A deployment or hinge mechanism and, more particularly, a compact unmanned aerial vehicle (UAV) wing deployment mechanism is provided. The deployment mechanism includes a hinged mechanism that stows in a stacked configuration and deploys in a level configuration.

Deployment mechanism

An airship system, including an inflatable airship of predetermined volume adapted to be filled with gas and to rise to a predetermined altitude, said airship having a hull formed from an inflated flexible gas containment primary envelope, at least one lifting envelope located within the primary envelope for containing the lifting gas, where the lifting envelope will expand to substantially occupy the space of the primary envelope when the airship is at its predetermined high altitude, at least one secondary envelope located within the primary envelope, which can be inflated when said lifting envelope is at lower altitudes to fill the balance of the space of the primary envelope, and air handling means external to the primary envelope and communicating with the secondary envelope for filling and emptying the secondary envelope.

External pressurization system for lighter than air vehicles

The subject invention relates to an apparatus and process for testing various parameters and properties of high strength flexible, fabric laminates. In particular, the apparatus comprises a machine using individually controlled loads to test various material parameters.
