ABSTRACT:
The invention relates generally to measuring the air speed of an object moving within the earth's atmosphere. In particular, the invention provides apparatus which comprises means for causing an air flow to enter an electric E field chamber, proportional to air speed, a portion of the air in the air flow being ionized prior to entry into the E field. Air speed is measured by the current resulting from charge separation in the field.
