The invention of Dr. Karl Wölfert; an 800 cubic meter capacity non-rigid dirigible, driven by an internal combustion Daimler gasoline motor of 8 hp. Wölfert made ascensions on “Deutschland” at Tempelhof-Berlin on August 28 and 29, 1896 and on March 6, 1897, but did not have a lot of success navigating his machine. On June 12, 1897, an exhibition of “Deutschland” in front of government dignitaries and military men ended disastrously. Carrying Dr. Wölfert and his mechanic Robert Knabe, the airship rose to 200 meters and was suddenly engulfed in flame, dashing both men to their death. The airship was the first to have an accident involving the combustion of the hydrogen lift gas resulting in fatalities.
In 1880, Karl Wölfert and Ernst Georg August Baumgarten attempted to fly a powered airship in free flight, but crashed.
In 1888, Wölfert flew a Daimler-built petrol engine powered airship “Deutschland” at Seelburg.
Single seat single engined flex wing aircraft with weight shift control. Rogallo wing. Pilot suspended below wing in trike unit, using bar to control pitch and yaw/roll by altering relative positions of trike unit and wing. Undercarriage has three wheels in tricycle formation. Push right go left nosewheel steering independent from yaw control. Aluminium tube trike unit, with optional pod. Engine mounted below wing driving pusher propeller.
The WAT the title stands for Wolfe Aviation Trike. In concept it is simple enough a monopole trike using a 2 inch (5cm) square section aluminium pole, adjustable in height to suit various Rogallo wings. Wolfe offers a variety of engines, with or without reduction drive, various seat options and also a selection of undercarriage designs. One of these undercarriages is unique as far as trikes are concerned in that it has retract¬able main wheels which fold behind the power pack to reduce drag. The WAT is also available with a double nosewheel. Another drag reducing option is a fabric pod.
To make the WAT as versatile as possible, the hang point uses a clamping arrangement, the idea being that the glider can be attached without drilling holes through the keel tube.
Standard engine is the Cuyuna 215 cc unit with reduction drive but among the engine options is a Cuyuna ULII-02. Price of the trike unit with 215 cc engine and reduction drive was $1690.
