Aircraft with passive folding wings that deploy from a compact configuration using an external activation device, eliminating the need for onboard propulsion or control systems. The wings are hinged to a folding bearing that provides the folding functionality, and are aligned with their axes along the longitudinal axis in the packed state. An external carrier supplies energy to operate the activation device, which moves the wings into flight mode.
