Air-Britain Archive 1992-03 / Extracts. Paris 1946 (2)

The prototype SO.7010 Pegase on the left had a large cabin for up to 6 passengers and a retractable tricycle undercarriage. Its 400 hp Mathis G16R engine was an 'X' in-line with 4 rows of 4 cylinders and its design was based on the 8-cyl G8R inverted vee in-line with a new crankcase having another vee 8 mounted upright on top. It appears there was no market for the Pegase as no production is known.
On the right is the SO.1100 Ariel which was basically a helicopter with a pusher propeller added. It was a compact egg with a bright orange paint scheme. The three jet-tipped rotor blades were driven by a Turbomeca compressor powered by its 170 hp 7-cyl Mathis G7R radial engine. This also supplied shaft drive for a wooden 3-blade fixed pitch pusher propeller inside an annular ring, replaced by an orthodox tail boom on the SO.1110 and SO.1120.
