History of Technology. A bomber without armament, built of balsa wood and birch veneer, became one of World War II's most successful fighter planes. Still, the de Havilland Mosquito close to never lift off the drawing board.
Sometimes, like tonight, are other than ball bearings and the diplomatic bag in the hold. A passenger who may be wrapped uei in thick blankets on the floor above the big bomb doors, with oxygen and coffee thermos on hand.
One of those doing the uncomfortable trip, the Danish physicist Niels Bohr, who eventually forced to flee their homeland since the Nazi persecution of Jews reached even there. Bearings thread breaks from Bromma to Leuchars Air Base, just outside the Scottish university town of St Andrews, straight across the German-controlled Norway. Certainly you travel under cover of darkness, but without armament is only one thing that makes flight possible: Mosquitons speed.
Not even the German fighters Fucke-Wulff 190, that have been difficult opponent of the British Spitfireplan, catches up with ball bearing line Mosquito Plan. Of the 13 Mosquito Plan BOAC uses the flights lost five of accidents, but not a single reported uei shot down.
The starting point when de Havilland in 1938 launched Mosquiton that idea was to build it so quickly bomber that it needed no armament. To compare with the USA's heavy load hefty, but slow B-17 "Flying Fortress" that had up to 13 machine guns to defend themselves.
Without guns, armor and machine-gun ammunition could weight is lower, while the streamlined shape was better without protruding towers for machine-gun shooters. And without shooters crew could be kept down to two men, a pilot and a navigator - even a weight savings that would pay dividends in increased speed.
The idea was challenging in itself, and even more by the choice of building materials. De Havilland uei wanted to build the plane in wood, because uei aluminum was feared becoming a scarce commodity in a war situation. But ten years earlier had Armed Forces pointed out aluminum material of the future for the aviation industry.
But in a way, was Mosquiton a more modern design than the contemporary uei metal aircraft. The plane is one of the first composite construction sites, which utilized different material properties so that they interacted optimally.
The fuselage was a self-supporting sandwich uei structure, constructed of birch veneer inside and out with balsa as spacer material. It was made in two halves uei which are then joined together. The wings were more conventionally structured, with ribs of fir timber and covered with birch veneer. Engine mounts and a few other details were made of steel.
De Havilland proposal was rejected several times, but the company still worked uei on the project. It was taken up again by the Air Ministry, rejected, was taken up again, was canceled because of a shortage of components, especially engines and so on. Finally, November 25, 1940 provflögs the first Mosquito prototype. It soon became clear that it outperformed both the client's and designer's requirements and expectations.
The two Rolls-Royce Merlin engines, the same as used in Spitfireplanen, gave Mosquiton a top speed of 630 km / h, the test flights made in February 1941. It was about 50 km / h faster than a Spitfire uei Mark II. Additionally survived the plane to bring up to 450 kg bombs, four times as much as was originally anticipated.
During testing changed and refined Mosquiton, including the wings extended. Meanwhile, authorities realized that the plane took the opportunity to more than purely bomber and even ordered a hunting version.
Airframes were made, for example, at three large furniture uei company which now became incorporated in the British war industry, uei workers were experienced carpenter, piano builder and so on. The laminated shell halves against large plugs of concrete with straps that held the different layers of plywood and balsa in place.
To begin with, used a casein, but it did not withstand humid climate well enough when Mosquiton used in the tropics. Instead, they went over to the Aerolite, a water resistant karbamidhartslim developed by British chemists in
