The Aeros Profi is a Ukrainian high-performance 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.

Design and development

The base model Profi wing is a cable-braced, king post-equipped hang glider-style wing for two-place trikes, while the Profi TL is a "topless" design, lacking the king post and using streamlined lower lift struts instead of wires. The topless design lowers the overall height of the wing and allows storage in lower-roofed hangars. A carbon fibre leading edge insert is optional, while winglets are standard on the TL model.

The wing is made from bolted-together aluminium tubing, with its double surface wing covered in Dacron sailcloth. Its 10 m (32.8 ft) span wing has an area of 14.5 m2 (156 sq ft), a nose angle of 128° and uses an "A" frame weight-shift control bar. An electro-mechanical trim is optional.
