Air Est Goeland Goeland Role - Motor glider National origin - France Manufacturer - Air Est Services Designer - Robert Clavé First flight - October 1987 Status - Production completed Number built - 2 (1998) Developed from - Scheibe Spatz The Air Est Goeland (English: Gull), sometimes called the Clavé Goéland, after the designer, is a French parasol-wing, T-tailed, single-seat motor glider that was designed by Robert Clavé and produced by Air Est Services of Marly, Moselle in kit form for amateur construction. Design and development The aim of the Goeland was to provide a viable motor glider design based on wings taken from a Scheibe Spatz glider. The kit was supplied with two fuselage halves and the tail parts only, leaving it up to the builder to secure the Spatz wings and engine to finish the aircraft. The finished aircraft is of mixed construction with a fibreglass fuselage and wood and doped aircraft fabric wings. The 13.20 m (43.3 ft) span wings are mounted on a short pylon above the fuselage, although other sailplane wings can be employed in place of the Spatz wings. The specified König SC 430 18 kW (24 hp) radial engine is mounted in pusher configuration behind the wing and above the tail boom, although other similar engines can be used. The aircraft features tricycle landing gear and a cockpit bubble canopy. In 1998 the basic kit was US$4400 and included just the fuselage halves and tail. A finished fuselage was US$8400 and plans were advertised at US$200. Building time was estimated at 300 hours.

Design and development The Pelican has an unconventional layout, based on the Fauvel AV.36, with a low aspect ratio wing, twin rudders mounted at mid-span and a pusher configuration Solo 210 engine mounted in the rear fuselage producing 9 kW (12 hp). The aircraft is constructed from fibreglass, with some surfaces fabric covered. The 7.2 m (23.6 ft) span wing is semi-tapered, tapering outside the rudders and employs a Fauvel F4 17% airfoil. The fuselage is just 2.00 m (6.6 ft) in length, making the aircraft very compact. The landing gear is monowheel gear, with a small tail wheel and outrigger wheels at midspan. With the Solo engine the take-off distance is 180 m (591 ft) and the landing distance 67 m (220 ft). Cruise speed is 93 km/h (58 mph). A variety of engines can be fitted. In 1998 a completed aircraft was US$12,950 and a kit was US$8,000. The kit did not include the engine, propeller or instruments. Construction time from the supplied kit was estimated at 300 hours. One example was reportedly completed and flying in 1998.
