Sir Barnes Neville Wallis CBE FRS RDI FRAeS [3] (26 September 1887 – 30 October 1979) was an English engineer and inventor.He is best known for inventing the bouncing bomb used by the Royal Air Force in Operation Chastise (the "Dambusters" raid) to attack the dams of the Ruhr Valley during World War II.
The inventor of the first such bomb was the British engineer Barnes Wallis, whose "Upkeep" bouncing bomb was used in the RAF's Operation Chastise of May 1943 to bounce into German dams and explode underwater, with an effect similar to the underground detonation of the later Grand Slam and Tallboy earthquake bombs, both of which he also invented.
Operation Chastise, commonly known as the Dambusters Raid, [1] [2] was an attack on German dams carried out on the night of 16/17 May 1943 by 617 Squadron RAF Bomber Command, later called the Dam Busters, using special "bouncing bombs" developed by Barnes Wallis.
In Spring 1942, aeronautical engineer Barnes Wallis is struggling to develop a means of attacking Germany's dams in the hope of crippling German heavy industry.Working for the Ministry of Aircraft Production, as well as his own job at Vickers, he works feverishly to make practical his theory of a bouncing bomb which would skip over the water to avoid protective torpedo nets.
The site was used to develop a more effective air-raid shelter, built over five and a half months at a cost of £250,000.Once complete, the site became the first to be subjected to the devastating effect of Barnes Wallis's Grand Slam bomb, which was test-dropped on the site.
Tallboy or Bomb, Medium Capacity, 12,000 lb was an earthquake bomb developed by the British aeronautical engineer Barnes Wallis and used by the Royal Air Force (RAF) during the Second World War. [a] At 5 long tons (5.1 t), it could be carried only by a modified model of the Avro Lancaster heavy bomber. It proved to be effective against large ...
Vickers staff from Weybridge were dispersed to this area and facilities for developing the bouncing bomb were based nearby in Foxwarren Park. In 1942, Barnes Wallis and his secretary, rowing champion Amy Gentry, rowed out onto the lake where Wallis fired differently-shaped models from a catapult and Gentry then rowed to retrieve them.
The devices, developed by British war-time "Dambuster" engineer Barnes Wallis, are similar to the bombs used to destroy German dams during the war. Divers retrieve World War Two 'bouncing bombs ...
