title = "A novel electrical servo variable displacement hydraulic pump used for integrated actuator in MEA",
abstract = "The More Electric Aircrafts(MEAs) such as A380 and B787 apply the Electro-Hydrostatic Actuator (EHA)/ Electro-Mechanical Actuator (EMA)/ Electrical Back-up Hydrostatic Actuator (EBHA) to drive the flight control actuations surfaces.Now the PBW actuators have been widely applied into more control surfaces. Such kinds of actuators have shown very good advantages. Next generation aircrafts will use more EHA and EMA. EHA requires the servo motor and servo pump for high performances. Among many kinds of EHAs, the EHA-Variable-displacement Pump(VP) is of its better characteristics. In this paper, an electrical servo variable pump is developed for EHA, and the adapted electrical variable servo mechanism is designed. Simulation and analysis show that this kind of servo pump is of very good performances that suited for Power-By- Wire(PBW)actuators. In the end, the experiment results are given and compared with theoretical one. It is indicated that this electrical servo variable pump has a good prospect of application.",
