Folding Wings Deployment Device

A folding wings deployment device of the present invention is configured to comprise: a wing unit (10) with wings which are deployed in a folded state; and a deployment device (20) for generating deployment force to deploy the wings during a linear movement process which occurs when gas pressure is elevated and for generating damping force by the action of the oil, thereby solving insufficiency of the deployment force by using high-pressure gas and buffering a deployment impact due to rapid deployment of the wings at the same time.
