Lawrence Hargrave - Career, Honors and memorials

sydney engine aircraft five

Aeronautical pioneer, born in Greenwich, EC Greater London, UK. He arrived in Sydney in 1865, and spent five years exploring in New Guinea before being appointed to a post at the Sydney Observatory (1878). He resigned five years later to devote his time to aeronautical experiments. In 1893 he developed the box-kite to produce a wing form used in early aircraft, and in 1894 four tethered kites successfully lifted him 5 m from the ground. He also designed a radial rotary engine in 1899, the predecessor of the engine which drove most aircraft in the early days of aviation. His other projects included wave-driven ships and a one-wheel gyroscopic car.
