Design and validation of hydraulic pump system driven by the electromotor under the high-power and long-time working state in an airborne

This paper introduced a type of aircraft electric hydraulic pump system working principle, the key points of the system are analyzed and described, including calculation of boost pressure, system oil temperature control design, environmental temperature checking, starting logic design, the system validation and verification methods are expounded. This system passed through the ground test and flight time Validation, and worked well and reliably.
