Development of The Test Article
The Saturn V consisted of three stages and an Instrument Unit (IU). The first stage, S-IC, delivered 7,610,000 pounds-force (33.9 MN) thrust and delivered the other stages to 200,000 feet (61 km). Afterwards, it was jettisoned to fall into the Atlantic Ocean and the second stage continued acceleration. The second stage, S-II, was responsible for lifting the remaining parts nearly to Earth orbit. The third stage, S-IVB provided the final push to orbit and the trans-lunar injection burn to set the Apollo spacecraft on a course to the Moon. The IU was the guidance and control computer. SA-500D was the assembly of these components for dynamic testing.
The Saturn V Dynamic Test Stand with "electrodynamic shakers" provided a table capable not only of holding the Saturn V fully assembled and fueled, but also able to simulate the vibrations that would be generated by rocket engines.
The components used for testing were developed from 1964–66, and the tests conducted in 1966-67. Because the Saturn V shared some components with the Saturn IB, some of the components for SA-500D were initially used for dynamic testing with the Saturn IB stack.
In naming the individual stages, MSFC used the stage designation with a suffix indicating its purpose. For example, S-IC-D was the first stage, S-IC, for dynamic testing, and S-IC-1 was the first flight model of the first stage. Suffixes used were S, for structural, F for facilities, T for all-systems test, and D for dynamic testing.
Following is a history of each component of the dynamic test article in order of appearance.

Famous quotes containing the words development of, development, test and/or article:
“Fascism, the more it considers and observes the future and the development of humanity, quite apart from political considerations of the moment, believes neither in the possibility nor the utility of perpetual peace.”
—Benito Mussolini (18831945)
“Ultimately, it is the receiving of the child and hearing what he or she has to say that develops the childs mind and personhood.... Parents who enter into a dialogue with their children, who draw out and respect their opinions, are more likely to have children whose intellectual and ethical development proceeds rapidly and surely.”
—Mary Field Belenky (20th century)
“[17th-century] Puritans were the first modern parents. Like many of us, they looked on their treatment of children as a test of their own self-control. Their goal was not to simply to ensure the childs duty to the family, but to help him or her make personal, individual commitments. They were the first authors to state that children must obey God rather than parents, in case of a clear conflict.”
—C. John Sommerville (20th century)
“Natures law says that the strong must prevent the weak from living, but only in a newspaper article or textbook can this be packaged into a comprehensible thought. In the soup of everyday life, in the mixture of minutia from which human relations are woven, it is not a law. It is a logical incongruity when both strong and weak fall victim to their mutual relations, unconsciously subservient to some unknown guiding power that stands outside of life, irrelevant to man.”
—Anton Pavlovich Chekhov (18601904)
