Automatic Rocket Impact Predictor

The ARIP was designed to improve rocket impact predictions. Previous procedures involved lag time in wind measuring which could not be fully accounted for in an x-time firing decision. This lag time assumes an importance in direct proportion to the magnitude of the wind weighting factors, which with some free flight rockets could be as large as 50 per cent of the total wind effect. Five Aerovane anemometer sensors distributed in the first 100-foot layer provide the data via mechanical and electronic coupling to a computer which has been preset for the ballistic values of a particular rocket. The computer output then activates an X-Y plotter which has been previously zeroed for all other cumulative displacement effects.
