Engine Test

UEI hardware is used for:

UEI’s systems are perfect for many types of engine test applications. Whether you are collecting dynamic high-speed data monitoring vibration or lower-speed monitoring of temperature and strain, UEI has your application solution covered. Control your FADEC with ARINC-429 or MIL-STD-1553 to ensure your signals and sensors are valid. When you need to collect your signals accurately, you can rely on UEI!

The United States Air Force (USAF) relies on UEI for rugged hardware for use in the Pacer Comet IV Engine Test Cell. UEI hardware and I/O is used on the following engine testing systems:

• F110
• F101-102
• F108
• F117
• F118-100
• TF33-100

UEI is perfect for all engine tests in any environment

• Rugged Ethernet-based architecture (5G Vibration | 100G Shock | -40 to 85º C | Altitude to 120,000 ft) allows for direct mounting to the test stand or other close to the action environments.
• Reduced noise due to hardware located in proximity with application sensors.
• Wide array of flexible chassis styles that allow for the installation of up to 12 I/O boards.
• Transfer all measurement/control data through a single Ethernet bus.
• UEI distributed systems allow for redundancy and improved safety.
• Hardware can be mounted right on the thrust frame.

All your sensors covered

UEI has boards to collect:

• General purpose signals
• High speed simultaneous signals
• High voltage signals
• Signals requiring channel to channel isolation
• 0-20 mA current readings
• Temperature readings
• Strain gage readings
• Pressure readings
• ICP/IEPE accelerometer readings
• LVDT/RVDT or Synchro/Resolver readings
• Speed from magnetic, hall effect, or optical pickups
• Avionics - 1553, 429, AFDX™
• And more!

UEI’s Importance in Test Cells

The Pacer Comet IV represents a major step forward in Test Cell Design and has set the standard for efficient, high performance jet engine testing. Watch and learn how UEI is played a role in its success.

UEI key benefits included:

• Sending control signals to sensors located in test on and around engine.
• Collecting data from sensors located on and around engine.
• Relaying data to facility monitoring equipment to ensure safety.
• Rapid and efficient testing turnaround times by having UEI directly mounted to interchangeable test frames allowing for “off-line” calibration and configuration.
• High speed communication with no “waterfall” wiring due to the use of an industry-standard Ethernet network that can connect UEI devices mounted on different thrust frames over a single twisted-pair cable.
• UEI's devices proximity to sensors located on engine cell reducing noise and making measurements more accurate.
• UEI's hardware ensuring sensor measurements are “real’ by being able to tell if a sensor is broken.
• “Guardian” readback features enable users to be sure equipment is operating correctly -- sensors are connected, no shorts or open detected, and feedback on control points.
