Hovercrafts
In 1959 Sir Christopher Sydney Cockerell
was an English engineer, best known as ‘the inventor of hovercraft’. A cushion
of air supporting the craft just about the ground of water. Vertical fans
propel the craft. Most a re powered by gas turbine or diesel engines.
Hovercrafts travel at speeds up to 160km per hour. They are used a marine
ferries and as military vehicles.
Cockerell built several models of his
hovercraft design in the 1950’s, featuring an engine mounted to blow from the
front of the craft into space below it. He demonstrated the model flying over
many Whitehall carpets.
