As long as I can remember, I always enjoyed drawing airplanes and other technical things, primarily vehicles. Later, some people asked me to prove the advantages of my ideas. In the meantime, I actually often start with calculating and even the first lines are already based on this. So it was in this case. As usual, and as probably many contributors do, I began drawing with a pencil on paper. But this time, it turned out a bit complicated with the details of the slender wing so I switched to CAD(rawing) very soon. So it's kind of computer generated and I dare posting it here. Meister Schwarzrock (black robe) is intended to be a standard class glider with an exceptionally high aspect ratio of more than 37. In order to deal with the high wing loading resulting from less than six square meters of surface the wings are to be equipped with Wortmann flaps for slow flight. Eppler's E-403 airfoil has been modified for better high speed performance by reducing camber and shaping the pressure side for more laminar flow. As XFoil even did not produce lift coefficients much higher than the needed value, the fully deployed flap is to unblock slots that allow air to flow around its nose from the pressure to the suction side in order to re-energize the boundary layer. At the wing tip, leading edge radius has been increased to overcome low Reynolds numbers and the nose is drooped a bit for higher maximum lift. The flaps are coupled with the stick. Only when they are fully deployed or retracted the plane is controlled using the all-flying tail alone. The elevator even has to move in opposite direction when the flaps are being pulled out or pushed in again. This regime is quite similar to the Hungarian KM-400 that was exclusively controlled by flaps and had a fixed elevator. The slight gull-wing shape is not artistic but results from the fact that the pivot of the Wortmann-flap is 30% below the chord line and it seem desirable having all pivots on a straight line in spanwise direction. To fully take advantage of the small wing surface the drag of the fuselage has to be minimized as well. The cockpit is tightly stretched around a pilot in a canvas chair position. The wheel does not only look so big because of its dimension, but also because the body is so small. The "back window" which is untypical for a single-seater, is also stolen from Kesselyak Mihaly. However, I was always a bit annoyed by not being able to look around when sitting in the "Pirat" or "L-Spatz" and much more liked the view out of the double-seaters, even when flying alone. Grapher was used for airfoil modification, basic aerodynamic data were gained with XFoil, lift distribution has been calculated with a CVI-code (C++ for virtual instrumentation). Some rudimentary flight mechanical and stability calculations were done with Grapher again. The whole drawing is all Grapher up to now, a slightly Excel-like program, so it's basically x-y-plots in diagrams with an ASCII data sheet behind it. A rendered 3D-version is to come sooner or later. Meister Schwarzrock is the raven in the ferry forest of pre-1989 east German children-TV, most remarkable the big glasses on his big beak ...
