Article Series fs36 – Wing Test Piece: 3. Construction of Small Parts to Complete Construction Groups

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…

Article Series fs36 – Wing Test Piece: 2. Wing Skin Construction and Detail Design

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…

Articles Series fs36 – Wing Test Piece: 1. Reasoning and Mold Making

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,…

Aerotow Test fs35

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…

News on fs35 Flight Testing

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…

Flight Mechanical Model of the fs36

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…

Progress on fs35 Flight Testing

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…

The fs35 Takes to the Skies Again

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…

Progress on FEM Calculations for the fs36

Even though we still aren’t allowed to hang around our workshop, we’re still working intensively on our fs36 project. One section that had a lot of work put into it were the interface between strength verification and load calculation, along with the FEM model. These will be explained in more detail here. In the past…
