SZD-56-2, Diana 2: Newest 15-meter Sailplane

The technologically advanced SZD-56-2 Diana 2 will
soar on new wings next summer. Bogumil Beres, chief
design engineer of the Diana and owner of Biuro Projektowe
'B' Bogumil Beres, recently announced the design project
of a breakthrough Diana 2, featuring a curved wing
platform with a continuously varying airfoil and high-performance
winglets. The original Diana fuselage will be retained,
but with a lower drag fuselage-wing junction. The wing
loading range will be 6.08 - 11.7 psf. Most remarkably,
the Diana 2 will break the long-standing 15-meter glide
ratio barrier of 50/1 with room to spa forecast
performance includes a max L/D of 52/1. Krzysztof Kubrynski
Ph.D of the Warsaw Institute of Technology has created
the Diana 2 airfoils using his custom 3-D computer
software. Mr. Kubrynski has worked extensively with
Delft University's Prof. Loek Boremans, who has designed
airfoils for many of the latest German competition
sailplanes. The prototype Diana 2 wings will fly next
August. Diana 2's will be delivered in the Spring of
2005.

Interestingly I have one of the last special Air worthness
certificates that the FSDO's were willing to give without
special conditions! Such as where you can fly. Mine
just states 'Exhibition and Racing' with no restrictions
on where!
And when I lost it I was able to get the exact replacement
a few years ago. Must have been my lucky day!
