Horatio Frederick Phillips

Horatio Frederick Phillips (1845[1] – 1924) was an English aviation pioneer, born in Streatham, Surrey.

He was famous for building multiplane flying machines with many more sets of lifting surfaces than are normal on modern aircraft.

[2] Phillips devised a wind tunnel in which he studied a wide variety of aerofoil shapes for use in providing lift.

Phillips believed that multiple stacked wing planes (or "sustainers" as he called them), in "Venetian blind" configuration, offered advantages.

Though successful, the 1907 model showed poor performance compared to more conventional contemporary types.
