Discus CS grounded in France

Chris OCallahan stated

'...quality control broke down at the Chechnia factory.
The question is 'For how long and to what degree?'
Two gliders from the same factory breaking up in flight
in a single season quality control broke down at the
Chechia factory. The quesiton on my mind is,
'For how long and to what degree?'

Two gliders from the same factory breaking up in flight
in a single season deserves a factory explanation.

Dear Chris,

Maybe the WingGlueMan needs reassignment to
clean shop or answer telefunken;

or

a Beer On The Job rule of not more than 2 grossestein
biers every hour needs some clearminded consideration.




Dancing on clouds,

Keep it up!

Got this second hand info. The scenario goes something like this

Workers A, B & C don't spread enough glue (cabacil) onto the wing just before
the mating process.

Inspector D, didn't feel it was necessary to have a look, saying, "you guys
have been doing this long enough to know what your doing"

Pilot E, has a rude awakening. He may have just completed a loop when things
started shedding from his sailplane.

In the recent post, there is a reference to a "Chechnia factory". For
clarity's sake, and nothing else, I think the writer meant the Czech Republic.
Correct me if I am wrong, I have been know to goof before.

Cheers, Charles

I believe that most of the CS's were built by Orlican in Chocen, CZ.
Some of the later ones were built by Schempp-Hirth, Vyr.Let.S.R.

There is a company using the Discus BM Wing for a very new design
called the Carat (Motor Glider). It is manufactured by a company in
Slovania called AMS Technoflug and uses a front enging with forward
folding propeller. I assume that they are manufacturing the (Discus
BM) wing design in Slovania. I understand that they are known for very
high quality work... they build many of the DG Gliders.

Now I am confused, Eric wrote
In composite construction, there is no "glue": the resin permeates the
other material (glass, carbon, Kevlar, etc), and the material
properties depend on this. There are layers of the fiber, but they
aren't glued together like the wood layers in plywood.

How is the fiberglass layer bonded to the foam core, if it isn't *glued* with
the resin? I thought you were making the distinction between several layers of
fiberglass cloth, as in a fuselage and fiberglass cloth/ foam core/ fiberglass
cloth, as we find in the wing.
I thought you were saying that plywood wasn't a *composite*, because it didn't
have a core, so therefore couldn't be considered a composite, but now you are
saying that 3 layers of fiberglass is a composite, but 3 layers of wood isn't.

Some of the plywood we use in our sailplanes is made up of mahogany / poplar
core/ mahogany. Sounds like glass /foam core/ glass, with a change in
materials, doesn't it?

Nope, my goof. Finger flutter.

Schempp-Hirth, Vyr.Let (Vyroba Letadel means Airplane factory) is the
new name of Orlican

Cheers

All natural timber is a composite, even by Eric's definition. It's fine
structure is a composite of fibres and glue, just like GRP.

Cellulose fobres in lignin isn't it?

"The next time someone sneers at a wooden sailplane, remind them that it is
made of a unidirectional reinforced laminated composite material consisting
of micro-tubular fibres embedded in a long chain polymer matrix and having a
near infinite fatigue life."
