Profi A Profi TL wing mounted on an Aeros-2 trike General information Type Ultralight trike wing National origin Ukraine Manufacturer Aeros Status In production (2013)

The **Aeros Profi** is a [Ukrainian](/source/Ukraine) high-performance [ultralight trike](/source/Ultralight_trike) [wing](/source/Wing), designed and produced by [Aeros](/source/Aeros) of [Kyiv](/source/Kyiv). The wing is widely used on Aeros trikes as well as by other [ultralight aircraft](/source/Ultralight_aircraft) manufacturers.[1]

## Design and development

The base model Profi wing is a [cable-braced](/source/Flying_wires), [king post](/source/King_post)-equipped [hang glider](/source/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](/source/Lift_strut) instead of wires. The topless design lowers the overall height of the wing and allows storage in lower-roofed hangars. A [carbon fibre](/source/Carbon_fibre) [leading edge](/source/Leading_edge) insert is optional, while [winglets](/source/Winglets) are standard on the TL model.[1][2]

The wing is made from bolted-together [aluminium](/source/Aluminium) tubing, with its double surface wing covered in [Dacron](/source/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.[1][3][4]
