The design principle of the Tair 5 Discus Launch Glider is to make the glider higher, stronger, and newer.
Aerodynamically, we adopted a more extreme design of fuselage, so that the drag produced by fuselage is extremely small. In this case, most DLG pilots can easily launch it to more than 210 feet. The airfoil of Tair5 has been optimized with 10 years’ effort. The performance in thermaling, light-thermal climbing, and penetartion achieves a new mile-stone.
After millione evenings with a beer and discussions, on a great occasion with a suitable guys (professional miller and students of aviation engineering) was produced the first fully molded DLG in Lithuania. The very first fully completed model with a large hope was given to one of the best glider pilot of Lithuania – Donatas Pampikas and escorted to the European F3K Championship in France. Expectation proved to be correct, Lithuanian Stream in Donatas hands took 7th place ….
Donatas flew with model which weight was 268 grams .Wing 127g, tail-set 12,5g and fuselage 37g.
In order to meet all 3 goals, the airfoil series Zone V2 designed by Gerald Taylow was chosen for the wings. It is a very thin and modern airfoil, and has excellend launch and ranging capabilities. A large speed envelope requires that the airfoil is able to operate with a variety of camber settings, and the Zone V2 is able to handle extra camber to slow down without becoming unresponsive. A slightly oversized horizontal stabilizer also helps maintain a larger speed envelope, and to make it more naturally stable. A special planform was designed to work in coordination with the airfoil series with optimization towards handling. With a wing area of slightly over 22dm^2, the Neos can work even the lightest lift. The wide tips allow you to feel the smallest bubbles of rising air, and in combination with the washout throughout the wing, allows the plane to turn in steep bank angles without stalling the tips.Read More
