1. A gas supply system, comprising: a receiver assembly;a gas storage vessel coupled to the receiver assembly;a main poppet positioned at an end of the gas storage vessel and sealing the gas storage vessel when the main poppet is closed;a pilot poppet positioned in the main poppet and sealing the ga
1. A gas supply system, comprising: a receiver assembly;a gas storage vessel coupled to the receiver assembly;a main poppet positioned at an end of the gas storage vessel and sealing the gas storage vessel when the main poppet is closed;a pilot poppet positioned in the main poppet and sealing the gas storage vessel when the pilot poppet is closed; anda chamber positioned behind the main poppet, wherein a first end of the main poppet located at the chamber has a larger diameter than a second end of the main poppet located at the end of the gas storage vessel,wherein when the pilot poppet opens, gas from the gas storage vessel is released into the chamber to exert pressure on the main poppet to open the main poppet, wherein the main poppet moves into the gas storage vessel into a pressure stream of escaping gas from the gas storage vessel to open the main poppet, wherein a time for the main poppet to move into the gas storage vessel to reach a stop is less than or equal to about 20 ms. 2. The gas supply system as recited in claim 1, wherein the pilot poppet moves into a pressure stream of escaping gas from the gas storage vessel to open the pilot poppet. 3. The gas supply system as recited in claim 1, further comprising a receiver mounted plunger positioned behind the main and pilot poppets, wherein the plunger pushes the pilot poppet into a pressure stream of escaping gas from the gas storage vessel to open the pilot poppet. 4. The gas supply system as recited in claim 3, wherein, prior to actuation, the plunger is held in a retracted position by a receiver mounted trigger sear linkage. 5. The gas supply system as recited in claim 4, wherein the trigger sear linkage is actuated by a solenoid. 6. The gas supply system as recited in claim 1, wherein the escaping gas flows through a discharge port to a store ejection mechanism. 7. The gas supply system as recited in claim 1, wherein the gas storage vessel is coupled to the receiver assembly by screwing the gas storage vessel into the receiver assembly. 8. The gas supply system as recited in claim 1, wherein the gas storage vessel is pressurized and seals pressurized gas in the gas storage vessel prior to being coupled to the receiver assembly. 9. The gas supply system as recited in claim 1, wherein the main poppet includes a seal to plug an orifice in the gas storage vessel. 10. The gas supply system as recited in claim 1, wherein the pilot poppet includes a seal to plug an orifice in the main poppet. 11. The gas supply system as recited in claim 1, further comprising a receiver mounted sequencing valve, wherein the sequencing valve opens a vent to atmosphere for one side of the main poppet. 12. A method for supplying gas to a store ejection mechanism, comprising: coupling a pressurized gas storage vessel to a receiver assembly;positioning a main poppet at an end of the gas storage vessel to seal the gas storage vessel when the main poppet is closed, wherein a first end of the main poppet located at a chamber behind the main poppet has a larger diameter than a second end of the main poppet located at the end of the gas storage vessel, wherein the chamber is formed between and by attachment of the gas storage vessel to the receiver assembly;positioning a pilot poppet in the main poppet to seal the gas storage vessel when the pilot poppet is closed;pushing the pilot poppet toward the gas storage vessel into a stream of escaping gas from the gas storage vessel to open the pilot poppet and to fill a chamber positioned behind the main poppet with the escaping gas; andexerting pressure on the main poppet with the escaping gas to push the main poppet into the gas storage vessel to open the main poppet, wherein a time for the main poppet to move into the gas storage vessel to reach a stop is less than or equal to about 20 ms, wherein the chamber is not linked to a source of gas other than the escaping gas from the gas storage vessel. 13. The method as recited in claim 12, wherein the main poppet moves into the gas storage vessel against a pressure stream of escaping gas from the gas storage vessel. 14. The method as recited in claim 12, further comprising a receiver mounted plunger positioned behind the main and pilot poppets to push the pilot poppet toward the gas storage vessel. 15. The method as recited in claim 14, further comprising energizing a solenoid to actuate a trigger sear linkage to release the plunger from a retracted position. 16. The method as recited in claim 12, wherein the main poppet includes a seal to plug an orifice in the gas storage vessel. 17. The method as recited in claim 12, wherein the pilot poppet includes a seal to plug an orifice in the main poppet. 18. The method as recited in claim 12, further comprising opening a vent to atmosphere for one side of the main poppet. 19. A gas supply system for store ejection from a vehicle, comprising: a receiver assembly; anda gas storage vessel removably coupled to the receiver assembly; anda main poppet positioned at an end of the gas storage vessel and sealing the gas storage vessel when the main poppet is closed, wherein a first end of the main poppet located at a chamber behind the main poppet has a larger diameter than a second end of the main poppet located at the end of the gas storage vessel, wherein:the receiver assembly includes a charging port for connecting to a pressurized gas source on-board the vehicle, the port is connected to the gas storage volume in the gas storage vessel via a separate port and check valve, and the gas storage vessel is refilled with pressurized gas via the port wherein the pressurized gas from the gas storage vessel is released into and trapped in a chamber in the receiver assembly to exert pressure on the poppet and push the poppet into the gas storage vessel, wherein the main poppet moves into the gas storage vessel into a pressure stream of escaping gas from the gas storage vessel to open the main poppet, wherein a time for the main poppet to move into the gas storage vessel to reach a stop is less than or equal to about 20 ms, wherein the chamber is not linked to a source of gas other than the pressurized gas from the gas storage vessel. 20. The gas supply system of claim 19, wherein a seal is positioned between the gas storage vessel and the port, and the seal functions as a poppet seat. 21. The gas supply system of claim 19, wherein the pressurized gas source is a compressor. 22. The gas system as recited in claim 1, wherein the chamber traps the gas from the gas storage vessel against the main poppet. 23. The method as recited in claim 12, wherein the chamber traps the escaping gas against the main poppet.
