The GyroTec DF02 is a German autogyro, designed and produced by GyroTec Michael Obermaier of Wörth am Rhein. The DF02 is supplied as complete ready-to-fly-aircraft.[1]

Design and development

[edit]

The DF02 features a single main rotor, a single-seat enclosed cockpit with an optional bubble canopy, tricycle landing gear and a twin cylinder, liquid-cooled, two-stroke, dual-ignition, fuel-injected 70 hp (52 kW) Hirth 3503 engine in pusher configuration.[1]

The aircraft uses a 7.45 m (24.4 ft) diameter, high-inertia Averso Aviation rotor, with a chord of 21.6 cm (8.5 in). The rotor head was designed by GyroTec and includes a disc-style rotor brake, pre-rotator and integral articulation stops. The DF02 has an empty weight of 175 kg (386 lb) and a gross weight of 300 kg (661 lb), giving a useful load of 125 kg (276 lb).[1]

The bubble canopy can be removed for flight in warm weather. In 2009 the canopy size was increased to accommodate taller pilots.[1]

One thought on “Cannabaceae”

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
