Abstract

With increasing span or wing loading, it becomes increasingly difficult to fulfill all CS22 certification requirements for airbrakes simultaneously. Aerodynamic forces upon Schempp-Hirth airbrakes usually create pilot control forces, which limit the size of the airbrake. A certain design of the airbrake allows to reduce the aerodynamic source of this force considerably. This also solves two safety issues: It allows the pilot to retract the airbrakes at high speed and also reduces the risk of self extension of unlocked airbrakes at take-off.
