For conventional aircraft, the high-lift and main landing gear systems are hydraulic/electric consumers with high power demands. The paper shows how the supply systems of these can be combined to save system weight and cost for future more electric aircraft. This is made possible by multifunctional hybrid PCUs (MHPCUs), which can be used as electric motor pumps in addition to the conventional high-lift motor mode. A proposal for the architecture of this concrete center system as well as for the hydraulic drive train of the MHPCU is given. In the second part, the operating strategies and their control concepts are described. This is relevant for the main landing gear operation and the power transfer between the MHPCUs in the event of a failure. By means of system simulation, the operating strategies are tested and basic requirements are verified.
