CWC-AE Airbus Military A330 MRTT user story

  1. 1. The A330 MRTT is the first tanker transport from Airbus Military with a boom refueling system; this flight test program was critical in the evolution of this technology. Airbus Military conducted more than 350 A330 MRTT flights and nearly 180 more on an A310 demonstrator to obtain the certification. The System 12 Acra KAM-500 DAUs, each acting as an Ethernet node, often physically very far apart The Results • A low risk, re-usable and flexible flight test instrumentation system • Fewer flights due to real-time • Reduction in overall flight test program time through quick, reliable delivery of new products Airbus Military move to an Ethernet flight test instrumentation system for certification A330 MRTT
  2. 2. COMMERCIAL OFF-THE-SHELF MODULAR DESIGN The System The FTI system consisted of 12 Acra KAM-500 DAUs, each acting as an Ethernet node, often physically very far apart. Each DAU contained : • PCM Encoder (used only as unit backplane controller and not as PCM encoder), • Fast Ethernet interface for programming and acquisition • Multiple ARINC-429, MIL-STD-1533 RS-232/422 bus monitors • Various A/D modules. One of the nodes in the data acquisition system was designated as “timemaster node” while the remaining eleven nodes were assumed to be “time-slave nodes”. The time-master synchronizes with the incoming IRIG B time generated by the system time server and broadcasts a proprietary RS-422 synchronization signal to the remaining timeslave nodes providing an accuracy of 1 μsec and 1 PPS synchronization. Acra KAM-500 Lowers Risk Proven on every platform type in all environmental conditions COTS hardware with short delivery times Reduces Cost of Ownership Reduced inventory of spares due to common product line Lower installation, setup and maintenance requirements Modular design greatly extends system lifetime FTI by Design Designed to minimize the data transfer time from sensor to screen Guaranteed predictable data Simultaneous sampling occurs across the complete system
  3. 3. WORKS ONCE WORKS ALWAYS “Working with Acra means hardware is never delayed and support is always at hand. The Results I A low risk, re-usable and flexible flight test instrumentation system This project marked Airbus Military’s first use of a completely networked FTI system. • The success of the hybrid Ethernet FTI system on the A310, meant the system was proven, reliable and mature prior to installation on the A330 MRTT, lowering the risk of the program • The Acra KAM-500 chassis’ modularity yields an exceptionally long useful life with a direct upgrade path to new technologies. Airbus Military has a re-usable Ethernet networked FTI system that can be easily adapted to suit changing requirements and advancements in technology. Pedro Rubio Head of Flight Test Ground Station Group Airbus Military
  4. 4. No other company listens to customers as much as Acra. The Results II Fewer flights due to real-time data access and increased data throughput. The move to Ethernet allowed a dramatic increase in data throughput to handle the increased data acquisition requirements of the program. • Data was available to the FTI engineers in real time and time it took to access the data on the ground was determined only by the time it took to copy the files. • The quantity and quality of data allowed the complex program to be conducted with fewer test flights “ HIGH QUALITY DATA FLIGHT AFTER FLIGHT
  5. 5. UNPARALLELED LEVELS OF CUSTOMER SUPPORT The Results III Reduction in overall flight test program time through quick, reliable delivery of new products When the need for a CAN bus monitor was identified Acra developed the KAD/CBM module in 12 months. During the time it took to develop the new module, Acra provided Airbus Military with a temporary system so that the program could start without delay. The confidence that Acra would deliver a working solution in time was instilled by past success with Airbus, the proven modular architecture of the Acra KAM-500, and a track record of delivering 100+ modules.
