Шаблон:Short description

The 21st Century Airships SPAS 13 is a Canadian semi-rigid helium airship demonstrator designed and built by 21st Century Airships of Newmarket, Ontario.

Design and development

The SPAS 13 was a development of the earlier SPAS 1 and was designed to demonstrate the advantages of a spherical airship.[1] The 43 ft (13.11 m) diameter spherical envelope is made of Spectra fabric with an inner helium containing envelope of Mylar film reinforced with Kevlar.[1] The two-seat cockpit is internal to the envelope with panoramic windows in the envelope to provide an external view.[1]

The SPAS 13 is powered by two Шаблон:Convert Rotax 503 piston engines on external struts, four vanes behind each engine are used to provide control by deflecting the thrust.[1]
