comprising: an upper portion defining a ceiling of said chamber comprising a fire resistant substrate
1. A gas management system for discharging exhaust gas from a missile contained within a launcher, said system comprising: a plenum that defines a chamber for receiving the exhaust gas, said plenum comprising: an upper portion defining a ceiling of said chamber comprising a fire resistant substrate with a plurality of fire resistant uni-directionally movable plugs disposed thereon, each plug being directable into said chamber by the exhaust gas thereby leaving a corresponding opening in said upper portion, said upper portion overlaid by a meltable layer to secure said each plug within said corresponding opening, said meltable layer releasing said each plug in response to exposure to the exhaust gas,a lower portion defining a floor of said chamber, whereinsaid chamber separates said upper portion from said lower portion and receives the exhaust gas through said opening; andan uptake component connected to said plenum via said chamber for venting the exhaust gas. 2. The system of claim 1, wherein the plurality of movable plugs comprise a tapered shape. 3. The system of claim 1, wherein the plurality of movable plugs comprise a stepped shape. 4. The system of claim 1, wherein said uptake component comprises: a first open end connected to said plenum; anda second open end. 5. The system of claim 1, further comprising at least one gas blast protection component over said lower portion of said plenum, wherein said at least one gas blast protection component comprises a plate and a plurality of raised bumps extending from said plate. 6. An exhaust gas directing system for a missile launcher that contains a booster motor, said system comprising: a launching mechanism adapted to expel rocket exhaust gas from the motor;a plenum comprising upper and lower portions that define a chamber, said upper portion having at least one fire resistant breachable plug, wherein said upper portion communicates said gas from said launching mechanism through an opening upon release of said plug into said chamber;a layer of meltable material disposed on said upper portion to secure said plug within said opening on said upper portion, wherein heat generated by said gas melts said layer of meltable material, thereby releasing said plug; andan open-ended uptake component operatively connected to said plenum via said chamber,wherein said plug moves onto said lower portion of said plenum due to force generated by said gas onto said plug, andwherein said gas flows through said plenum and said uptake component to vent said gas in a controlled manner. 7. The system of claim 6, wherein said plug is configured to permit movement away from said upper portion towards said lower portion. 8. The system of claim 6, wherein said at least one fire resistant breachable plug comprises a plurality of fire resistant breachable plugs, wherein only plugs positioned directly below a direct expulsion of said rocket exhaust gas emanating from said launching mechanism are released from said upper portion of said plenum towards said lower portion of said plenum. 9. The system of claim 6, further comprising a layer of fire resistant material under said upper layer. 10. The system of claim 6, further comprising at least one gas blast protection component over said lower portion of said plenum. 11. The system of claim 6, wherein said rocket exhaust gas is expelled directly over a plug, and wherein said plugs only move in one direction. 12. A method for directing a flow of rocket exhaust gas from a missile launcher, said method comprising: directing the rocket exhaust gas onto an upper portion of a plenum comprising a plurality of fire resistant breathable plugs disposed thereon within corresponding openings;melting an upper layer of material from said upper portion, wherein said melting is caused by heat generated by the rocket exhaust gas;pushing said plugs positioned directly exposed to a direct expulsion of the rocket exhaust gas towards a lower portion of said plenum, wherein said pushing is caused by force generated by the rocket exhaust gas onto said plugs; anddirecting said gas through said plenum towards an uptake component to vent the rocket exhaust gas in a controlled manner. 13. The method of claim 12, wherein said plugs are configured to only permit movement away from said upper portion towards said lower portion. 14. The method of claim 12, further comprising providing a layer of fire resistant material under said upper layer. 15. The method of claim 14, further comprising aligning said plugs with said layer of fire resistant material. 16. The method of claim 12, further comprising protecting said lower portion of said plenum from said force generated by the rocket exhaust gas. 17. The method of claim 12, wherein said directing of the rocket exhaust gas occurs directly over a plug.
