Atlas rocket

FI ox. Fluorine/Oxygen Mixture for Atlas Rockets. A research program of the Lewis Research Center of NASA using this new propellant indicates that the pay load capacity is increased by 90% for 160km high orbits and by 65% for tasks with escape velocity. About 30% fluorine 70% oxygen is taken as a basic mixt... 

Out of the bipropellant mixtures shown in Table 2.7, only a few are used in practial applications. In particular, L0X/H2 has proven useful in the cryogenic main engines of the civil Space Shuttle and Ariane V. The Aestus upper stage of the Ariane V relies on using NTO/MMH. The engines of the Delta (RS-27) and Atlas rockets...

The special needs of the space program motivated the search for composite materials for other reasons also. For example, during tests of the first Atlas ICBM (intercontinental ballistic missile), engineers were concerned that the rocket s metallic components would not survive the missile s reentry into the atmosphere they feared it would melt down because of the intense heat to which it was exposed. By the late 1950s, therefore, aerospace researchers had begun to look for satisfactory substitutes for metal alloys for such applications. With that research, the modern held of composite design was horn. One of the first composites tested consisted of pieces of glass embedded in melamine, purported to be the first composite material developed for aerospace applications. 

WD-40 is a proprietary formula composed of aliphatic petroleum distillates, petroleum base oil, carbon dioxide, and other nonhazardous ingredients. In 1953, the Rocket Chemical Company set out to create a line of rust prevention solvents and degreasers for use in the aerospace industry. On the fortieth attempt, they succeeded in formulating an effective water-displacing/lubricating formula, which they called WD-40. This product worked so well that it was used to protect the outer skin of the Atlas Missile from oxidation. It worked so well that employees of Rocket Chemical would sneak out cans of the formula for use in their own homes. The company produced a consumer version of the product in 1958, and since then people have used WD-40 on virtually everything.

Using the larger experimental value of g(/,a), this equation shows that a facility designed to test an electric rocket with only 0.01 lb thrust required about 336 ft of condenser area. For flight applications we are interested in thrust values equal to about 10" times the initial vehicle weight, or about 1 lb of thrust for vehicles launched by the Atlas-Centaur booster. A facility to test such a thrust unit would require about 34,000 ft of condenser surface area. 

The Atlas-Centaur was the first rocket to use liquid hydrogen as a fuel. The first stage used the well-developed Atlas, described above, and liquid helium was used to precool the RL-10 engines of the Centaur. The Atlas-Centaur was specifically developed to soft land scientific instruments on the moon in preparation for the Apollo landings, and the 907-kg Surveyor successfully launched by the Atlas-Centaur landed on the moon in July 1964.
