The Airkraft Sunny is a Swiss ultralight aircraft that was originally produced by the Dewald Leichtflugzeugbau Gmbh of Bad Schönborn, Germany, then Tandem Aircraft KG of Saulgau, Germany and more recently by Airkraft Gmbh Leichtflugzeugbau of Beringen, Switzerland. The aircraft is supplied as a kit for amateur construction or as a complete ready-to-fly-aircraft.[1][2][3]
Design and development
The aircraft complies with the Fédération Aéronautique Internationale microlight category rules. It features an unusual diamond-shaped biplane, strut-braced closed wing layout, a two-seats-in-tandem enclosed or open cockpit, fixed tricycle landing gear and a single engine in pusher configuration. The upper wing is swept back, while the lower wing is straight, but mounted further aft. The two wings are joined by swept tip rudders. The elevons are mounted to the lower wing only.[1]
The aircraft is made from bolted-together aluminum tubing, with its flying surfaces covered in Dacron sailcloth. Standard engines available include many models of Hirth, Rotax, BMW and Verner 133M powerplants, ranging from 65 to 80 hp (48 to 60 kW).[1]
