Abstract:
The present communication is aimed at proposing a modelling approach for the comparison of energy losses within hydraulically and electrically supplied actuators. It is applied to an aileron actuation for a single aisle commercial aircraft. An inverse simulation approach is used to calculate the power demand at aircraft power sources from the flight control surface deflection and hinge moment over a generic mission. The top level modelling of the actuators is based on bi-causal Bond-graph that allows determining the calculation structure for inverse simulation. The modelling focuses on friction in jack, pump and roller screw, on the electric motor rotor drag and copper losses and finally on the motor power drive conduction and switching losses within the power electronics. The simulation results are commented to point out the dominant losses, the very little influence of the mode of operation (active/standby or active/active) and the lack of interest for energy recovering.
