摘要: In order to increase availability of hydraulic power from different electric power sources, the invention provides an apparatus (22) and a method for hydraulically powering at least one consumer (14) of a hydraulic system (12) of an aircraft (10), the hydraulic system (12) comprising:
a first electrical power source (A) and a first electrically driven motor pump (MPU1) electrically powered by the first electrical power source (A),
a second electrical power source (B) and a second electrically driven motor pump (MPU2) electrically powered by the second electrical power source (B),
and a hydraulic power generation control (26) which controls a supply of electrical energy from the first and second electrical power sources (A, B) to the first and second motor pumps (MPU1, MPU2). The invention proposes to determine the actual available electrical power (APA, APB) of each of the first and second electrical power sources (A, B) and to set a load factor (UPA, UPB) of each motor pump (MPU1, MPU2) in order to share a load to generate hydraulic power demanded from the at least one consumer (14) between the first and second motor pumps (MPU1, MPU2), wherein each load factor is set depending from the actual available electrical power (APA, APB).-
