The Gazuit-Valladeau GV-103 Gazelle was a French-built light two- to four-seat training, aerobatic and touring aircraft of the late 1960s.

Design and development

[edit]

The first GV-103L, as it was originally called, was a two- or three-seat light touring aircraft first flown in 1969. Later referred to as the GV-103 and powered by an 86 kW (115 hp) Lycoming O-235 flat-four engine, it led to several production variants with two, three and four seats using engines of increasing power within the same airframe. It had a side-by-side seating layout and a fixed tricycle undercarriage with a longer nosewheel which gave the aircraft a pronounced tail-down attitude on the ground. Its construction was primarily metal but included some glass fibre structures and plastic bonding, novel at the time.[1][2]

First flown on 1 May 1969, the GV-103 first appeared in public at the Paris Air Show in June 1969. The first two-seat production prototype GV-1020 Gazelle was on display at the Paris 1971 Show. It was intended to meet a club market for basic and aerobatic training.[1][2]

The second Gazelle to fly was the prototype of the four-seat GV-1031 tourer, powered by a 112 kW (150 hp) Lycoming O-320 flat-four engine.[1] An intermediate, three-seat variant with a Rolls-Royce built 97 kW (130 hp) Continental O-240 engine was planned[1] but may not have been built. A four-five seat variant with a 134 kW (180 hhp) engine and retractable undercarriage was also planned, and feasibility studies of a twin-engine version made, but neither reached the construction stage.[2]

Operational history

[edit]

By November 1972 seven Gazelle prototypes were flying and the GV-1301 received its French certification in April that year, with the CV-1020 expected to follow in January 1973. The GV-1020 had only a short operational career and was no longer on the French civil aircraft register by January 1983,[3] though two GV-1031s, one dismantled, remained registered in mid-2010.[4] In 1970 plans for the Canadian company Mondair Aviation to build the Gazelle range under licence as the Mondair 115/130/150 were announced.[1] One GV-1031, without engine, reached Canada,[5] but no North American production followed.
