The Centrair 201 Marianne is a training glider seating two in tandem, designed and built in France in the 1980s. It was intended to replace the numerous but ageing gliders equipping French gliding clubs; when Centrair ceased trading in 1988 some eighty Mariannes had been sold, fewer than hoped.
French government support for gliding was generous immediately after World War II but was fading by the 1980s. The Fédération Français de Vol à Voile (FFVV), who administered the French gliding movement, had to become self-financing and were central players in an effort to retain a viable gliding manufacturing base in France. By that time there was a need for a new two seat training glider to replace the existing club fleet of some 270 Wassmer Bijaves, so a competition was launched and won by Centrair. The Marianne design gained financial support from the Ministry of Transport and design support from Dassault Aviation and the Office Nationale d'Etude de Recherche Aerospatiale (ONERA). [1]
The Marianne has a shoulder wing mounted with 3° of dihedral. It has a single spar formed from glassfibre rovings, around which the laminar flow wing profile and ailerons are made from polyvinyl chloride (PVC) foam and glass-reinforced plastic (GRP) sandwich. There are no flaps; double plate aluminium airbrakes extend only above the upper wing surface. [2]
The fuselage is a monocoque pod and boom structure also built with composite sandwich layers, but with carbon fibre added. Its T-tail is constructed from GRP; the tailplane carries an elevator. There is no provision for water ballast. The two tandem seats have a common upper line but two single piece canopies, the forward one forward hinged and the rear opening to starboard. The undercarriage is fixed, with a main monowheel, fitted with a hydraulic brake, placed at the pod-boom transition within a prominent fairing and assisted by a smaller nosewheel. [2]
The Marianne made its first flight on 19 September 1985 and received certification on 29 January 1987. [2]
There were plans for later versions: an advanced trainer with flaps and retractable undercarriage; a higher performance Marianne with longer span (20.9 m; 68 ft 7 in); and a motorized, self launching version. [1] [2] None of these seem to have been built before Centrair ceased trading after producing eighty Mariannes. [1]
The Marianne got mixed reviews at club level: its performance was good, perhaps somewhere between that of two of its best contemporaries, the Grob Twin Astir and the Schempp-Hirth Janus, the airbrakes worked well and its build quality and viceless handling were also praised. Criticism focussed on the rear seat, which was said to be uncomfortable with restricted views, and the difficult rigging and de-rigging procedures. [1]
Sixty-five Mariannes appeared on the civil aircraft registers of mainland Europe in 2010. [3] The September 2012 UK register lists two more. [4] Another is in Australia in 2018, at Southern tableland Gliding Club. [1] [5] [6]

The ASW 20 is an FAI 15 metre Class glider designed by Gerhard Waibel and built by Alexander Schleicher GmbH & Co. Its fuselage is nearly identical to that of the ASW 19, mated to newly designed flapped wings for the 15 metre Class. The prototype first flew in 1977. It proved to be a highly successful glider, winning several World Championships, and was still being flown at this level up to 1995. Developments along its production life included winglets, pneumatic turbulators, and wingtip extensions. It remained in production until 1990, when it was superseded by the ASW 27. 765 were built by Schleicher and a further 140 were made under license by Centrair in France.
The Centrair C101 Pegase is a Standard Class single-seat glider manufactured by Centrair starting in 1981. The design uses the ASW 19 fuselage with a new wing designed by ONERA, giving better performance than the German original.
The ICA IS-28 is a two-seat sailplane produced in Romania in the 1970s. An all-metal aircraft of conventional design with a T-tail, it was originally produced with 15-metre wings, but in 1973, production shifted to the IS-28B with 17-metre wings and numerous aerodynamic refinements. These included a smaller tail with decreased dihedral, decreased dihedral on the wings, and redesigned fuselage contours. This version first flew on 26 April 1973 and was subsequently produced in versions with flaps (IS-28B2) and without (IS-28B1). Around 100 had been built by the early 1980s, with a substantial number sold for export. On April 7, 1979, Tom Knauff and R. Tawse set a world record with the IS-28 B2 glider, covering a distance of 829 kilometres on a predetermined out-and-return course from the Ridge Soaring Gliderport in Julian, Pennsylvania.
The ICA IS-32 is an open class high-performance metal two-seat sailplane produced in Romania in the 1970s. A refinement of the IS-28B, it shared most of that aircraft's fuselage, mated to new wings and empennage. This new wing had a span of 20 metres, featuring interconnected ailerons and flaps, Schempp-Hirth-type airbrakes. It had no provision for water ballast. The monowheel undercarriage differed from the IS-28 in being fully retractable.
The Issoire Silène was a sailplane produced in France in the 1970s and early 1980s, intended primarily as a trainer. It was a conventional design of fibreglass construction in versions with fixed or retractable monowheel undercarriage. The aircraft featured side-by-side seating for two, with the seats slightly staggered in order to minimise fuselage width. French certification was obtained on 3 February 1978, and production began shortly thereafter at the rate of two aircraft per month.

The Mistral-C was one of the first gliders, designed in 1974 to the then new Club Class rules. It was based on the Strauber Mistral, a Standard Class glider flown a year earlier, but with a new wing and built from newer composite materials. Both types were designed and constructed in Germany.
