Rocket propellants boost

World production of perchlorates was less than 1800 tonnes pa until 1940 when wartime missile and rocket requirements boosted this tenfold. World production capacity peaked at around 40000tpa in 1963 but is now still above 30000tpa. More than half of this is converted to NH4CIO4 for use as a propellent ... 

The most advanced among today s projects is the future American reusable launch system known as Venture Star. It utilizes two new concepts that are expected to boost efficiency and cut down the cost of a payload. The first is the single stage-to-orbit concept—the launch vehicle carries the entire propellant load and does not have any expendable parts. The latter is planned to be achieved by a revolutionary rocket engine design called Aerospike. The bell-shaped noz-... 

Another consideration in the design of a rocket motor is the boost velocity, or velocity which the vehicle will attain when all the propellant has been consumed. Neglecting drag losses, this velocity becomes...
