Recently, the first ship set of the load sensing drive strut for the A350 XWB flap system, developed and manufactured by Liebherr-Aerospace Lindenberg GmbH, Lindenberg (Germany), was delivered to the Airbus system test bench in Bremen. The set consists of a strut for the flap stations 1 and 4 and the associated harnesses. This mechanical-electronic component is installed four times in each aircraft.

The load-sensing drive struts signal to the high-lift controller if there are unacceptably high loads between the actuation system and the flaps, which may occur in case of certain faults. The controller then causes the flap system to enter the so-called fail-safe mode, by turning it off. Airbus simulates one wing side of the aircraft on the system test bench in Bremen.

At the same time, the qualification test bench at Liebherr-Aerospace in Lindenberg has been successfully put into operation with a load-sensing drive strut, in order to conduct the usual tests for technical performance, endurance, fatigue, vibration and environmental sustainability.
