Lange news - H3 and beyond

[Dave Nadler]

The DLR-Lange H3 project is officially announced, details here:
http://www.lange-aviation.com/htm/english/news/news.html

The 23-meter wing molds will also be used for
the new 23-meter Antares and Schemmp-Hirth open
class machines.

The H3 max takeoff weight: 1.25 metric tons (2756 lb),
provides interesting wing-loading. Axel Lange reports
that H2 thermals well at 825 kg (1819 lb, a mere
13.1 lb/ft2 wing-loading).

Further detail to follow on Lange and SH web sites,
first orders have been accepted for both machines ;-)

See ya, Dave "YO electric"

Dave, are those Streifeneder molds?

Thanks, Bob K.

These molds were not made by Streifeneder.
Very fancy molds - super accurate, temperature
stable, with heating systems for high-temp
curing in the molds (mold halves join for closure
and first high-temp cure).

See ya, Dave

I heard they NC cut the molds with a sawzall.........;)

PS..................we use Mr Sun to post cure our parts, got them up
to 125-140 degrees!

There's no sun in ZWB, at least not in winter !
No sawzalls either, just gnomes with NC machines...

One might mention that these wings are going to be used on the
next-generation Nimbus, too.

Right, you did... - mea culpa.

The Antares has a really good wing - I guess it's proving right now
that electricity is the power source of the future. With 23 meters
it's probably going to be the ASW-22 and Nimbus-4 killer.

BTW:
Lots of really exciting new gliders approaching - anyone else who's as
curious as me about the new ASx-32 and ASx-33? :)


Cheers

A disputable logic. :-)

Think he meant to say that "electricity provides the funding
source..." :-)

At least the soaring community gets new wing molds.

Anyone know if the ASH-30 is ever going to come off the drawing
board...? It seems the EB-28 and EB-29 have the "long wing" open
class locked up. The Antares/Nimbus (5?) shorter wing with reduced
wing area at 850kg may prove to be the right combination for Uvalde
2012.

Soon... :)

Schleicher is working on a nice module system at the moment.
The 32 will be the open-class single-seater version of the 30, and the
33 will be a combination of a slightly shorter 30 fuselage with a 20m
wing very similar to the 31.

I personally think that the wing of the 30 is a tad too bit, not
allowing high-enough wing loadings. But time will tell...

The Antares wing, stretched to 23m, with an aspect ratio of 38.5 and
max wingloading of 58kg/m2 (11.9 lb/ft2) ought to be unbeatable in
good hands at Uvalde.

Corollary to the question: anyone have an update on Dick Butler's
Concordia project? I seem to remember something about a 13lb+ wing
loading and 28m of wing...

Dick has closed the two inner wing panels, and he's
now back at work on Concordia after Hobbs and
a bit of fun flying (Hobbs was *not* fun). Concordia
is one amazing project !

See ya, Dave "YO electric"

In Szeged, Prof Loek Boermans said that the maximum wing loading of
the Concordia will be 62 kg/m2.

The name of the new "Nimbus 5" is Quintus!
