摘要:
A launch vehicle payload that includes at least two spacecraft (210(1), 210(2)) is disclosed. The launch vehicle includes a single payload adapter (225). Each spacecraft has a launch vehicle adapter structure (215(1), 215(2)) providing a respectively coplanar structural interface directly with the single launch vehicle payload adapter. The spacecraft share a launch vehicle payload fairing (221) volume substantially side-by-side and are detachably coupled together such that a positive clearance is provided between adjacent, non-abutting structural body surfaces of each spacecraft.
摘要:
The invention relates to a propulsion bay (1) intended to be transported, at least temporarily, in a space launch vehicle (2) and comprising an adapter (3) that co-operates with at least one system located, at least temporarily, on board the bay (1), said system comprising an electrical power supply. The bay is characterised in that it also comprises at least one electric space propulsion engine that can be powered by the power supply of the system.
摘要:
A coupling/uncoupling mechanism (10A) according to the present invention maintains, when a male coupling body (30A) is coupled to a female coupling body (20A), a condition that the male coupling body (30A) is inserted in an insertion space (SO) and the other end of a lever member (22) is in a position in proximity to the insertion space (SO), so that an engaging surface (23a) of an engaging member (23) is contacted with an engageable surface (31a) of the male coupling body (30A). When the male coupling body (30A) and the female coupling body (20A) is uncoupled, the other end of the lever member (22) moves to a direction to be apart from the insertion space (SO), so that the engaging surface (23a) moves toward a withdrawing direction (D2). This allows releasing the contacting of the engaging surface (23a) with the engageable surface (31a). This provides that sufficient fastening force can be achieved with a simple configuration and the coupling status can be retained with a smaller force as compared with such a fastening force, and further, a recombination can be easily achieved even after a separation is made.

A shock attenuating mounting bracket (30) for isolating a hardware component from shocks associated with an underlying structure includes a base (32) and a planar strip (34) coupled together. The base (32) is coupled to the underlying structure and the planar strip (34) is coupled to the hardware component. The planar strip has at least two bends (36,38) along its length for dissipating the shocks associated with the underlying structure. The planar strip can be C-shaped with first and second free ends coupled to the base and a mid-section coupled to the hardware component. Alternatively, the planar strip can have a C-shaped notch formed within and the bracket can include a multi-sided gusset plate that braces the base to the planar strip. The bracket is designed to improve the shock attenuation in shock sensitive designs while maintaining sufficient structural stiffness to sustain random vibration loads and minimum natural frequencies greater than 100 Hz.
摘要:
Satellites are launched to a first orbit (A) on a launch rocket. The satellites are connected together, forming a satellite cluster (22), that is propelled from the first orbit to a higher mission orbit (B) by thrustors on each satellite. The satellite cluster is formed so that satellite cluster rotation from aerodynamic drag on the individual satellites is minimized. The thrustors are sequenced to control satellite cluster attitude during the transition to the second altitude. At the second altitude, the satellites are separated from the satellite cluster and propelled to their mission orbits using their own thrustors and attitude system.
摘要:
A spacecraft avionics module that is for the most part functionally independent of a core spacecraft structure, and provides its own structural integrity, thermal management and some level of power management. The illustrative embodiment of the module is formed as a flat panel that also serves as a thermal radiator. Electronic components are mounted directly onto the panel, which is normally attached by mounting hardware to the core spacecraft structure, through a backbone interface that provides data interconnection between modules and, in some cases, supplies unregulated power to the module. The module may include a power regulation function, or may also include power storage and power generation functions. For complete independence, the module may also include its own attitude control system.

An apparatus for reducing terminal-to-terminal circuit resistance and enhancing heat transfer in a rotary power transfer apparatus of the roll ring type comprising a connecting thimble (11) for attaching an external power cable (23) to a cone shaped terminal (14) which is attached to a tab (18) integral with outer ring (19). An inner ring (25) having a spherical recess mates with the spherical end (30) of a tie connector (26). A cone shaped terminal (14) is fitted to a second connecting thimble (11) for attaching a second external power cable (23).
