Having
flown the aircraft on 18 flights during average weather conditions with
a temperature range from 25 to 36° Celsius we have not achieved a
satisfying temperature of the engine controller unit.
Three weeks ago we have therefore decided to change to another
controller providing higher performance.
The new controller was shipped immediately from the manufacturer and we
were able to do the necessary modifications. Unfortunately, the size and
weight of the controller made some modifications to the engine
compartment necessary. These have been finalized in the meantime and we
will continue with the tests. Of course, we will report on the progress
in due time.
June, 2018 electro-Libelle
In
the meantime, we have been able to do more than 10 self-launching with
our electro-Libelle and have several hours of engine time in the air.
Numerous data were collected, which we evaluate for the optimization and
approval of the system. So we are currently still not satisfied with the
cooling capacity at the motor controller, because the power has to be
reduced after just a few minutes.
Here
are a few more details about our eLibelle:
D-KLIB

Congratulation to Fa. Shempp-Hirth
to maiden flight of the 15 m
version of the Ventus 3!
On the 9th
April the Std.Libelle 201 BE with the registration D-KLIB performed the
first selflaunch.
More than 50 years after the maiden flight of the Std
Libelle a new chapter of the Glasflügel history has been opened with a
new development .
On the 9th April the Std.Libelle 201 BE with
the registration D-KLIB performed the first selflaunch. The system uses
an electric motor with 20 KW driving a two bladed propeller with 1,25 m
diameter. For the team Hansjörg and Christian Streifeneder it was an
important milestone towards the certification of the system after 24
month of work. The layout of the concept was part of bachelor degree in
aeronautics of Peter Speidel which makes him a key person of this
project.
The weight of the “Electric Libelle“ is similar to a
Std. Libelle 201b with water ballast and the stall speeds are only
slightly higher than an unballasted Std Libelle. On take off the climb
with 2,5 to 3,0 m/s is very good and proved the calculations . The noise
and vibration are a lot less compared to the normal combustion engines.
The battery capacity provides a motor run time of up to one hour.
For the next few months the flight test program and
certification process will be done and we will continue with more
information soon.

