The Norden Bombsight and the U.S. Naval Proving Ground
A bombsight is a device used by military aircraft to drop bombs accurately. Bombsights, a feature of combat aircraft since World War I, were first found on purpose-designed bomber aircraft and then moved to fighter-bombers and modern tactical aircraft as those aircraft took up the brunt of the bombing … See more Forces on a bomb The drag on a bomb for a given air density and angle of attack is proportional to the relative air speed squared. If the vertical component of the velocity is denoted by See more Calculating the effects of an arbitrary wind on the path of an aircraft was already a well-understood problem in air navigation, one requiring basic vector mathematics. Wimperis was very … See more In the pre-World War II era there had been a long debate about the relative merits of daylight versus night-time bombing. At night the bomber is virtually invulnerable (until the … See more The strategic bombing role was following an evolution over time to ever-higher, ever-faster, ever-longer-ranged missions with ever-more-powerful weapons. Although the tachometric bombsights provided most of the features needed for accurate bombing, … See more All of the calculations needed to predict the path of a bomb can be carried out by hand, with the aid of calculated tables of the bomb ballistics. However, the time to carry out these calculations is not trivial. Using visual sighting, the range at which the target is first … See more One of the main problems using vector bombsights was the long straight run needed before dropping the bombs. This was needed so the pilot would have enough time to accurately account for the effects of wind, and get the proper flight angle set up with … See more During the Cold War the weapon of choice was a nuclear one, and accuracy needs were limited. Development of tactical bombing systems, … See more WebAlong with Elmer Sperry, Norden worked on the first gyrostabilizers for United States ships, and became recognized for his contributions to military hardware. In 1913, he left Sperry to form his own company. In 1920, he began work on the Norden bombsight for the United States Navy.

The Biggest Lie of WWII? The Myth of the Norden Bombsight
WebBombsights are sighting devices that are pointed in a particular direction, or aimed. Although the solution outlined above returns a point in space, simple trigonometry can be used to convert this point into an angle relative to the ground. The … WebOn 3rd November 1943, just a week before her 24th birthday, Dorothy was working at the airfield at Holme on Spalding Moor in the East Riding of Yorkshire, fitting and testing a … WebOn December 2, 1941, the acting chief of the Bureau of Aeronautics enthusiastically wrote to the secretary of the Navy, “The Norden bombsight is considered to be the principal single factor of superiority which the air forces of this country possess over those of potential enemy countries.” function of behavior focus tangible
