The Haufe Buzzer 2 is an American high-wing, strut-braced single-seat motor glider that was designed and constructed by Walter Haufe.[1][2]
Design and development
After Haufe's earlier Buzzer was deemed less than successful, due to the insufficiently reliable Nelson Aircraft engine, Haufe retired that design and designed a new aircraft, which became the Buzzer 2. Intended to be a cross between a conventional sailplane and a light aircraft the aircraft was built with a Шаблон:Convert wing span and has a 16:1 glide ratio.[1][2]
The Buzzer 2 is constructed with a welded steel tube fuselage and a wooden wing, all covered with doped aircraft fabric covering. The relatively low 8:1 aspect ratio wing uses a single spar and is supported by a single lift strut. The wing employs a modified NACA 2412 airfoil. The landing gear is a fixed monowheel and two wing-mounted outrigger wheels that support the wing during taxiing. The engine is a Curtiss snowmobile engine that turns at a maximum rpm of 6000, powering the propeller through an oil-immersed 2:1 chain reduction drive, giving a propeller speed of 3000 rpm.[1][2][3]
Only one Buzzer 2 was constructed.[1][2][4]
Operational history
Haufe reported that the aircraft uses Шаблон:Convert to take-off and climbs at about 500 feet per minute (2.5 m/s). The aircraft was still on the US Federal Aviation Administration registry in July 2011, registered in the Experimental - Amateur-built category.[2][4]
