The SSW, or Sezione Sperimentale Volo Vela, was formed by the Aeroclub Volovelistio Milanese to maintain and repair the club’s gliders and also to build new designs. Eng Edgardo Ciani designed the Uribel single-seater Standard class sailplane, and after five examples of the Uribel and Uribel B had been built a small series of the improved Uribel C was started, this version having a completely redesigned wing and a fuselage of reduced cross section, but otherwise being similar to the B.

Like its contemporary, the Standard Austria, the Uribel C is a cantilever shoulder wing monoplane of all-wooden construction with a ‘butterfly’ V-tail. The C’s plywood-covered wings are of Eppler 257 aerofoil section and of 17% thickness/chord ratio; air brakes are fitted and there are no flaps. The fuselage is a wooden monocoque structure, with the cockpit canopy faired completely into the top profile of the nose section. There is a fixed monowheel and a small tailskid.

The SSW, or Sezione Sperimentale Volo Vela, was formed by the Aeroclub Volovelistio Milanese to maintain and repair the club’s gliders and also to build new designs.
