Hydraulic System |
Facility to generate 280 bar, 110 lpm hydraulic power using either aircraft standard LRUs or commercial pumps Aircraft standard LRUs like pumps, accumulators, isolation valves, reservoirs, etc., interfaced with the plumbing geometrically identical to that on aircraft Automatic switchover to 260 bar, 30 lmp backup pump on detecting failure of 280 bar, 110 lmp main pumps Automatic switchover to battery driven 210 bar, 11.5 lpm ultimate backup pump Thyrister controlled variable speed prime mover to drive aircraft pumps - Microprocessor based Digital Hydraulic Electronic Unit (DHEU) to facilitate in
operation and health monitoring of overall hydraulic system as on aircraft
|
Electrical System |
Facility to generate DFCC electrical power supply either using aircraft standard LRUs or commercial power supply units Facility to simulate power-on sequence and relative power-on delays among all four channels encountered during startup using ground power supply Facility to simulate power interruptions during changeover from ground power to aircraft power supply Automatic switchover from HMDG to battery backup power supply on detecting hydraulic system failure
|
