A novel pump design for an efficient and compact Electro-Hydraulic Actuator IEEE aerospace conference

This paper presents an innovative design solution for a compact Electro-Hydraulic Actuator (EHA). Although the current trend in many mobile applications is towards Electro Mechanical Solutions (EMAS) instead of Hydraulic Actuation systems (HAS), the use of HEAs could represent the best technological compromise. In fact, EHA can combine the power to weight ratio advantage of hydraulic technology with the versatility and ease of control of electric technology. Compared to EMAS, which are often equipped with low efficiency load holding mechanisms, EHAs can also offer superior energy efficiency.
