    • A propulsion system for use with a satellite comprises a substrate, a communication network and a cluster of individually selectable solid fuel motors mounted on the substrate and operatively connected to the communication network. A controller is also operatively connected to the communication network and operative to select any one of more motors of the cluster of individually selectable solid fuel motors and transmit signals to fire the one or more motors of the individually selectable solid fuel motors. The substrate may have various configurations. The cluster of motors may comprise 10-1000 motors, which may be arranged in a rectangular array or other formation. Subsets of motors having different impulse capabilities may be employed. In this manner, lighter, smaller, flexible and more efficient propulsions systems may be provided for use in attitude control, etc. of satellites.
    • 与卫星一起使用的推进系统包括基板,通信网络和安装在基板上并且可操作地连接到通信网络的单独选择的固体燃料电动机的集群。 控制器还可操作地连接到通信网络,并且可操作以选择可单独选择的固体燃料电动机的集群的多个电动机中的任何一个,并发射信号以对单独选择的固体燃料电动机的一个或多个电动机进行点火。 衬底可以具有各种构造。 电动机组可以包括10-1000个电动机,其可以排列成矩形阵列或其他形式。 可以采用具有不同脉冲能力的电动机的组。 以这种方式,可以提供更轻,更小,更灵活和更有效的推进系统用于卫星的姿态控制等。

    • Embodiments of materials suitable for use as a replacement for Tetrazene and methods of preparing such materials are described. In one embodiment, the material comprises MTX-1, as well as simple salts or complexes derived therefrom. The methods of preparing such materials include combining Tetrazene and an acid to form a suspension, where the acid is nitric acid, sulfuric acid, perchloric acid, or hydrochloric acid. A nitrite salt may be added to the suspension, where the nitrite salt is sodium nitrite, lithium nitrite, potassium nitrite, an aqueous solution of sodium nitrite, an aqueous solution of lithium nitrite, or an aqueous solution of potassium nitrite. In some embodiments, the suspension is stirred until the suspension has a white appearance.
