Who is this famous Briton? Here is a clue : His occupation was an inventor, an engineer and a scientist. The famous Briton is : SIR BARNES NEVILLE WALLIS (CBE, FRS, RDI, FRAeS). Personal Information. Birthdate:September 26, Birthplace:Ripley, Derbyshire, UK. Married: 23 rd April 1925 to Molly for 54 years until his death. Children: Barnes, Mary, Elisabeth and Christopher. Death:Died October 30, 1979 in Effingham, Surrey, England, United Kingdom aged 92 years. Personal Awards Knighted in 1968 CBE=Commander of the order of the British empire, awarded 2 nd June 1943 FRS=Fellow of the Royal Society in FRAeS=Fellow of the Royal Aeronautical Society. RDI=Royal Designers for Industry Awarded the Albert Medal in Awarded the Royal Medal in 1975 Barnes Wallis was a leader in aviation progress during virtually the whole of his working life. Before World War 1, he was involved in the designing of airships. He was responsible for the R.80, one of the most beautiful airships ever built, and for the R.100, one of the most successful. Barnes Wallis's life was not only based around aeronautics and aerial warfare; he participated in the development of radio telescopy and nuclear submarines, he pioneered work in the de-icing of trawlers, and he gave much time and money to educational advancement and to charity. His Most Famous Achievement The bouncing bomb. After the outbreak of the second world war in Europe in 1939, the engineer saw the need for strategic bombing to stop the enemy being able to carry on. Early in 1942 he began experimenting with skipping marbles over water tanks. His idea was that a bomb could skip over the water surface and sink next to a battleship or a dam wall as a depth charge, with the surrounding water concentrating the force of the explosion on the target. This is a video about Sir Barnes Wallis and his history making invention. A crucial part of his plan was the addition of backspin which meant the bomb trailed behind the dropping aircraft. This stopped the aircraft being damaged by the explosion below and increased the range of the bomb and also prevented it from moving away from the target wall as it sank. The size and weight of the bomb meant that it could only be carried by the Avro Lancaster Bomber. This is what the Bouncing Bomb looked like The bomb had to be dropped at precisely 18 meters above the water and be travelling at 232 miles per hour groundspeed, with backspin of 500 rotations per minute. This meant that the bomb bounced 7 times over 800 yards, sank and detonated causing destructive shockwaves. The bomb was kept in place in the aircraft by a pair of triangulated carrying arms which swung away from either end of the bomb to release it.

Now I will shown you my model On the night of 16/17th May 1943, The Royal Airforce 617 Squadron (The Dambusters) Carried out Operation Chastise an attack on the Mohne, Edersee and Sorpe Dams in Germany. The Mhne and Eder dams were successfully wrecked, causing widespread flooding. This flooding ensured damage to German factories and mines and caused the disruption to hydro- electric power stations. An estimated 1,600 civilians drowned, mainly 1000 were Soviet forced-labourers. Did Sir Barnes Wallis change the World For the Better? YES If the Bouncing Bomb had not been invented Germany would have continued to make weapons which would have been used to kill and hurt people from Great Britain and our allies. The invention of the bomb helped to end WWll. Memorials A public house named The Barnes Wallis exists in Howden Yorkshire. A public house named after Sir Barnes Wallis is located in the town of his birth, Ripley, Derbyshire. The Yorkshire Air Museum at Elvington near York has a permanent display of The Dambusters raid including a replica bouncing bomb and the catapult used to skim stones to test the bouncing bomb theory. A brief history of Wallis' work is also part of the display. A Red Wheel heritage plaque commemorating Wallis's contribution as "Designer of airships, aeroplanes, the 'Bouncing Bomb' and swing-wing aircraft" was erected by the Transport Trust at Wallis birthplace in Ripley, Derbyshire. A Lewisham Council plaque is located at 241 New Cross Road in New Cross, London, where he lived from 1892 to The Student Union Building on the University of Manchester North Campus is named in Walliss honour Wallis was awarded lifetime membership of the Students Union in Nottingham Trent University also has a building named after Wallis on Goldsmith Street. There is a statue to Wallis in Herne Bay, Kent. There is a Barnes Wallis Drive in Byfleet in Surrey. A Barnes Wallis Close in Effingham, Surrey not far from where he lived. Additionally, Barnes Wallis Close in Chickerell, Weymouth, which is within sight of the Fleet Lagoon, where Wallis tested the bouncing bomb. Barnes Road which is off Wallis Street in Bradford, West Yorkshire. There is also a Barnes Wallis Drive in Apley in Telford, Shropshire and also Segensworth in Hampshire. Wallis went on holiday regularly to the Lake District, preferring to stay in the Scafell Hotel, Borrowdale which now has the Barnes Wallis Suite as a featured room. In golf, a Barnes Wallis is a shot that bounces on the surface of a water hazard. Sculpted busts of Wallis are held by Brooklands Museum and the RAF Club at Piccadilly, London.
