WIND TUNNEL AND FLIGHT EVALUATION ROSEMOUNT SHIELDED PITOT-STATIC TUBE MODEL 850N.

Abstract

Test airspeed probes are generally of a fixed or swiveling pitot-static type. Fixed probes are inaccurate at the low speeds and large inflow angles common to helicopter flight regimes. Swivel head probes provide more accurate information, but are often limited by the dynamic pressure they can withstand. A fixed probe which was reportedly not sensitive to angles of attack or sideslip was tested in the wind tunnel and on a helicopter to evaluate suitability for use as a test instrument. (Author)
