Description

The new-generation aircraft uses pneumatic power controls combined with electric power for environmental control, ice protection, and APU units. The hydraulic units were with a de- centralized hydraulic control. These are backup flight controls with mini-pumps driving electro-hydraulic actuators (EHA). Smaller than conventional pumps, these mini-pumps can be installed near the actuators. They operate at very high pressure (5,000 psi) and speed, delivering impressive performance for their sizes.
