Diana 3 - Aerodynamic Masterpiece

Indeed this sailplane is an Aerodynamic Masterpiece.

Diana 3 is the high-performance 18-meter span sailplane, created to achieve the highest standard of aerodynamic design in her class.

​

Its performance characteristics in the air are to be better than any other 18-meter class sailplane.

​

Very high gliding ratio about 55:1 giving the pilot

the comfort of the flight.

​​

Low descent of 1.4m/s at speed of 200km/h and enormous climbing capabilities at low speeds making Diana 3

an excellent competition and cross-country sailplane.

​

New wings

New Diana 3’s wing profile is a high-tech mile step into the future thanks to nowadays simulation software. There are some unique and more advanced aerodynamics solutions in it than in the previous project.

A good example is a different pressure distribution on the wing profile than well-known solutions in other gliders.

This means different properties giving better characteristics for lift force, better climb rate, and more resistance to dirt, bugs, and rainfall.

​

Centre stick.

A very short but important message here:

'No more side stick in Diana 3'

​

This sailplane has been equipped with a very common and popular center stick which is good news for pilots who prefer the usual solution.

...History

​

The idea for a new KKB glider came during the Grand Prix competition Chile 2010, where several Polish and Czech glider pilots suggested to combine the Diana-2’s wings with the KKB fuselage.

Doctor of aerodynamic, Professor Kubryński designed a completely new wing for the KKB fuselage with a span of 18 meters.

After a couple of years first prototype was created. Towards the end of 2016, load calculations were completed, fuselage load tests were carried out, and in January 2017 a load test of the wing was performed to finish the finishing work on the glider.
 

​In December 2017, our company "Avionic" purchased the rights to the glider and given the name to the sailplane - Diana-3.
