The A-I-R Atos is a German high-wing, single-place, rigid wing hang glider designed by Felix Ruehle and produced by A-I-R GmbH of Halblech.[1]
Design and development
[edit]The Atos was originally designed as a competition rigid wing hang glider in 1998, with production commencing the following year. Since then the design has undergone almost continuous refinement and a succession of model numbers. It remained in production in 2012.[1][2]
The aircraft structure is made from carbon-fiber-reinforced polymer. The wing uses minimal cable bracing and incorporates both flaps and spoilers for roll control. The aspect ratio for most models is in the range of 11:1 or 12:1. Achieved glide ratios run as high as 20:1. Later models incorporate a horizontal tailplane for improved stability.[1][3]
The Atos gliders are designed for folding for ground transportation. The largest model, the Atos VX, for example, can be folded into 5.80 x 0.48 x 0.20m (19.0 x 1.57 x 0.66 feet) in 18 minutes and weighs 47.5 kg (105 lb).[3]
Later model Atos are compatible with the Swedish Aerosport Mosquito power pack.[3]
The wing was also later developed into an ultralight trike, the Ultralight Design Atos Trike. It can also be fitted to the Veleria Dedalo Strike-T trike.[4]
Operational history
[edit]The Atos series have been flown in the rigid wing class in World Hang Gliding Championships since 1999 and have won titles on many occasions.[2]
