B and C model have a modified airfoil (w/ boundary layer control, but it
doesn't actually make a noticable difference in performance), a modified
flap setting for landing ("chicken" setting at 38 deg insead of 55 deg for
the A model) and a different mixer for ailerons/flaps. The B model has a
reinforced spar to be able to carry water in the BL version.
B/C models have the canopy connected to a lifting instrument panel, a
modified canopy jettisson mechanism (huge improvement) and automatic
elevator hook-up. They come with a sprung wheel and hydraulic brake. The
cockpit has some more fairings and a slightly different seating position.

That's about it. The important differences are in the safety aspects of the
fuselage... All models exist also as a "L" version with 16.6m span of which
only the BL may carry water in the 16.6m version.

ASW20 "TW"


"Ventus B" a écrit dans le message de
m...
The only place I have found to research the differences between the
above ASW20 glider models is on the Sailplane Directory website. From
what I can tell the B model differs from the "A" by a slightly heavier
airframe, boundary layer control blowholes on the wing, a higher auw,
and different airfoil. And as far as I can tell the C model seems to
have the same airframe as the "A" except for a slightly modified
cockpit, whatever that means, and the same boundary layer control and
airfoil as the B. I also believe the B and C models have different
(less) positive flap settings than the "A". All are certified in the
experimental category.
Can anyone corroborate/elaborate? Also, where can I find
airworthiness directives/technical notes on the ASW20? They are not
available on the FAA website for this model glider.
