Abstract
A method and lightweight apparatus (100) that provide linear actuation effected by the controlled inflation of a deployable tube (120) permits the deploying end (125) of the tube (120) to be guided out in a linear motion by a yoke (140) that constrains the inflated portion of the tube (120) immediately behind it A means for imparting resistance to deployment facilitates a smooth actuation by controlling both the rate and the directionality of deployment, and by maintaining a uniform internal pressure in the tube being deployed. A frame assembly (180) at the deploying end (125) of the tube (120) can be configured to interface with a variety of components to be linearly deployed.
