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…

Operation of the fs36’s Flaps

Our newest project, the fs36, will be a fly-by-wire sailplane with Fowler flaps, an idea first attempted by the Akaflieg Stuttgart with the fs34 Albatross. Generally, sailplanes with a variable wing area are designed to achieve an advantage in thermalling by increasing their wing area, while during high speed flight, the flaps are raised, giving…

Numerical Analysis of Wing-Fuselage Joints for the fs36

Just last summer, Caroline, as part of her Bachelor thesis, ran some tests on a reference configuration of a wing-fuselage joint for the fs36. Said configuration didn’t use any specially designed joint. A CAD model for the joint with the flaps raised and lowered respectively were created. Nets were generated and both Euler and RANS…

fs36 FlyByWire

A new dimension of Performance and Safety! With this in mind, a new glider prototype is being built at Akaflieg Stuttgart. The most important feature can already be recognized in its name – FlyByWire: For the first time we want to do without the usual mechanical flight controls used in small aircraft construction. Instead, the…
