Device and method for connecting two parts of a craft

摘要

A device for releasably connecting a first part and a second part of a spacecraft. A clamp is operable to releasably connect the first part and the second part of the spacecraft and to store a prestress strain energy releaseable upon separation of the first part and second part of the spacecraft. The clamp includes a first end and a second end. At least one energy storing system is operable to convert at least a portion of the prestress on the clamp to rotational energy upon opening of the clamp and separation of the first part and the second part of the spacecraft. The energy storing system includes a first fitting part that includes a threaded section, a second fitting part that includes a threaded section, and a connecting device that includes a threaded section complementary to and operable to engage the threaded section of the first fitting part and the second fitting part. The connecting device is operable to link the first end and the second end of the clamp. During separation the fitting parts and the connecting device are operable to rotate in relation to one another to release the first fitting part and second fitting part from the connecting device.
