The Aeros Still is a Ukrainian single-surface ultralight trike wing, designed and produced by Aeros of Kyiv. The wing is widely used on Aeros trikes as well as by other ultralight aircraft manufacturers.[1]
Design and development
[edit]The Still wing is a cable-braced, king post-equipped hang glider-style wing designed as a docile beginner and flight training wing for two-place trikes. It comes in one size, the Still-17, named for its metric wing area of 17.4 m2 (187 sq ft).[1][2]
The wing is made from bolted-together aluminium tubing, with its single surface wing covered in Dacron sailcloth. The wing's crosstube is exposed and is of a floating design. Its 10.3 m (33.8 ft) span wing has a nose angle of 122°, an aspect ratio of 6.1:1 and uses an "A" frame weight-shift control bar.[1][3]
