Design and development
The Souris Bulle was designed to comply with the Fédération Aéronautique Internationale microlight rules. The aircraft features a strut-braced high-wing, a two-seats-in-tandem enclosed cockpit under a bubble canopy, fixed conventional landing gear and a single engine in tractor configuration. The rear seat has very limited visibility.[1][2]
The aircraft is made from wood with its flying surfaces covered in doped aircraft fabric. Its 11.25 m (36.9 ft) span wing employs single supporting struts. The standard recommended engine is the 60 hp (45 kW) JPX 4T two-stroke powerplant or a 45 hp (34 kW) Volkswagen air-cooled engine. The Souris Bulle has a glide ratio of 18:1.[1][2][3]
The standard day, sea level, no wind, take off with a 45 hp (34 kW) engine is 52 m (171 ft) and the landing roll is 91 m (299 ft).[3]
In 2015 the aircraft kit was €13,300 and plans sold for €380.[2] The manufacturer estimates the construction time from the supplied kit as 650 hours.[3]
