The Kalbermatten Woopy is a Swiss high-wing, single-place, hang glider that was designed by Laurent de Kalbermatten of Villars-sur-Glâne. The aircraft seems to have been just developed to prototype stage and it is not clear if production was undertaken.^[1]

Design and development

The Woopy fuselage is made from aluminum tubing, with a conventional tail, a seated pilot position and weight shift controls. The wing is inflatable and based on the same concept as an air mattress, kept inflated by two small battery-powered fans. Launch and landing is carried out on foot.^[1]

Much of the development was undertaken using scale flying models to speed construction and reduce pilot risk.^[1]

Two models were developed, the Woopy Fly and the Woopy Jump, plus a powered version of the Woopy Fly.^[1]

Variants

Woopy Fly

Initial model. Its {{convert|9.7|m|ft|1|abbr=on}} span wing is inflatable and has an aspect ratio of 4.58:1 and a wing area is {{convert|20.5|m2|sqft|abbr=on}}. The glider empty weight is {{convert|17|kg|lb|0|abbr=on}} and it has a glide ratio of 9:1.^[1]

Powered Woopy Fly

A powered version of the Woopy Fly was developed in Siberia and flown with a {{convert|150|cc|cuin|1|abbr=on}} two-stroke engine that gave it an empty weight of {{convert|33|kg|lb|0|abbr=on}} and a cruise speed of {{convert|45|km/h|mph|0|abbr=on}} with a {{convert|70|cm|in|0|abbr=on}} propeller.^[1]

Woopy Jump

More portable development model. Its wing is also inflatable and the glider empty weight is {{convert|7|kg|lb|0|abbr=on}} and the aircraft can be folded into a bag {{convert|160|cm|in|0|abbr=on}} long.^[1]
