Building an Experimental Wing Spar at Night

The lights are still on in our workshop as the hours of the warm summer night pass by; we’re building an experimental wing spar and reaching the next small milestone in our fs36 project! Many hours of planning and preparing the workshop have passed as we finally get to building the parts. However, before we…

fs36 fuselage construction

After three years of design work, the time had finally come: at the end of January, a decisive milestone on the way to the maiden flight was reached with the shell construction of the flying fuselage of the fs36 FlyByWire. As already mentioned in connection with the introduction of the fs36 (https://akaflieg-stuttgart.de/projekte/fs36/), we decided to…

A Mock-Up of the fs36

In the course of the fs36 project, we’ve had to design a multitude of partsto allow for the realisation of our concept. Since we are planning on using astandard fuselage, we must of course make sure that our parts will fit insidesaid fuselage. To this end, we built a fuselage mock-up at the Schempp-Hirth airplane…

Article Series fs36 – Wing Test Piece: 5. It Moves!

And now we are at the end of the article series on the fs36 wing test piece. After the state shown in the last article, the fin, flap, and flaperon were trimmed and adjusted to each other, allowing for full movability. Furthermore, all three parts were painted and are now shining with a coat of…

Article Series fs36 – Wing Test Piece: 4. Last Steps to Sealing the Fin

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…

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,…

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 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…
