    Abstract: A solid rocket motor uses at least one thermally conductive wire or at least one pair of electrically conductive wires to increase a burn surface area of a propellant grain and thus a thrust of the rocket motor. The rocket motor includes a pulse chamber containing a burnable propellant grain, a propellant inhibited center bore bonded to surfaces of the burnable propellant grain, and at least one conductive wire coupled to the burnable propellant grain and arranged in variable regions along the propellant inhibited center bore. The conductive wire is configured for passive or active activation to ignite the propellant inhibited center bore that subsequently burns in the variable regions. The thermally conductive wire is formed of a refractory metal or refractory alloy material that enables the entire length of the wire to be heated simultaneously or nearly simultaneously when the wire is passively activated.

    Abstract: The invention relates to a space cold gas thruster operating with a solid propellant. The cold gas thruster of the invention comprises a tank (1) suitable for containing a solid propellant and a tank (1) heating device suitable for sublimating said solid propellant and forming gaseous propellant, the tank (1) having an aperture (7) for transferring said gaseous propellant outside said tank (1), such as a nozzle (7). The invention also relates to a process for determining the amount of remaining propellant in the propellant tank (1) of a cold gas thruster of the invention.

    Abstract: A detonation thrust-producing device (10) includes an explosive (32) located in a recess (34) in an external surface of a body (16). Detonation of the explosive expels material out of the recess, providing thrust to the body in an opposite direction. A mass, such as a metal disk (58), may be placed blocking or covering the external opening. The body may be a part of a vehicle, such as an airborne projectile (12). The thrust-producing device may include multiple detonation motors arrayed around the body, capable of being individually or multiply detonated. Such thrust-producing devices may be used for attitude adjustment, steering, or other control of the flight of the projectile or other air vehicle. The detonation thrust-producing devices have the advantage of a faster-response time than propellant-based devices, and do not need the nozzles that are used with many propellant-based devices.

    Abstract: The present invention describes a hybrid rocket motor that includes a first solid reactant and at least one thrust nozzle and at least one moveable combustion control member within the hybrid rocket motor that restricts the contact of a first fluid reactant to the solid reactant in the combustion chamber. In this way it is then possible to regulate the exposure of the solid reactant to the fluid reactant and thus control thrust.

    Abstract: The rocket motor nozzle assembly of this invention includes a throat insert (22) and a carbon or silica protective eyelid (50). The throat insert has a carbon throat support (30) and a refractory metal shell (42, 44, 46). The shell is positioned radially inside the throat support to cover the inner surface of the throat support. The protective eyelid (50) covers a sufficient portion of the forward surface region (42) of the shell and the underlying converging portion of the throat support to protect these components against particle impingement. The protective eyelid extends sufficiently far forward along the converging/diverging pathway to cover and protect the forward face or edge of the throat insert and prevent the combustion gases from passing under the throat insert and reaching the radially outer surface of the throat insert. However, the protective eyelid leaves the throat surface region of the shell exposed to the converging/diverging pathway.
