Abstract: The present invention is a canister-launched pyrotechnically actuated folding wing UAV. The invention features a method for reliable and irreversible locking of a foldable wing, while enabling compact storage, cost reduction, ease of deployment and aerodynamic performance unattainable in current folding-wing designs. In a specific embodiment, the UAV is pre-packaged in a deployment canister for single-button deployment. The UAV can be offered in a rental system in which part or the entirety of the device can be returned for refurbishing. Additionally, the device can be provided as a fully expendable unit.
