摘要:
A spacecraft (10) comprised of a plurality of functionally organized, fully independent modules (12,14,16,18). Selected ones of the modules are moveable foldably in a "clamshell"-like manner between assembled positions, wherein various components of the spacecraft are generally not readily accessible, to a service position in which virtually all of the components of the spacecraft are substantially readily accessible for service or testing. Logically organized and routed harnesses (46,47,46') comprised of numerous electrical and mechanical elements (24-38) enable the clamshell-like folding movement of selected modules. Conventional electrical and mechanical connectors (48) associated with the harnesses permit quick detachment and complete removal of selected modules from the spacecraft. The fully modular design significantly reduces the time required to gain access to the components on each of the modules and eliminates time consuming and extensive disassembly procedures that would ordinarily be required when performing service or test procedures on the spacecraft. The fully modular configuration also permits parallel manufacturing and testing of the independent modules, thus significantly reducing the design-to-market cycle time for the spacecraft. The modular design also facilitates replacement of selected modules with modified modules to produce derivative spacecraft or to tailor the performance of the spacecraft to better meet the needs of a particular mission.
摘要:
Ein Nutzlastträger für Raumstationen besteht aus einer Gitterstruktur, die mit einer ersten, als Anschlußpunkt an die Raumstation ausgebildeten Außenfläche auf eine an der Raumstation angeordnete, mit Versorgungsanschlüssen versehene und als Nahtstelle ausgebildete Aufnahmeeinheit aufsetzbar ist, wobei diese Außenfläche ein zur Nahtstelle passendes Kopplungselement aufweist. Weitere Außenflächen der Gitterstruktur sind ihrerseits als Aufnahmeeinheiten entweder für weitere Nutzlastträger oder für aktive bzw. passive Nutzlasten ausgebildet.

摘要:
A technique for reducing the cost of manufacturing spacecraft, wherein many resistive heaters (14), and sensors (20) such as thermistors and strain gauges are integrated into a spacecraft equipment module (10 or 12) during fabrication. Prior to testing, selected heaters (14) and sensors (20) are activated through external connectors (18) to the equipment module (10 or 12). Prior to launch of the spacecraft, selected heaters and sensors needed during flight are activated and the heaters and sensors needed for test are deactivated.
摘要:
The invention concerns a device for the suspension of a payload in a space launch comprising annular chambers of fluid with variable geometry (12i) installed between said launch and said payload and first (10') and second (11') rigid members fixed, on either side of said chambers (12i), to said payload and to the launch respectively so as to transmit the stresses between the latter through said chambers. The fluid chambers (12i) and the first (10') and second (11') rigid coupling members are coextensive, ring-shaped and coaxial with a longitudinal axis common to the launch and to the payload. The first (10') and second (11') annular rigid coupling members each comprise external (10a', 10b') and internal (11a', 11b') ribs respectively, axially separated by one of the annular fluid chamber (12i).
摘要:
The drive unit for adjusting satellite components requiring orientation such as thrusters (2) comprises two linear drives (9, 10) on which steering rods (5, 6) are articulated via gimbals. The rods (5, 6), like the additional bracing struts (14), are connected via globe joints (3, 4 or 5) to the components requiring orientation such as the platform (1) of the thrusters (2). An alternative or additional articulation is provided via a globe joint (13) on the main satellite body.
