Wind speed measuring device for use in helicopter, has radial arm connected with wind energy plant, and with wind-measuring device that is rotated depending on wind direction

摘要

The device has a radial arm (6) connected with a wind energy plant, and with a wind-measuring device that is rotated depending on wind direction. The radial arm is fastened with a housing (3), where rotation of the housing follows in the wind direction, and horizontally extends away from the housing. The radial arm is backwards angled across from a rotational axis of a rotor, and is formed by a tube section that is kept in a position by unbent wires.
