Airspeed calibration tests were conducted on an experimental model of the Elliott low-airspeed system to determine its suitability for use as a helicopter airspeed instrument. The airspeed system was mounted in various locations on the UH-1C helicopter. Emphasis was placed on the low-speed flight regimes where the sensor operated in rotor downwash. The system provides reliable, accurate airspeed data from hover to 120 knots in the direction for which the sensor is mounted, and results indicate an omnidirectional system is feasible.
