In gliders scheme duck used very rarely, and each case of its application deserves travels special attention. This time the choice fell on the machine so remarkable as Aviafiber Canard 2FL Swiss company Avifiber (the brainchild of a Hans U. Farner, a graduate engineer and university professor) the end of the 70s. 2FL belongs to the class of ultralight aircraft at the start of the feet. As a glider, but with a rigid wing. These tricks allow such documents do without getting to pilot that allows access to anyone who wishes to fly without bureaucratic red tape. At the start of the pilot runs on its feet after the separation pulls his legs inside the fuselage, rotated horizontally, the bottom hatch (and lantern above) is closed for streamlining the fuselage. Planting can take place either at the ski under the fuselage, and the legs of the pilot. The main wing is placed above the fuselage on the two profiled pylons, which are mounted in the middle span of each polukonsoli, forming a closed triangular frame, which also serves as a vertical tail surfaces. The main purpose of such tricks - to make the wing as far as possible from the area of the bevel of the horizontal tail surface flow in undisturbed air, which is especially important at high angles of attack. Construction - fiberglass to form in the matrix of the skin and spar fiberglass laminate, with extensive use of foam filler Styrofoam. In the future, planned to use Kevlar fiber, and thus save two-thirds of the weight of the structure. For transportation wing machine travels is broken down into three sections by 4.8 meters, which was convenient to lay on the roof of the vehicle or trailer. Control system - mixed. Longitudinal control, pitch - balancing as gliders, the pilot changes the shifting center of gravity design. Cross - using ailerons and tselnopovorotnogo PGO (PGO each console could be rotated (or warp - in the original twist) to 5 degrees relative to the longitudinal axis of the machine) on the vertical tail mounted brake pads to control the rate of descent. In general, that such intricacy of management and decided the fate of the machine. In one of the missions of its creator was killed, because of the failure of the control system (the pilot's seat was located on the rails, shifting in which the pilot to adjust the position of DH during takeoff chair slid on rollers, moving beyond the allowable travels CG). After the accident, the co-owner of the company, travels Comrade H. Bucher bought back previously travels sold several gliders (4 kind of like), and tried to fix a design flaw, and resell them. But took place another incident finally ruined the reputation of the design, and Canard 2FL has sunk into obscurity. A copy of the airframe remained in the Swiss Museum Lucerne Transport Museum seems to me nothing constructor with balance control to play, and even the professor. Would put the CHR as a control surface for pitch and grief would not know. Although maybe he came from what is higher truths, no longer ask for the reposed. Structural travels weight - 59 kilograms. Wingspan - 13.5 m Wing area - 13 sq Length travels - 4.8 m. The minimum rate of decline - 0.6 m / s Aerodynamic quality - 31 Top speed (Vne) - 100 km / h (ie no longer travels for crash) Source : http://www.nestofdragons.net/rigid-wing s-overview / footlaunch-listing / canard-2fl.a spx
