Methods and apparatus are provided for a single heavy-lift launch to place a complete, operational space station on-orbit. A payload including the space station takes the place of a Shuttle Orbiter using the launch vehicle of the Shuttle Orbiter. The payload includes a forward shroud, a core module, a propulsion module, and a transition module between the core module and the propulsion module. The essential subsystems are pre-integrated and verified on Earth. The core module provides means for attaching international modules with minimum impact to the overall design. The space station includes six control moment gyros for selectably operating in either LVLH (local-vertical local-horizontal) or SI (solar inertial) flight modes.

Heavy-lift vehicle-launched space station method and apparatus

A docking mechanism for the docking of a space vehicle 11 to a space station 12 comprising a flexible tunnel frame structure which is deployable from the space station. The tunnel structure comprises a plurality of series connected frame sections 21, one end section of which is attached to the space station and the other end attached to a docking module 15 of a configuration adapted for docking in the payload bay of the space vehicle 11. The docking module is provided with trunnions 41, 42 adapted for latching engagement with latches 17 installed in the vehicle payload bay and with hatch means 44 connectable to a hatch of the crew cabin of the space vehicle. Each frame section 21 comprises a pair of spaced ring members 31a, 31b interconnected by actuator-attenuator devices 33 which are individually controllable by an automatic control means to impart relative movement of one ring member to the other in six degrees of freedom of motion. The control means includes computer logic responsive to sensor signals of range and attitude information, capture latch condition, structural loads, and actuator stroke for generating commands to the on-board flight control system and the individual actuator-attenuators to deploy the tunnel to effect a coupling with the space vehicle or to adjust the relative attitude of the space vehicle and space station after coupling. A tubular fluid-impervious liner, preferably fabric 51, is disposed through the frame sections 21 of a size sufficient to accommodate the passage of personnel and cargo.

Smart tunnel - docking mechanism

A system for docking a space vehicle 11 to a space station 12 where a connecting tunnel for in-flight transfer of personnel is required. Cooperable coupling mechanisms 51, 52 include docking rings 56, 61 on the space vehicle 11 and space station 12, respectively. The space station is provided with a tunnel structure 15, a retraction mechanism 30, and a docking ring 56 attached thereto. The vehicle coupling mechanism 52 is designed to capture the station coupling mechanism 51, arrest relative spacecraft motions while limiting loads to acceptable levels, and then realign the spacecraft for final docking and tunnel interconnection. The docking ring 61 of the space vehicle coupling mechanism is supported by linear attenuator actuator devices 63 each of which is controlled by a control system (FIG. 10) which receives loading information signals and attenuator stroke information signals from each device 63 and supplies output signals for controlling its linear actuation to attenuate impact loading or to realign the spacecraft for final docking and tunnel interconnection. Retraction mechanism 30 is used to draw the spacecraft together after initial contact and coupling. Tunnel trunnions 21, 22, 23, 25 cooperative with latches 67 on the space vehicle 11 constitute the primary structural tie between the spacecraft in final docked configuration.

Docking mechanism for spacecraft

A triangular space station deployable in orbit. The framework is comprised of three trusses, formed of a pair of generally planar faces comprised of foldable struts which expand and lock into rigid structural engagement forming a repetition of equilateral triangles and non-folding diagonal struts interconnecting the two faces. The struts are joined together by node fittings. The framework can be packaged into a size and configuration which can be transported by a space shuttle orbiter in a single orbital flight and when deployed, provides large work/construction area and ample planar surface area for solar panels and thermal radiators. A plurality of modules are secured to the framework and then joined by tunnels to comprise an interconnected modular array disposed along the free edges of the framework. Thruster units for space station orientation and altitude maintenance are provided. The triangular space station provides a structurally stable unit having sufficiently high structural integrity and natural frequency for facilitating docking, satellite servicing and launch operations.
