    • An exhaust nozzle bell for a rocket engine including a first part arranged on a motor of the rocket engine, and a second part coupled to the first part. The second part having a stowed position in which the second part surrounds the first part and is positioned closer to the motor, and an operating position in which the first part and the second part form a continuous shape and the second part is arranged farther from the motor. Moreover, the nozzle can include an extension mechanism structured and arranged to extend the second part from the stowed position to the operating position, the extension mechanism including a plurality of swiveling extension arms, wherein the extension arms have first and second ends. Furthermore, each of the extension arms comprise one of a sliding and rolling element on an end facing the second part of the exhaust nozzle bell. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
    • 一种用于火箭发动机的排气喷嘴钟,包括布置在火箭发动机的马达上的第一部分,以及耦合到第一部分的第二部分。 第二部分具有收纳位置,其中第二部分围绕第一部分并且位于更接近电动机的位置;以及操作位置,其中第一部分和第二部分形成连续形状,并且第二部分布置成更远离 发动机。 此外,喷嘴可以包括延伸机构,其构造和布置成将第二部分从收起位置延伸到操作位置,延伸机构包括多个旋转延伸臂,其中延伸臂具有第一和第二端。 此外,每个延伸臂在面向排气喷嘴钟的第二部分的端部上包括滑动和滚动元件中的一个。 本摘要既不旨在限定本说明书中公开的发明,也不旨在以任何方式限制本发明的范围。

    • An antenna reflector for satellites or space vehicles having a number of hexagonal individual reflectors (1) which can be arranged around a rigid central element (2). The reflectors (1) are connected to the central element (2) by a support structure (3) that can collapse to hold the reflectors in a compact storage state or be extended to deploy the reflectors. The reflectors (1) are folded like an umbrella in a transport state when the reflectors are collapsed and at the place of use, they are brought into their operating positions and spread out, so that they collectively form a reflector surface. Each reflector (1) has a foldable surface structure connected by a multiple number of ribs (11) to a rigid, central structure (12).
    • 一种用于卫星或航天器的天线反射器,其具有多个可以布置在刚性中心元件(2)周围的六边形单个反射器(1)。 反射器(1)通过支撑结构(3)连接到中心元件(2),支撑结构(3)可以折叠以将反射器保持在紧凑的存储状态,或者延伸以部署反射器。 反射器(1)在反射器被折叠时在运输状态下像伞一样折叠,并且在使用的地方,它们进入其操作位置并展开,从而它们共同形成反射器表面。 每个反射器(1)具有通过多个肋(11)连接到刚性中心结构(12)的可折叠表面结构。

    • A method for the production of a reflector for antennas to be used in outer space in which a thread (7) is wound on a winding spindle (1), to obtain a netting or network structure. The winding spindle (1) has contour segments (2) on its surface, whose contour corresponds to the contour of a sector of the reflector surface being produced. After winding, the resulting thread network structure is hardened on the winding spindle (1) and the thread network structure is divided into individual sections. The contour segments (2) are separated from the winding spindle (1) and together with the sections of the hardened network structure thereon are fitted together on an assembly rig so that the individual sections collectively form a reflector. The winding of the thread of the network structure on the spindle can vary in at least one direction or in its angle of placement a, so that the network structure has a different, selectable rigidity in individual areas.
    • 一种用于生产用于外圈的天线的反射器的方法,其中线(7)缠绕在卷绕轴(1)上,以获得网状或网状结构。 卷绕轴(1)在其表面上具有轮廓段(2),其轮廓对应于正在产生的反射器表面的扇形轮廓。 绕组后,所得螺纹网络结构在卷绕轴(1)上硬化,螺纹网状结构分为单独部分。 轮廓段(2)与卷绕轴(1)分离,并且与其上的硬化网络结构的部分一起装配在组装钻机上,使得各个部分共同形成反射器。 网络结构在主轴上的线圈的缠绕可以在至少一个方向或其放置角度α上变化,使得网络结构在各个区域中具有不同的可选刚性。
