ABSTRACT:
A method and design are disclosed for the introduction of ammonia gas into he rocket motor gas environment wherein the ammonia gas functions to suppress the flash signature.
The firing and pressurization of a sealed container having suppressant vents results in the rupturing of one or more seals for the container containing clathrate means from which adsorbed liquid or gaseus ammonia is boiled out and discharged and mixed with combustion gases prior to being discharged through the exhaust nozzle of a rocket motor.
The design for the container for containing clathrate means include as part of one embodiment a toroidal shaped container for installing within the rocket motor exhaust nozzle wherein the container functions as the throat of the exhaust nozzle of the rocket motor. Other embodiments feature the clathrate means in a sealed container which additionally houses the ignitor means. The combination ignitor-clathrate means container is provided with a seal which ruptures when the ignitor means is fired, and the container is additionally provided with suppressant vents along the periphery and the end of the combination container through which the suppressant gas ammonia is boiled out of the clathrate means and subsequently discharged and mixed with rocket motor combustion gases prior to being exhausted through a rocket motor exhaust nozzle environment wherein the ammonia gas functions to suppress the flash signature.
