Abstract:
Regarding environmentally friendly aviation, one key technology is the electrification of primary flight control systems by using jam-tolerant, electromechanical actuators. The required safety can be achieved by the integration of a pyrotechnically actuated mechanism in the drive train which disconnects the electromechanical actuator in case of a mechanical jam, so that redundant, electromechanical actuators are able to maintain the control function of the system. This paper describes the testing procedure during the development of such a pyromechanism including several pre-tests, the characterisation of the dynamical behaviour during the decoupling processes and robustness tests. The pyrotechnically actuated mechanism performs decoupling processes within shifting times shorter than 5 ms at compressive or tensile preloads up to 40 kN.
