Moog will supply and commission a Test Controller and monitoring system to control the Narec Control Resonance Mass (CRM), which is used to excite natural frequencies in the blade structure and hence evaluate the blades resistance to fatigue under representative dynamic loading conditions. The scope of supply will also include a very high flow PLC controlled Hydraulic Power Unit designed to interface with the Narec primary control system. The power unit, comprising six Moog RKP Radial Piston Pumps, has an installed power of 675 kW, delivering a flow of 1,200 lpm (317 gpm US) at a pressure of 280 bar (4061 psi). A dedicated PLC controls and monitors the performance and health of the unit and a water cooling system maintains the temperature of the hydraulic fluid. High pressure hydraulic fluid is circulated around the facility by a custom designed distribution network.
