Dyna-Soar (derived from English dynamic soaring , dynamic gliding flight, pronounced like dinosaur , dinosaur) was a project of the US Air Force (USAF) with the aim of developing a space glider that could be used as a reconnaissance aircraft and bomber as well as for rescue operations , Satellite or space station maintenance or expansion and sabotage of enemy satellites could have been used. The missile, also known as the X-20 , was 10.77 meters long and 6.34 meters wide and was supposed to have a crew of one man. A Titan III was intended as a launch vehicle for orbital flights . The launcher was supposed to transport the spacecraft to a height of 160 km.

history

The project began in 1957 with the merging of previous research, among others at Bell Aircraft Corporation , where Walter Dornberger worked, who had proposed the concept as early as 1952 and it had been pursued under the name BOMI or ROBO (Rocket Bomber). In mid-June 1958, the Air Force announced the contract with Boeing and Lockheed Martin , as well as funding of around $ 150 million for the first prototype. From November 1958, NASA also participated in the development.

The planning of the test flights in 1960 initially provided for high-altitude drops from B-52 bombers. According to this, five unmanned sub-orbital flights should have taken place, followed by eleven manned flights, in which sensors, navigation, but also rendezvous systems would have been tested for the time being, followed by further military systems and a satellite inspection. The program should be carried out in three stages, a rescue glider (Dyna-Soar I), a reconnaissance glider (Dyna-Soar II) and a strategic bomber (Dyna-Soar III). The first gliding flights for Dyna-Soar I should be carried out in 1963, the strategic bomber Dyna-Soar III should be fully functional in 1974.

Until 1961, the Air Force claimed leadership of the American space program. Up until this point in time, however, she moved away from the planned stationing of weapons in 1958, and in 1962 the US Congress spoke of improved cooperation with NASA and the peaceful use of space, for which President Eisenhower had already spoken out in 1958; a use as a bomber had already fallen out of the ranks at that time.

From February 1962 there was a reorientation away from an operational system to an experimental program and the program was officially renamed X-20. The problem of the previously not really defined (military) mission also shifted to a size problem, as the dimensions for supplying a space station seemed very tight. The question arose more and more whether the money was being spent properly. On September 20, 1962, the Air Force's annual report emphasized the cooperation with NASA (as in Project X-15) and the research focus, away from a specifically military potential. In September 1963, novel materials and alloys were tested in a re-entry test.

The project was ended in 1963 after it had cost 660 million US dollars, as all space capacities were to be merged in the lunar landing program or the preparatory Gemini program . The results of the program were incorporated into the space shuttle program in the 1970s . For its part, the US Air Force began work on the Manned Orbiting Laboratory (MOL).

Astronauts

A total of eight astronauts were earmarked for the X-20 project.

Armstrong moved to the NASA astronaut program, crews to the MOL project, and Dana, Knight and Thompson to the X-15 project.
