The Gyroflug SC01 Speed Canard is a two-seat German duck plane made of glass fiber reinforced plastic .

history

In 1976, the pilots Peter Krauss and Jörg Elzenbeck built the first VariEze in Germany according to original construction plans by Burt Rutan in 3000 working hours under the auspices of the Oskar Ursinus Association . In 1978 they founded the company Gyroflug Ingenieur GmbH Stuttgart for the structural revision and series production . After J. Drumm carried out flow studies in the wind tunnel of the TH Darmstadt , Richard Eppler designed three new profiles for the wing and canard. After evaluating the results, an aircraft with a glider fore fuselage with seats in tandem was created.

The accidental death of Peter Krauss on July 17, 1979 delayed the development, but Jörg Elzenbeck, with the help of his team, the u. a. Rudolf Voit-Nitschmann was part of the project. The first prototype (D-EEEX) took off for the first flight on December 2, 1980 in Baden-Baden, the second (D-EEEW) on April 17, 1983. The type certification by the Luftfahrt-Bundesamt followed on September 30, 1983, then began serial production. The Speed Canard was the first type-approved aircraft in Germany in duck design.

At the end of 1984 Justus Dornier took over Gyroflug and developed the aircraft further. In 1986 the SC-01B appeared with winglets that were extended by 25 cm, which could also be retrofitted to the machines produced so far. A more powerful Lycoming O-320 with 118 kW power and a three-blade propeller could now be ordered as an option . 26 aircraft were ordered with this engine and nine more were converted to this engine. In April 1988 Gyroflug moved to Hohentengen and called itself from 1990 Gesellschaft für Flugzeug- und Fiberverbund-Technologie mbH .

The design and the sidestick control, which was new at the time, were probably "too far" ahead of their time. Disadvantages such as the limited payload and the small overhead locker with only 15 kg payload ensured that the Speed Canard could not attract a large number of customers despite its very good flight performance. Despite spectacular flights such as the transatlantic flight of an SC-01 B-160 (D-EJDC) to Oshkosh and back, the machine, which cost around DM 300,000 with standard instrumentation, only sold slowly from 1990 onwards. After building 58 aircraft, nine of which were delivered to the USA, the former Gyroflug filed for bankruptcy on December 9, 1992.

In December 2010, 35 flew in Europe alone.

The aircraft is a duck plane with an elevator on the fuselage bow, the front part of which forms the bow section of the two-seater glider Grob G 103 Twin Astir. It is powered by a four- cylinder Lycoming O-235 -M1 boxer engine with 85 kW or a Lycoming O-320-D1A with 118 kW via a pusher propeller in the rear of the fuselage. In order to increase the performance, two KHD T117 jet engines from Klöckner-Humboldt-Deutz were planned as a drive option , which should enable a top speed of 420 km / h.

At the ends of the wing there are winglets in which the rudders are integrated. It is controlled by a mechanical sidestick on the right side of the cockpit. The two rear landing gear legs are rigid and have an aerodynamic wheel fairing, while the nose wheel is retractable. To make it easier to get in and out, it can also be retracted on the ground. The Speed Canard then rests on a small rubber buffer that is attached to the outside of the nose gear.

The original design equipped with the Lycoming O-235 had lower drag, lower weight, greater range and a higher payload. Consumption increased from 18 l / h to over 28 l / h due to the more powerful engine, the higher curb weight, IFR equipment and the longer winglets.

Compared to Rutan's own construction VariEze, the maximum load factor was lower, but the Speed Canard exceeds the VariEze by up to 30% due to the high aerodynamic quality and the new canard and wing profile in terms of range and cruising speed.
