AIR DATA PROBE - UNDER WING MOUNT

OVERVIEW

The AIMMS-20 Air-Data Probe (ADP) measures properties of the airflow in which it is immersed. Temperature and humidity sensors are housed in a proprietary reverse-flow chamber located in the aft section of the probe that results in inertial particle-separation within the flow, which protects the sensors and extends their service life. In addition, an accelerometer triad is incorporated into the module to facilitate direct turbulence measurement.

The ADP acquires the following parameters:

  • Temperature
  • Barometric pressure
  • Relative humidity
  • Pitot-static pressure
  • Angle of attack (flow angle in vertical plane)
  • Sideslip angle (flow angle in horizontal plane)
  • Three-axis acceleration measurement
  • Three-axis magnetic field measurement

Benefits

  • "Smart" sensor probe with integrated sensor analog and digital electronics for high-accuracy, corrected and calibrated output
  • Provides real-time data reduction for true airspeed output
  • Light weight
  • Low power consumption
  • Includes acceleration measurement to assist extraction of turbulence information
  • Two digital interface options for simple integration
    • Controller Area Network (CAN 2.0A)
    • RS-232
  • Available in two different mounting configurations

Options

  • Sting-mount (probe tube only)
  • Anti-icing heaters
  • Different pressure transducer ranges available (1psi for helicopter work, 2 psi for standard fixed-wing and 5 psi for jet aircraft
