Stuttgart team

The Stuttgart team (University of Stuttgart, Germany) is responsible for Wing and Empennage Design and Manufacturing, and Control System.

Regarding wing shaping there are three major aspects to be considered. First its aerodynamic characteristics shall provide a high lift to drag ratio with good stall behavior. Second the wing weight should be as low as possible and third its construction has to be feasible. To determine the detailed layout an iterative process is used. First aspect ratio, taper and estimated total lift coefficient for a fixed design speed and chosen profile are predefined. These values define the exact wing layout and are fed to a analysis tool where a new wing lift and drag coefficient are computed. For AREND UAS we’ll have a relatively thick double tapered wing with a high aspect ratio and high lift devices such as plain flaps.

The exact design of the empennage is still in process. But we will have a twin tail boom and an  inverted-V empennage.

The UAS is steered by a total of 6 servos. There is one servo for each of the two ailerons, one servo each stabilizer (vertical and horizontal) and one servo for each of the two plain flaps. The servos for the primary control surfaces are high speed servos.
