Diana Sailplanes Diana

The Diana is a single-seat 15-metre class sailplane. It uses a mid-wing cantilever monoplane with a T-tail unit. It has an all composite carbon-aramid-epoxy structure. The spar-less wing has plate airbrakes protruding from the upper surface only with full-span flaperons. The Diana has a retractable main landing gear with a fixed tail wheel. The wing was designed by Krzysztof Kubrynski using numerical flow simulation methods (computer programs of his design). It uses a profile belonging to the KL-002 family. Also, the leading and trailing edges do not follow any straight lines, necessitating a production process that depends heavily on CNC technology. The new wing offers considerably better performance at high speeds and better immunity from surface contamination. In October 2016 Diana's IP rights for the design were passed to Polish company AVIONIC, who announces number of changes to increase performance and comfort of the flight, calling the aircraft NG (New Generation). NG includes fixes and improvements for pilot comfort. ==Competition Awards==