12-14th August 2016.
It was a unique Glasflügel FlyIn at genial weather at the airfield in Saulgau
(EDTU).
More
than 200
participants were able to be there and visited with their
Libellen H-301, BS-1, Std.Libellen, Kestrels, G-604, Club
Libellen, Hornets, Mosquitos, Glasflügel 304 und Falcon the
birthplace of their gliders.
Five tow planes moved tirelessly the beautiful sailplanes
in the air and the glider
pilots were able to enjoy flying over the "home and the nice
country side of Swabia.
1st of July 2016
We proudly announce a new generation
Mylar seals
With
the Mylar tapes and sealing kits we provided our customers an easy
possibility to improve the performance and handling characteristics of
their aircraft.
These options we developed and improved now for over 30 years to meet
the requirements of the market and technology to set new standards. And
now we proceed this tradition with our new
super white Mylar which matches perfectly the color of gliders and
motor gliders with as well as the advantage of better bonding.
and we are pleased that we were able to
contribute
our part for this great new design.
30th anniversary of Glasfaser Flugzeug-Service located in
Grabenstetten
On
the occasion of our 30th anniversary located in Grabenstetten it was
a great pleasure to welcome friends, companions, favorors, buisness
partners, fly buddies and our staff including their families. On
21st November 2015 they came from the United States, Canada,
Hungary, Austria, Switzerland and from all over Germany to celebrate
this anniversary with us.
One of the highlights of the day
was the opening of a small „Glasflügel gallery“. The idea of a
meeting place within a „historical“ environment arose a couple of
months before when we were forced to renovate the adjoining building
due to a grave water damage. The result is a small museum displaying
exhibits and technical documents as well as a meeting area.
Special
thanks go to all helping hands, consultants and decorators as well
as our staff. Since anniversaries like this stand and fall with the
catering, we made a good catch by choosing Hahn Catering.
It
was a day of encounters and interesting talks and company directors
of several aircraft manufacturers, constructors, suppliers,
consultants, former employees and many friends were present.
The senior partner warmly welcomed the guests with a brief
review and outlook and opened the museum which displays the history
of Glasflügel as well as the transition into
Glasfaser-Flugzeug-Service GmbH in 1982. He highly appreciated his
family without whom those development wouldn’t be possible. Finally,
he wished all guests a great and interesting time in Grabenstetten.
Following
the banquet, all guests were able to have a look at the company
premises or ask detailed questions. After enjoying coffee and cake
the day slowly got to its end since some of our guests had a long
way home and the first snow started to fall.
We are sure,
our guests enjoyed this day as well as we did. Once again, we want
to thank all our guests for their attendence, the lovely gifts and
this successful day. Thanks a lot!
21 July 2009 Nimeta project – the
world’s largest single-seated motor glider.
After
2 years development and construction the time has come: The maiden
flight of the currently largest single-seated motor glider took
place on 21 July 2009.
The ordering party Bruno Gantenbrink
(YY) insisted to make the first flight of this project initiated and
financed by his own.
Nimeta is a motor glider with a
strongly modified fuselage and elevator Nimbus 4 as well as Eta wings.
With this project we realized Bruno
Gantenbrink’s dream of a single-seated Eta. The challenge of this
project consisted in uniting the two motor glider types due to the
entirely different mechanics of wings and fuselage. Furthermore, we have
redesigned the fillet wing fuselage and enlarged the fin by 20
percent.
The engine system has been completely
adopted from Ventus/Nimbus and has been set by SHK.
After the today’s two hours maiden
flight Bruno Gantenbrink was highly pleased with the quality of his
new airplane.
We wish Bruno many successful
flights!
07/2009 Libelle pilots succeeded
nationally and internationally.
We congratulate Tobias Welsch on
winning the German Club Class Championship in Winzeln. Tobias placed
first just ahead of Arndt Hovestadt, Jens Becker and Christian Lang
- all on Standard Libelle.
This result represents the ongoing
great popularity of Standard Libelle. After all, 12 of the 41
participants competed on the type Standard Libelle.
Furthermore, we congratulate Volker
Sailer (Standard Libelle 203) on placing first at FIA World Junior
Gliding Championship in Club Class.
03/2009
Varnishing Edge 540
The last weeks we have been quite busy
with modifying and varnishing Matthias Dolderer’s Edge 540 whereby
he will compete in the Red Bull Air Race from this year on. At the
official roll-out in Tannheim on Saturday, March 21, he gave the
present company an idea about the performance of this plane. We wish
Matthias Dolderer and his team a successful and safe season.
From this year forward the BL-formation
has found its new home in Tannheim. Next to accommodate the BLs, the
newly-built Hangar 4 enables us to expand our maintenance business
to planes until 2t. The pilot-friendly and positive environment
allows continuing the further developments of our activities.
Details to follow shortly here.
From
4-13 July
2009 there will take place for the third time a Standard Libelle contest at Aero-Club
dŽIssoudun (LFEK). For more information and registration please click

- ETA Tuning
Currently we prepare
Hans-Werner Grosses' ETA glider (works number 1) for the new gliding season. Besides the
usual maintenance and polishing works we will carry out some small aerodynamical
refinements.
In
addition, the last year constructed yaw spoiler in the new outer wing with Maughmer
winglet has been revised and newly set. This yaw spoiler works based on the principle of
the top and bottom surface Schempp-Hirth type airbrakes. The yaw spoiler is electric
powered and supports the too little effect of the yaw rudder. After testing for almost one
year Hans-Werner Grosse is highly pleased with the renewed support of the yaw rudder and
which he would not want to miss.
Christian Walliser successfully
passed his journeyman examination
On 31
January 2008, Christian Walliser successfully passed his journeyman examination.
Our congratulation!
Since September 2005, Christian Walliser from Pfullingen
has been trained by our company as a light aircraft constructor. Himself glider pilot at
aviation club Reutlingen, Christian passed a carpenter examination before. By training as
a light aircraft constructor his childhood dream came true
Wing molds for Extra EA300 SR
Besides several other molds in 2007 we produced the wing molds for
Walter Extras' newest aircraft namely Extra EA300 SR. This aircraft, especially produced
for the motor sports competition Red Bull Air Race, originates from the single-seated EA
300 S. However, the wings have been a complete new construction. Using our milling
technology we were able to produce the negative molds for wings, spar, fins and aileron
within a few weeks. The high-precision molds guarantee to keep the aerodynamical basic
layout as well as to reduce the weight through its high accuracy of fit. That all that
effort pays off has been well demonstrated by Nicolas Ivanoff at the last race in 2007 in
Perth.
Wing molds for Concordia project
As already mentioned in several journals, we are also involved in
the Concordia project. Accordingly, the complete wing molds have been produced on our
milling machine. After putting together and surface sealing the molds were shipped to Dick
Butler to Tennessee. In the meantime the wing frames have been made over there. At the
moment the spar bars are being produced.
