Abstract: Air as conventionally known is comprised of about 78% nitrogen and 21% oxygen with other trace gases such as carbon dioxide, neon, and hydrogen. Other gases (e.g. helium) and partial vacuums have both a lower density and a higher speed-of-sound from that of conventional air or even some highly utilized propellant gases. The present application and described embodiments take advantage of these principles to provide a purge gas mixture and system to increase the speed of a projectile exiting the muzzle-end of a gun barrel. A partial vacuum may also be used in certain applications.

Abstract: Rocket armament launchable from a tubular launcher with an outside launcher non-ignition securing and motor separation during flight and a method to prevent the ignition of the armaments rocket even in the event of actuation of the armaments pyrotechnic assembly, which normally serves to eject the armament from the launcher and to ignite its rocket motor, wherein the armament comprises a gas dispersion assembly, which when the armament is not encased in the tubular launcher, prevents the ignition of the rocket motor even if the armaments pyrotechnic assembly is actuated; and a cutting and separation assembly that is actuated by the pressure of the rocket motor gases for mechanically cutting a structural connection between the rocket motor and the armaments effective payload and separate them during their flight.

Abstract: This disclosure describes various techniques and systems for rapid low-cost access to suborbital and orbital space and accommodation of acceleration of sensitive payloads to space.

Abstract: A cold-gas munitions launch system is disclosed. In the illustrative embodiment, the system includes a munitions canister, a gas generator, and a sled. The sled supports a munition. The gas generator is located in the aft end of the munitions canister. When ignited, the gas generator produces gas, which drives the sled forward. As the sled reaches the end of the canister, the munition is launched by its own inertia, at a velocity that is within the range of about 3 to 9 g. After the munition clears the canister and travels at least about 150 feet from it, the munition's booster is ignited.

Abstract: The illustrative embodiment of the present invention is a munitions launch system. The launch system comprises a canister and a cold launch system. In the illustrative embodiment, the cold launch system comprises a sled and a release system. In the illustrative embodiment, the release system includes a sled release mechanism, which releasably secures the sled to the munitions canister, and a munitions release mechanism, which releasably secures a munition to the sled. Actuation of the sled release mechanism releases the sled for movement within the canister. After the sled moves some minimal distance under applied force, the munitions release mechanism “automatically” actuates, releasing the munition from the sled so that the munition can be ejected from the canister.

Abstract: A launch assist system for supplementing the launch acceleration forces of a projectile, rocket or missile. An airtight chamber covered by a flexible elastic membrane supports a platform in the center of the membrane; the platform is electromagnetically coupled to a cocking mechanism that withdraws the platform into the chamber. Air within the chamber is removed and compressed to be stored in a holding tank as the platform is lowered into the chamber and as the flexible elastic membrane extends into the chamber. The electromagnetic coupling may be triggered to release the platform to permit the stored energy in the extended flexible elastic membrane, and in supplemental force members, to apply acceleration forces to a launch vehicle; the compressed air stored in the tank is simultaneously released to fill the chamber as the flexible elastic membrane is withdrawn.

Abstract: A gas generating eject motor includes a case containing an ignitable low temperature gas generant material that does not produce toxic gases upon the combustion thereof. The gas generant material is generally contained with a screen enclosure housed within the case. An igniter is disposed within the gas generant material for selectively igniting the gas generant to thereby generate combustion gases. A nozzle is disposed within an open aft end of the case for focusing and directing the combustion gases generated by the ignited gas generant material. The case is constructed and arranged to be separably attached to the aft end of a rocket to be launched from a launch platform, so that, upon ignition of the gas generant, the combustion gases focused by the nozzle will apply a thrust to the rocket and thereby propel, or eject, the rocket from the launch platform, at which time the combustible propellant of the rocket motor will ignite and the eject motor will be separated from the rocket.
