=BKB1-A, AoA>30 deg.
Well the BKB and Bekas are two different machines. He participated in the design and construction of the BKB but the Bekas was all his although all he did was stretch the spar, substitute a Wartmann airfoil, and change the pod shape. When they tried to fly it in the 60s it fluttered and crashed so he apparently screwed up the spar.But Kasprzyk did not design the BKB Bekas glider that started all of the so called Kasper Wing designs.
He was was a very good and safe pilot and did an excellent job promoting the design and demonstrating its performance potential.
=some time ago we have got a drawings (9 x 1) m ! of BKB1 AR=10 gliderWell the BKB and Bekas are two different machines.
PS=I can not install short video with last tragic fly of BEKAS-N !?(619 kB)=some time ago we have got a drawings (9 x 1) m ! of BKB1 AR=10 glider
which was modyfied by Witold Kasper into BEKAS-N ("narrow") with AR=15 .
=BKB1-A =modyfied and explored by W.Kasper (triangle wingtip extention+stabilizers
+greater rudders =full AEROBATIC wit NO altitude restrictiones )
=BEKAS1-A =1.2 m chord ,restored in Poland,
after exellent car towings ( from 3 m high was flown circa 300 m !)
was destroyed in first, 22 sec.aerotowing (WILGA !)
this thri tailles glider have NACA8-H-12 airfoil.
=NOT alived... (inner distorsiones)And the pilot?!
