Boeing mock-up of X-20 Dyna-Soar. Days after the launch of Sputnik 1 on 4 October 1957, on either October 10 [18] or October 24, [19] the USAF Air Research and Development Command (ARDC) consolidated Hywards, Brass Bell, and Robo studies into the Dyna-Soar project, or Weapons System 464L, with a three-step abbreviated development plan.
Professor Walter Gregorii had Sänger rework his report, and a greatly reduced version was submitted to the RLM in September 1944, as UM 3538. It was the first serious proposal for a vehicle which could carry a pilot and payload to the lower edge of space.
The Lockheed Star Clipper was a proposed Earth-to-orbit spaceplane based on a large lifting body spacecraft and a wrap-around drop tank.Originally proposed during a United States Air Force program in 1966, the basic Star Clipper concept lived on during the early years of the NASA Space Shuttle program, and as that project evolved, in a variety of new versions like the LS-200.
Three of the flights had flown above the Kármán line (edge of space), and one was intended to do so. In each of these accidents the entire crew was killed. As of December 2023, a total of 676 people have flown into space and 19 of them have died. This sets the current statistical fatality rate at 2.8 percent.
Dornberger and Ehricke also collaborated on a 1955 Popular Science article pitching the idea for airliner use. [ 13 ] [ 14 ] The introduction of successful intercontinental ballistic missiles (ICBMs) in the offensive role ended any interest in the skip-glide bomber concepts, as did the reconnaissance satellite for the spyplane roles.
It was designed in 1933 by Wernher von Braun at the German Army research program at Kummersdorf headed by Colonel Dr Walter Dornberger. The A1 was the grandfather of most modern rockets. The rocket was 1.4 metres (4 ft 7 in) long, 30.5 centimetres (12 in) in diameter, and had a takeoff weight of 150 kilograms (330 lb).
The missile was to have a range of 100 miles (160 km), [1] [11] [12] Bell's development effort was led by Walter R. Dornberger. [13] Rascal, was required to carry a 5,000 pound warhead a distance of 150 nautical miles at a speed of Mach 3.0 by July 1955.
