Magnus Data Retrieval Unit – MDRU

General Description

The MDRU II is a hand held computer system designed for retrieval, analysis and display of data acquired by the airborne Engine Monitoring System (EMS) installed in modern jet engines such as F100-PW-220/229, F110-GE-110 and T700-GE-701C. The MDRU II is a generic and versatile device, readily adaptable to handle any modern jet engine.

MDRU Highlights

  • Engine “Go / NoGo” indication for aircraft mechanics on the flight line.
  • In-depth data analysis tool for engine specialists.
  • Increased fleet readiness by reduced turn around time required for EMS data reduction.
  • Real-time monitoring/recording of engine data during ground runs.
  • Flexible communication options to a host computer: RS232, dial-up modem, USB, Ethernet.
  • Report generation and printing.

Construction

The MDRU II is based on the Marvell® PXA270 520MHz CPU, featuring 512MB NAND flash disk, 2 RS232/422 ports, 2 USB ports, 2 Ethernet ports, Wi-Fi, 3.5" QVGA TFT display, 20 functional keys, removable 14.4V 4.8Ah battery pack and an optional SD storage card.
