The paper presents an innovative hydraulic power generation system able to enhance performance; reliability and survivability of hydraulic systems used in military jet engines; as well as to allow a valuable power saving. This is obtained by a hydraulic power generation system architecture that uses variable pressure; smart control; emergency power source and suitable health management procedures. A key issue is to obtain all these functions while reducing to a minimum the number of additional components with respect to the conventional hydraulic power generation systems. The paper firstly presents the state-of-art of these systems and their critical issues; outlines the alternative solutions; and then describes architecture; characteristics and performance of the hydraulic power generation system that was eventually defined as a result of a research activity aimed at moving beyond the present state-of-art in this field
