The CVV-4 Pellicano (English: Pelican ) was a single seat Italian glider designed for a competition to select an aircraft for the 1940 Olympic Games. The DFS Olympia Meise was preferred to it after the trials in Italy in 1939.
The CVV-4 Pellicano was one of two Italian designs competing to become the preferred Olympic glider at the 1940 Olympic Games. Had they happened, these Games would have been the first to host a gliding event. It was planned that all competitors should fly the same 15 m (49 ft 3 in) span type and designs from Germany, France, Italy, the Netherlands and the United Kingdom were evaluated for the role at Sezze in Italy in February 1939. [1]
The Pellicano was designed by the Centro Studi ed Ezperienze per il Volo a Vela (CVV) of the Politecnico di Milano, who had a tradition of glider development. A typical late 1930s glider, it had an all wood frame and was covered with a mixture of plywood and fabric. The Pellicano was a mid-wing monoplane, with significant dihedral on the centre section forming a gull wing, rather fashionable at the time. In plan the wing was straight tapered, with rounded tips. It was built around a ply covered D-box leading edge with fabric covering aft. Ailerons occupied the whole trailing edge of the outer, zero dihedral section and there were mid-chord airbrakes, opening above and below the wings, towards the outer end of the centre section. At the wing root the plywood skin extended to the trailing edge. The choice of NACA rather than Göttingen airfoils, the former less cambered and so faster, was a little unusual. [1]
The Pellicano had an oval cross-section, ply skinned monocoque fuselage tapering rearwards. The narrow chord fixed rear surfaces were ply covered with the tailplane mounted on top of the fuselage and forward of the fin. The control surfaces were fabric covered and the rudder, broad and deep, moved in a gap between the elevators. The pilot sat ahead of the leading edge of the wing under a multi-piece canopy with a rather upright windscreen and which merged into the upper fuselage aft. There was no landing wheel, just a skid which ended under the wings and a very small tail skid. [1]
The Pellicano took part in the olympic competition held in Sezze Littoria, near Rome in February 1939, have only just made its first flight and with little further testing. [2] It was not successful as the German DFS Olympia Meise was chosen for the Olympic event and, though this did not take place, went into post-World War II production in several European countries. The Pellicano remained a popular aircraft locally though production numbers are uncertain. [1] Another source says that only the single prototype, I-ABNJ, was built [2] and it the only one on the official records. [3]

General characteristics
Performance
The Arsenal Air 100 is a French single seat competition sailplane produced in the 1940s. It sold in small numbers but set several records, still holding the world absolute solo glider endurance record of 56 h 15 m.
The Maeda 703 was one of the first indigenous Japanese gliders, a high performance single seat aircraft which first flew in 1940. Three were built, two with gull wing wings; one of these set a national endurance record in 1941.
The CVV-6 Canguro was a high performance two seat glider, designed at Milan Polytechnic University in 1940. A small batch was ordered for the Italian Air Force but few were delivered; more were produced after World War II, becoming the most common Italian gliding club machine. Some were still in use in the 1980s. In 1954 a Canguro came second at the World Gliding Championships at Camphill Great Hucklow, Derbyshire, England. One was modified into a powered aircraft, at first with a piston engine and later with a turbojet.
The Ciani EC.37/53 Spillo or SSVV EC.37/53 Spillo was a single seat competition glider designed and built in Italy in the 1950s. It had the highest aspect ratio wing of any wooden glider. Only one was built.
The CVV1 Pinguino was a single seat, high performance glider designed and built in Italy in the mid-1930s, the first of a series of gliders from the Milan Polytechnic. It did not go into production.
The CVV 2 Asiago is a simple, single seat glider designed and built in Italy in the mid-1930s, the second of a series of gliders from the Milan Polytechnic and the first go into production.
The CVV 3 Arcore was a single seat competition glider designed and built in Italy in the late 1930s, a development of the CVV 1 Pinguino. It participated in several national gliding competitions in the short period before the outbreak of World War II.
The CVV 5 Papero was a single seat competition glider designed and built in Italy in the late 1930s, a development of the CVV 4 Pellicano.
The CVV 7 Pinocchio was a single seat competition glider designed and built in Italy, first flown in 1952 though designed in 1940. Only one was built.
The CVV 8 Bonaventura was a two-seat competition glider designed and built in Italy during the 1950s. Fifteen were produced.
The DFS Rhönsperber, otherwise known as the Schweyer Rhönsperber or Jacobs Rhönsperber was a single seat competition glider designed in Germany by Hans Jacobs and first flown in 1935. For several years it was regarded as the best German sailplane and about one hundred were built.
The Aeronautica Lombarda AL-3 was an Italian sailplane, designed and built in 1939 to take part in the Olympic sailplane competition. It did so but was not successful.
The CAT 15 was a single-seat primary glider built in Italy just before the Second World War. Only one was constructed.
The CVT1 Zigilo was a single-seat, 12-metre-span (39 ft) Italian training glider designed and built in Italy in the 1950s. Only one was completed.
The CVT2 Veltro was an Italian competition glider built in the mid-1950s. Its advanced design incorporated a laminar flow wing, T-tail, retracting undercarriage and a reclining seat to reduce parasitic drag.
The Teichfuss Gabbiano was an Italian, one-off, single seat, high performance glider, designed by Luigi Teichfuss and flown in 1928.
The Teichfuss Cicogna was an Italian tailless single-seat motor glider designed by Luigi Teichfuss and flown in 1936.
The Teichfuss Sparviero was an Italian single seat aerobatic glider, designed by Luigi Teichfuss and flown in 1938.
The Zlín Šohaj series of club gliders began as a post World War II development of the DFS Olympia Meise. A large number were built in the 1940s and '50s.
The Oberlerchner Mg 19 Steinadler is an Erwin Musger designed two seat tandem trainer glider built in Austria and first flown in 1951. Several examples of this successful aircraft, which competed in the two seat class at two World Gliding Championships in the 1950s, were still flying in 2000.
