Asw-20 models ?

[Lars P. Hansen]

Hi all,

I know this has been asked before, but I seem to have forgotten where I
put my memory :-) -And www.deja.com was not really useful:
Could anyone point out the differences between the different Asw-20
models (a,b,c,f,..) and the pros, cons and possible gotcha's of these
models?

Thanks in advance,
Lars Peder

Lars:
ASW20A -built by Schleicher - first production run
ASW20B -built by Schleicher - Modified airfoil and turbulator jets in
wings
ASW20F - built by Centrair (France) under license
ASW20FP - built by Centrair - first glider to use winglets

letter L appended means additional span is capable by installation of
wing panels at wing tip

There are more nuances but that is the basics of it.

We went through the ASW 20 lineage about a year ago. Here's a quick
outline to fill in:

ASW 20 (aka "A" model) the original "20" appearing in 77-78.

ASW 20 F(P)(L) "A" model 20s built under contract by Centrair of France,
builders of the Pegase and Marianne. "P" stands for pennes--winglets, and
"L" for long (16.6 meters).

ASW 20B the first of these appeared at the Worlds in Hobbs in 1983. They
were "A" fuselages with a new turbulated, heftier and heavier airfoil.
These prototypes were followed up by a production run that included an
improved fuselage (disc brake, intergral canopy instument panel...) Max
gross was upped by 156 lbs over the "A" model.

ASW 20C incorporates the same airfoil and fuselage as the "B", but the
wings are lighter. Mac gross downrated to 1000 lbs.

All versions of the 20 came with an L option for 16.6 meter tips.

The A model is the best handling of the bunch, but is prone to flutter.
Many A owners have installed retro kevlar ailerons and/or a control rod
dampner to stop flutter.

Though there are airfoil differences between the As and B/Cs, the most
noticeable performance difference comes in landing. The A has 55 degrees
of landing flap, 15 degrees more than the B/C. All three models climb
well, and at equal wing loading, the B/C performance improvement only
becomes noticable at high speeds.

My choice would be a B. It's a very solid glider.

The Soaring Society of America offers a searchable CD ROM with a
information on hundreds of sailplanes, including the ASW 20. Go to
www.ssa.org for ordering info. It's a great resource - buy one and
encourage them to continue updating it. Or you can ask any SSA members
you know if they have a copy, including the printed form that was
mailed to all members a few years ago.
