Device for deploying and retracting a flexible structure, flexible deployable structure and satellite provided with such a device

摘要

The device has a tape spring (10) including an axis of unfurling and refurling parallel to a device first axis and a rotor rotated about a second axis perpendicular to the former axis. The tape spring is autonomously passed from a state in which the spring is wound around the rotor to an unwound state. The spring is mounted bent in two in a shape of U with two branches (11, 12), and includes two ends (17) of the two branches fixed rigidly to respective anchor points (6), where one of the ends of respective branch of the spring is mounted between two jaws of the respective anchor point. The tape spring is made of a corrugated sheet. An independent claim is also included for a flexible unfurlable structure.
