... '''Keywords''' - Launch systems, heavy lift launcher, reusable launch vehicle '''JBIS Reference Code ''' - 2003.56.369 '''Number of Pages''' - 9 Abstract A Reusable Launch Vehicle (RLV) should be sized to minimise the specific launch costs ... the overall acquisition cost. Using a Heavy Lift Vehicle (HLV) with high specific launch costs but able to launch the system in one piece would lead to lower overall acquisition costs. The ...

We launch from Florida. Other nations have different launch sites. The Mojave Desert is a good bet for launch systems initially carried aloft by an aircraft, then launched. Anything that launches vertically will be from ... big difference between launching to orbit and just launching to touch the edge of space and tumble back down. Due to launch frequency to go to the space hotels, the launch areas will have ...

... .53.197 '''Number of Pages''' - 18 Abstract The four-stage Proton-K launch vehicle was first proposed for launching commercial satellites for western customers in the mid-1980s, but because of international politics the first commercial launch did not take place until 1996. This paper reviews the launches of the four-stage Proton-K, concentrating on the various ...

... propulsion. Solid propellants do not require as much fuel- chamber strengthening to withstand a hypervelocity launch as do liquid propellants, but traditional solid fuels have lower exhaust velocities than liquid hydrogen ... . The shock-stability of frozen hydrogen/frozen oxygen propellant has been experimentally demonstrated. A hypervelocity launch system using frozen hydrogen/frozen oxygen propellant would be a revolutionary new development in spaceflight ...
