Horatio Frederick Phillips (born 1845 in Streatham〔(【引用サイトリンク】title=Horatio Phillips )〕 – 1924) was an early aviation pioneer from the United Kingdom. He was famous for building ''multiplane'' flying machines with many more sets of lifting surfaces than would be normal on modern aircraft. However he made a more lasting contribution to aeronautics in his work on aerofoil design.〔Wragg, D.W.; ''Flight before flying'', Osprey, 1974〕 ==Aerofoils== Phillips devised a wind tunnel in which he studied a wide variety of aerofoil shapes for use in providing lift. The tunnel was unusual in that the gas flow was provided by steam rather than air.〔 By 1884 he was able to register his first patent, and more were to follow. He demonstrated the truth of George Cayley's idea that giving the upper surface greater curvature than the lower accelerates the upper airflow, reducing pressure above the wing and so creating lift.
