The Bell X-1 is an American experimental and rocket plane, which were designed by Theodore of The single-seat midwing monoplane had been particularly developed for it the sound barrier to break through. The machine was thrown off in air a nut/mother airplane (Boeing a B-29 or a B-50) and continued then with its own engine the flight. The machine possessed ungepfeilte bearing areas and a Kreuz-Leitwerk. The chassis was retractable. The form of the fuselage resembled the one increased rifle bullet. The engine technology was an advancement of the German rocket technology of the Second World War. The fuel, alcohol and oxygen, were promoted thereby through under high pressure standing nitrogen to the combustion chambers. The first flight, still without drive, took place on 19 January 1946. Already in December the first flights with engine could be accomplished. On 14 October 1947 then Captain Charles E succeeded. to Yeager first manned supersonic flight. The machine reached a speed of Mach 1.015 in approximately 12,800 m flight altitude. 3 machines were manufactured by the output type of the X-1. While the first machine was used by the American Air Force went the 2. Machine to the NACA, the predecessor of NASA. The third machine was destroyed at the soil, after it could accomplish only one gliding flight.

The Bell X-1A resembled the X-1, had a new cockpit hood and a longer trunk for the admission a larger amount of fuel. New was also the fuel system, which worked now with turbopumps. Also this machine was used by the American Air Force for research purposes. On 12 December 1953 thereby the speed of Mach 2.435 could be obtained. The largest obtained height was with 27.400 M. the machine went in September 1954 because of the NACA, which wanted to use it for further tests. However the machine already fell with 2. Test flight on 8 August 1955 off and was destroyed.

The Bell X-1B essentially corresponded to that Bell X-1A, had however a changed wing. Also this machine was used first by the American Air Force for high-speed test flights and handed over then in January 1955 the NACA. This used the machine to at the beginning of of 1958 for its research program.

It gave a project for to Bell a X-1C, which was not implemented however. The Bell X-1D had to be emergency-thrown off in August 1951 its nut/mother airplane, Boeing a B-50, and still exploded in air.

The last execution, the Bell X-1E, was the second original Bell X-1, which was supplied to the NACA. At this machine new wings were installed, the fuel system on the later conditions was brought with the turbopumps and the windshield was changed. The first flight took place on 12 December 1955. The flight tests continued to end of the yearly 1958, then also this X-1 was superseded.

For the OSCAR nominated the US film "the material, from that the heroes are" (1983) told among other things also the history of the American test flight program. In the year 1984 the piece of "The Great X-1" appeared the Australian Electro Wave volume Informatics, with which the X-1 a further (although small) popular-cultural monument was set.
