The present invention is a variable geometry lighter-than-air (LTA) aircraft that is adapted to morph its shape from a symmetric cross-section buoyant craft to an asymmetric lifting body and even to a symmetric zero lift configuration. The basic structure is a semi rigid airship with movable longerons. Movement of the longerons adjusts the camber of the upper and/or lower surfaces to achieve varying shapes of the lifting-body. This transformation changes both the lift and drag characteristics of the craft to alter the flight characteristics. The transfor...
1. An aircraft comprising: a flexible envelope that encloses a base structure, a pair of upper longeron rods and a pair of lower longeron rods with each longeron rod pivotally connected to the base structure, and a pair of envelope expansion arms;each upper longeron rod in the pair of upper longeron rods further including a curved shape extending between a fore end and an aft end with a vertex at the local maximum of the curved shape, wherein the curved shape extends away from a lateral axis of the aircraft to support the flexible envelope;each upper lon...
