摘要:
A spacecraft includes payload equipment and bus equipment, each of the payload equipment and the bus equipment being coupled with a secondary structure arrangement. The spacecraft is configured to structurally interface with a launch vehicle upper stage only by way of an exoskeletal launch support structure (ELSS) that provides a first load path between a launch vehicle upper stage and the secondary structure arrangement. The spacecraft is configured to deploy from the launch vehicle upper stage by separating from the ELSS. In some implementations, the first load path is the only load path between the spacecraft and the launch vehicle upper stage, and substantially all of the ELSS remains with the launch vehicle upper stage. Because the secondary structure may be substantially less massy then the ELSS, subsequent orbit raising maneuvers may then be executed with a spacecraft having a reduced dry mass.

The invention relates to an artificial satellite which includes: a mounting structure supporting equipment-bearing walls; a launcher-adapter rigidly connected to the mounting structure; a first radiator (26); and at least one first system (42) for transporting heat by a fluid, including at least one duct (44) having a first heat-exchange section (50) and a second heat-exchange section (52), said second heat-exchange section (52) being capable of being in thermal contact with said first radiator (26), characterised in that said first heat-exchange section (50) is in thermal contact with at least one portion of the launcher-adapter (16). The invention also relates to a method for filling a tank of propellent gas of said artificial satellite.

Device for the hold-down and controlled release of space satellites installed on launchers and loads installed on space satellites, comprising a blocking member (5) made up of segments (4) radially displaceable from a mutually approached retaining position to a mutually spaced-apart release position of a connecting screw (6). In order to control the radial displacement of the segments (4) between the retaining position and the release position there are provided a rotatable element (16) coaxial with the blocking member (5), an articulated mechanism (3) which operatively connects the rotatable element(16) with the segments (4) of the blocking member (5), and linear motors (23, 24) for driving the controlled rotation of the rotatable element (16) and, through the articulated mechanism (3), the simultaneous displacement of the segments (4) of the blocking member (5).
摘要:
Systems, methods, and apparatus for dual port ring compatible satellites are disclosed. In one or more embodiments, a method for removably attaching at least one spacecraft (220) to a payload attach ring (310) on a launch vehicle (140) involves attaching a strongback (215) of each of the spacecrafts to two respective payload ports (320) of the payload attach ring on the launch vehicle. In one or more embodiments, the strongback of each of the spacecrafts is attached to each of the two respective payload ports via a respective beam mounted to a respective port adaptor plate. The method further involves separating the strongback of each of the spacecrafts from the two respective payload ports of the payload attach ring on the launch vehicle by using at least one mechanical actuator on each of the beams.

The invention relates to a device for temporary connection with a longitudinal axis (X) and for pyrotechnic separation, including a pyrotechnic expansion tube (14) mounted in a space (11) arranged in a connection area between a first (2) and a second (4) assembly to be separated, the second assembly (4) consisting of a stack of layers (12.1, 12.2) adhered to one another, the two assemblies (2, 4) being connected together by two metal parts (10.1, 10.2), said metal parts being attached to the first assembly and adhered to the outer layers (12.1) of the second assembly (4), wherein the adhesion surface between said outer layer (12.1) and the adjacent inner layer (12.2) is smaller than the adhesion surface between two inner layers (12.2) forming a fusible layer, such that, when the pyrotechnic expansion tube (14) is used, the outer layer (12.1) separates from the adjacent inner layer.
