A flexible foldable solar generator having an array of a plurality of blankets carrying solar cells hingeably connected to be folded and unfolded. The solar cells are connected together by branches and the branches are connected by connector lines in inner and outer current conducting tracks system arranged outside the blankets. The branches connect the solar cells with the connecting lines in the outer track to form a U-shaped series connection of the cells and the U-shaped series connected cells are connected in parallel by the connecting lines in the inner track where they can be connected to energy systems of the space vehicle.

A pin puller combines an actuator with an anti-friction release mechanism, according to a bilaterally symmetric geometry. The anti-friction tension release mechanism ensures that only negligible friction forces need to be overcome to operate the tension release mechanism. Thus, the actuator is isolated from the large tension force that bears on the tension release mechanism. The bilateral symmetric aspect of the structure provides for mechanical redundancy, so that, in the event that one half of the pin puller fails, it is sufficient that the other half operate properly for the tension to be successfully released. This pin puller avoids premature release because it is not susceptible to static electricity or electromagnetic radiation. The pin puller also avoids generation of large shock waves due to its slow speed of operation and because of the gradual release interaction of mechanical parts within the anti-friction release mechanism.

A solar array concentrator assembly includes a first solar array panel configured to receive solar energy and a first adjustable concentrator coupled to the first solar array panel. The first adjustable concentrator reflects solar energy toward the first solar array panel. A first drive shaft is coupled to the first adjustable concentrator. The first drive shaft is configured to rotate the first adjustable concentrator relative to the first solar array panel to maximize the solar energy reflected toward the first solar array panel.

A satellite system includes a solar wing moveably connected to a satellite central body. A sensor, also coupled to the satellite central body, detects the movement of the body and generates a rate signal based on that movement. Additionally, an actuator, which controls momentum, is coupled to the satellite central body with maximum torque along the thermal shock axis. Subsequently, a rate-dominated thermal shock suppression controller, which is coupled to the satellite central body, receives the rate signal from the sensor to control the actuator.

A satellite has a platform of elongated shape in a direction parallel to a roll axis of the satellite. A deployable arm is pivotally carried by a longitudinally extending face of the platform. A solar generator is carried at the end of the arm by a first motor for aiming the generator through a range of 360° about a pitch axis orthogonal to the direction of elongation of the platform. A second motor rotates the solar generator through a limited angular range about an axis that is orthogonal to the pitch axis and parallel to the plane of the generator. The arm, when deployed, moves the solar generator away from on a stored position in contact with the platform in a direction of a yaw axis.

A solar cell array assembly that is configured to be stowed in the payload bay of a low earth orbit space vehicle utilizes hinged panels comprising foldable outboard panels and inboard panels. The inboard panels are connected along their respective facing edges to an elongated structural boom one end of which is affixed to a deployment arm. The deployment arm has a shoulder connected to the payload bay, an upper arm, an elbow joint and a fore arm. The fore arm provides two rotational drives having respectively orthogonal axes. The panels are shaped to conform to the shape of the hinged payload bay doors which load the panels in the stowed configuration. The Complete Solar array assembly is a six degree of freedom mechanism that articulates the cell substrates out of a stowed volume (payload bay) to a selected orientation for solar array articulation relative to the sun, optimum power generation, and mission operations.
