In this article, we will describe the final steps to completing the main part of the wing test piece, the fin. By now, a large part of the work has been done and the goal of a small wing with a moveable flap and actuator-driven flaperon seems to be within reach. While producing the small…

As hinted in the last article, the time consuming construction of small parts was just around the corner. From a production standpoint, the flap had to be completely built along with its bearing before we could continue with the test piece. The reason for this was the placing of the flap guide rails in the…

At the end of the last article, the largest parts of the mold had been completed, and now it was time to start building the structure. Even though it would have been best to start building after the detail design had been completely finished, the tight schedule did not allow it. The wing skins in…

During the last year, we built a test piece of the fs36’s wing. We will tell you about the whole process in a series of articles. Design work on our newest prototype, the fs36 “FlyByWire” is progressing quite well and CAD (Computer-Aided Design) work is becoming more and more detailed. During the whole CAD work,…

The time has come; the Akaflieg Stuttgart finally has its own towplane again! Last evening, the fs35 took to the skies with an ASK21 in tow. Thanks to its large wing area, the towplane lifted off early, almost at the same time as the sailplane. The tow was uneventful and didn’t pose any problems. During…

A year ago from today, the fs35 performed its first flight in Schwäbisch Hall. Many things have happened since then; the plane was ferried to Bartholomä, where it continues to be flight tested. After the first flights this year, we started with crosswind and headwind tests, which would prevent us from being too dependent on…

Apart from flight testing the fs35, we’re still hard at work on our newest project, the fs36. Fowler flaps, which are to be installed on the fs36, have only very rarely been incorporated in sailplanes, and therefore not a lot of experience has been gained on their use in the field. To deal with this…

We have good news regarding the fs25. A few months ago, we told you that the fuselage of the fs25 is to be repainted. Now we can show you the progress we’ve made. After hours of work, we finally got the fuselage ready for repainting. We then brought it to Heubach, where it would at…

Last week we told you that flight testing on the fs35 was to resume shortly. Now, we can tell you a bit about the progress we’ve made so far. We’ve worked on two separate fields: crosswind test and airspeed indicator calibration. In a crosswind test, the airplane is flown with crosswinds up to a certain…

Last Friday, after a long winter break, the fs35 finally took off again. Just as during its first flight, our little harpy impressed us with its stunning flight performance. This is the first time that the fs35 flew after its ferry flight from Schwäbisch Hall back in September and it is also the first time…
