Cirrus vs ASW

The Pegasus was also a success because of the lessons learnt when producing
the ASW20 under licence.

The Pegasus is clearly an unflapped version of the ASW20, just as the LS8 is
an unflapped version of the LS6.

Yes.

Clearly Centrair treats its American customers in an indecent way, and
this is a major problem for them. Am I surprised of this lack of
seriousness? Not really, knowing all those stories about the Marianne
and other Centrair fiascos. To extend the discussion one of the main
problems in France is the poor state of small industries (what we call
PME). Conversely Germany has a very strong net of such small industries,
which innovate, export, etc. The Pegasus was a success, not because of
Centrair, but because of the wing studies by public researchers, and
subsidies by the French glider associations. When all that run out, so
did Centrair.

The Pegasus has a completely different airfoil (developed by the French
research institute ONERA) than the Schleicher gliders, and it's the reason
that a Pegasus has a significantly higher performance than an ASW19. But for
the rest, I agree :-)

Hi Bert,

are the Pegase airfoil coordinates available somewhere?

I'd really be interested in a closer look at the Pegase's airfoil -
because I usually flew my ASW-20 with flap setting 3 (=neutral flaps)
while thermalling and got the impression that this setting would make
the 20 a very high performance standard class glider. In my opinion
the FX 62-K131 is a very good fixed wing airfoil.

I have no idea how to get hold of the airfoil coordinates...

Yes. But then the Marianne should have been a greater success from the lessons
of producing the Pegase.

No, this is not true. The fuselage is the same more or less, but the wings are
completely different, with a new design, obtained by public researchers at
ONERA. This has been hashed and rehashed many times. I suppose you will not
object to the point that the wing design is by far the most important point
in the design of a glider, and that almost all performance and handling comes
from that.
