Dear Glasflügel-friends,

We want to keep the Glasflügel-glider attractive. Of course, winglets are also used for this purpose. To investigate the interest in such kits for the remaining models, we started a survey. With the results we can estimate whether the development and approval costs in relation to the number of units are in an acceptable range.

So you would help us a lot to take 2 minutes to answer the three questions.

to the survey

Thanks.

We are still available for you!


Despite the current worldwide special situation due to the COVID-19 virus, we are still able to maintain our operations for you.
Maybe the processing times are sometimes longer due to the special safety prcedures. However, we strive to limit this to a minimum of a few days.

We all hope that this special situation will end soon.
Let's use the time to make plans and prepare for the first flight after Corona. Anticipation is the most beautiful pleasure! Stay healthy!

E-Libellen Info: 

Dear parties interested in the Electric-Libelle:

Today we would like to inform you on the development status of the Electric-Libelle.

Our concept of modernizing the Std. Libelle and implementing an electric motor system

 capable for self-launch without any difficulty, really met our expectations, at least in principle.

However, a number of modifications of motor and controller were made to reduce temperatures

 and to increase run-time of the engine. Unfortunately, these changes had side effects we actually

did not expect as there are significant interferences. Since February this year we were

working - together with electronic experts - to overcome these electromagnetic disturbances,

 but up to now filtering measures could not solve the problem.

Currently we are trying to find new components which do not create such disturbances.

 We are afraid that the required changes might result in a number of modifications and

 that we will need to create new details in order to realize our concept.

This means for us, more or less, to start all over again, which will require lots of time and efforts.

 Nevertheless, we have decided to hold on to our goal, but we are unable to guess on the timeline to the goal.

 We will keep you updated from time to time.

June 15, 2019  was a successful day for the Crystal Squadron.  Our special congratulations to Karl Sommer

and his fifty year old sailplane Libelle H-301 # 110 for their 200th diamond distance flight! 

For info: The “Crystal Squadron” is a group of soaring pilots flying out of Crystalaire airport in Llano, CA.

The group follows the Henry Combs tradition and philosophy by flying straight out as far as possible on a regular basis

 each Saturday and sometimes on holidays between late-April and mid-September.

 The only requirement for membership in the Crystal Squadron is to fly straight out from

the Southern California Soaring Academy (SCSA), Crystalaire Airport

       Starting on June 12 until June 16, 2019 we will come together in Bad Saulgau to fly together, to share recollections and

 experiences and - may be - to get some news.

        For all of you not yet registered, here is the webpage of the organizers: www.glasfluegel.net

Hanko, Christian and your Streifly-team

New fun in old plastic gliders

According to this motto for the second time a competition for old club-class gliders was held in Australia. By the rule change for the club-class by the IGC most of the relatively inexpensive gliders were culled out of competition flying. To reestablish a competition platform for these gliders the team around Nick Gilbert and Adam L’Anson has created a Grand Prix with the handicap 1.0.

This was the starting point for Formular 1.0 GP which became instantly the most popular gliding contest on the fifth continent. The tracking system, which was developed especially and the contest software gave for the first time an overview of the standings at all times during the race, much to the exaltation of the spectators and crews. Last year 26 gliders competed in two groups which were mixed through depending on the performance of the day. Due to the great demand this year 39 competitors were admitted in three groups (10 Std. Libelles and 4 Hornets, aside LS1, DG100, Jantar and Cirrus). As the starts for the groups were separated there were no huge gaggles and a fair result was possible without huge efforts. Average speeds topped 136 km/h although water ballast was not permitted and so it was exiting to follow the race.

 Ingo Renner was engaged for patronage and handed over the prices on final day:

1.       Ben Loxton                         Std. Cirrus

2.       Lumpy Paterson                 Std. Cirrus

3.       Andrew Maddocks            Hornet

This outstanding event came to our attention as well. As it is a platform to prove the performance for older gliders like the ones from Glasflügel, we were happy to support the event as sponsor and as competitor. Recommendable!

Status Report on the Electro-Libelle

 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

 

Motor-Power

20 kW cont.

Propeller diameter

1,24 m

Akku-System

in the wing

Akku-Energie

6,2 kWh

Akku-Mass

~45 kg

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.

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!
