The Aurore MB 02-2 Mini Bulle (English: Mini Bubble) is a French ultralight aircraft, designed by Michel Barry and produced by Aurore Sarl of Sauvagnon. The aircraft is supplied as a kit or as plans for amateur construction.[1][2]

Design and development

The Mini Bulle was designed to comply with the Fédération Aéronautique Internationale microlight rules and is an evolution of the Aurore MB 02 Souricette with a more modern look as opposed to the MB 02's antique 1920s appearance. The Mini Bulle features a strut-braced shoulder-wing, a single-seat enclosed cockpit under a bubble canopy, fixed conventional landing gear and a single engine in tractor configuration.[1][2]

The aircraft is made from wood with its flying surfaces covered in doped aircraft fabric. Its 9 m (29.5 ft) span wing employs single supporting struts. The standard recommended engine is the 18 hp (13 kW) Hirth F23 two-stroke powerplant or the JPX 505. Differences with the earlier MB 02 include longer main landing gear legs to allow more propeller clearance and an aerodynamic cowling.[1][2]

In 2015 the aircraft kit was 6,000 and plans sold for €230.[1][2]
