SIR CHRISTOPHER SYDNEY COCKERELL
Sir Christopher Sydney Cockerell was born in Cambridge,1910. He educated at Gresham's School and then he entered Cambridge Univercity. After he had studied engineering he began to work for Marconi Company. He work there on radar systems.
During the war years, Christopher Cockerell worked with an elite team at Marconi to develop radar, a development which Churchill believed had a significant effect on the outcome of the Second World War, and Cockerell believed to be one of his greatest achievements. While at Marconi, Christopher Cockerell patented 36 of his ideas. Christopher Cockerell was knighted for his achievement in 1969.
HOVERCRAFT
Hovercraft was invented by Christopher Cockerell in 1959. Cockerell desinged a long flexible skirted boat. The air which was absorbed by giant fans on the deck was pomping under the boat with the narrow jets around the perimeter of the boat.
This meant that the cushion of high pressure air could be maintained by a very much smaller engine; and for the first time, a craft could be lifted completely out of the water.To test his hypothesis, he put one a smaller can inside a larger can and used a hairdryer to blow air into them. The downward thrust produced was greater when one can was inside the other rather than air just being blown into one can.
In 1968, the voyage broke out between England and France.
