The Orel VH2 Streamline is a French ultralight aircraft that was designed by Jean-Francois Boudet and is under development by Orel Aircraft of Selles-Saint-Denis, introduced at the AERO Friedrichshafen show in 2015. The aircraft will be supplied complete and ready-to-fly.[1]
Design and development[edit]
The VH2 Streamline was designed to comply with the Fédération Aéronautique Internationale microlight rules. It features a cantilever low-wing, low-mounted tailplane, an enclosed cockpit with two-seats-in-side-by-side configuration under a bubble canopy, fixed tricycle landing gear and a single engine in tractor configuration.[1]
The aircraft is made from carbon fibre. Its 9.0 m (29.5 ft) span elliptical wing has an area of 9.6 m2 (103 sq ft) and mounts flaps. It has an electrically-operated canopy and a side-stick controller. The cockpit width is 110 cm (43 in). The standard engine used is the 100 hp (75 kW) ULPower UL260i four-stroke powerplant.[1]
As of 2015 the company was looking for a partner to bring the aircraft to production.[1]
