 Horatio Phillips is best known for his patented "double surface aerofoil" sections. His results and designs were republished by Chanute and almost certainly influenced the Wright Brother’s understanding of their own wind tunnel data.
Phillips built a wind tunnel using steam injection to create the airflow. In 1884 he patented a series of curved aerofoils designed “… in such a way as to as to cause a partial vacuum to be created over a portion of the upper surface of the blade thus aiding the air below to support the weight.”
Phillips' steam powered models and man carrying planes have been described as "flying Venetian blinds" and even as a "flying runner bean frame." His 1904 plane made only a brief hop, but the1907 construction made a flight of 500 feet at Steatham, the first powered hop in England.
