Conventional high-lift systems are used for lift augmentation during start and landing operations of the majority of modern transport aircraft. Besides this, they have limited functionality during the rest of a flight mission. A possibility to provide more functionality is the use of single flap systems, that enables differential flap setting. For the implementation different technical realization can be used. In addition to dropped-hinge kinematic and fail-safe actuators, this paper presents various concepts for a novel safety device, which is integrated into the track linkage kinematic. For the so called flap track brake (FTB) an integration into the carriage is conceivable. The main task of the FTB is the prevention of flap skew in failure cases. Therefore different concepts are presented and discussed. For carriage integrated concepts a VDI 2225 like evaluation is conducted. The use of the FTB requires an adjusted drive system, which actuates every single flap with an independent and redundant electrical power unit. For investigations of the FTB and drive system in early development stage a co-simulation can be used to gain early results. Therefore the drive system can be modeled in MATLAB/Simulink and the flap kinematics are emulated in MSC/Adams.
