The Battle of the Beams: The secret science of radar that turned the tide of the Second World War

And so by the foresight and decision of one man, Professor R V Jones, in November 1940, the Wolverhampton area escaped the horror of a massive "Coventry-like" air raid.

But at this point it was just a theory. Jones’s masters were unimpressed. The RAF insisted, in the face of their own experience, that such navigational aids were unnecessary for bombing. He needed more clues. Mysterious coordinates Evaluate a solution to a complex real-world problem, based on scientific knowledge, student-generated sources of evidence, prioritized criteria, and tradeoff considerations.X-Gerät was used effectively in a series of raids known to the Germans as "Moonlight Sonata", against Coventry, Wolverhampton and Birmingham. In the raid on Birmingham only KGr 100 was used, and British post-raid analysis showed that the vast majority of the bombs dropped were placed within 100 yards (91 m) of the midline of the 'Weser' beam, spread along it for a few hundred yards. This was the sort of accuracy that even daytime bombing could rarely achieve. A similar raid on Coventry with full support from other units dropping on their flares almost destroyed the city centre. [20] Countermeasure [ ] As I was reading this book, a succession of seemingly far-fetched associations and recollections were projected - or perhaps should I say 'beamed' - onto my mind. FIRST, THOUGH, the Vikings of KGr 100 would have their moment to shine. On the evening of November 14, its crews clambered into their Heinkels. The night was so clear that the observers could easily see the countryside below by the moonlight. Just after

In the early part of the Second World War the Germans began to use a radio beam system which they had been developing since the mid thirties. It was a guidance system, which used intersecting radio beams to direct aircraft to any particular target in Britain. Once students have read the instructions, direct each group to select reinforcement type and processing temperature range. Begin preparing the matrix resin. Brown, Louis (1999).

As a class, discuss and compare results, as described in the Assessment sectino. Ask students how they would improve their beam designs if they had time to make new ones. The group with the highest fracture stress wins the competition. (optional) Hand out a first place team prize for ingenuity, closest prediction for weight before breaking, and any additional prizes to other groups—at the teacher's discretion.

However, shortly afterwards he had an enthusiastic telephone call from Squadron Leader Felkin, who said that a conversation between two German prisoners had been overheard. They said that the raid on Coventry had been very successful and so had the raid on Birmingham. The Lorenz beam and its two lobes. Note that the "equisignal" area in the centre grows narrower, and more accurate, as the aircraft approaches the runway Some sections, such as diagrams and indexes, were missing but these would have been added prior to publication. An account of real-life WWII technology is as engaging as a thriller and provides a 'howdunit' rather than a 'whodunit'. Excellent. Engineering and Technology

Such misunderstandings, whether in science or intelligence, are usually bad news. This time, however, they would help Jones to a breakthrough. He concluded that the X-Device was somewhere on the German planes but disguised as something else. He loved puzzles and challenges, and now the Luftwaffe had provided him one. collecting clues X-Gerät was used effectively in a series of raids known to the Germans as Moonlight Sonata, against Coventry, Wolverhampton and Birmingham.

Radio beacons were already used for airplane navigation. Because the beacon’s locations were known, an airplane’s navigator could take a bearing on them to determine the plane’s position. Plendl had a different idea, and when Germany invaded Poland, some of its bombers were carrying the X-Device he had designed. analyze and evaluate scientific explanations by using empirical evidence, logical reasoning, and experimental and observational testing; The masterly crafted plot of this 'documentary thriller' is such that retelling it here would be a certain spoiler. Yet, I cannot refrain from revealing a totally unexpected (for me at least) final twist from the book's short postscript, in which the author introduces us to another real-life character – Admiralty scientist Raymond Whipple. Yes, the author's namesake. More than that: his own grandfather, who met his wife, Mary, the author's beloved 'Granny Mary', while researching radio waves.Investigating or designing new systems or structures requires a detailed examination of the properties of different materials, the structures of different components, and connections of components to reveal its function and/or solve a problem.
