March 24 - Aeroscraft Corporation (Aeros) has been granted a patent by the United States Patent and Trademark Office (USPTO) for the outer structure of its Aeroscraft cargo airship.

The utility patent covers the multifunctional Aeroshell, which defines the outer shape of the airship and serves structural and operational functions as an internal truss system, explained Aeros.

The patented Aeroshell provides the major external frame of the vehicle and includes three main structural features: a rigid internal main frame, the vehicle's skin, and a rigid Aeroshell frame interposed between the main frame and the skin.

Aeros says that the Aeroshell is light but counteracts the loads imposed by cargo payloads, aerodynamic lift and pressure, static lift, and shear loading or movement.
