Space module assembly apparatus with docking alignment flexibility and restraint

摘要

A berthing mechanism especially for use in berthing and compliant air-tight securing between manned space vehicles and modules. The interface is provided by a pair of annular rings, one of which is typically, mechanically attached to the vehicle and the other to the module to which it is to be docked and secured. One of the two rings is attached to a base by a resilient bellows. The facing surface of one annular ring is joined to a base by a cable laced through alternating pulleys attached circumferentially so that the interface surface of that ring may be tilted to accommodate angular misalignment as said annular rings are brought into docking (berthing) contact. Interleaving guide flanges with chamfered sides provide at least some rotational misalignment correction. A plurality of electro-mechanical actuator/attenuator units provide means for extending one annular ring toward the other in the final stages of docking, for absorbing initial docking shock and for drawing the annular rings into tight interface contact. Locking hooks provide for securing the interfaces.
