Time to Think ‘Horizontal’ for Future Space Launches
"Is firing a rocket from the ground straight up
into space the right way to do things? It sure was in the 1950s and ‘60s and it persists today. But it’s still expensive, fraught with technical risk and dwindling into obsolescence. There could be an alternative on the horizon, however, that incorporates the concepts of railguns, scram jets and kinetic launching into an innovative, reusable space launch system for unmanned cargo."

Even though the occasional sled would hit and kill as the primary form of twenty-third century retirement for the underclasses. Trig |

For those too young to remember this TV series, here's a colorized version of the spacecraft taking off from the launch rail and ditching its booster sled: http://www.youtube.com/watch?v=sBZN3c7O9wc The whole concept owes a lot to Sangar's Antipodal Bomber design from WWII.

Time to Think ‘Horizontal’ for Future Space Launches
Reusable boosters are smaller lighter and less costly - according to
Lockheed. http://www.military.com/features/0,15240,220472,00.html VTOVL is the way to go. http://www.scribd.com/doc/30943696/ETDHLRLV to launch significant payloads cheaply. http://www.scribd.com/doc/35439593/S...-Satellite-GEO We start with a small sub-scale version built around RL10 engine parts making up an annular (circular) aerospike engine. This lifts 35 tonnes into LEO. With this capability we build a telecommunications network that earns significant money at the outset. We also use it to test on a small scale, solar power satellite systems. We then build the larger system outlined above, capable of lifting 700 tonnes into LEO. This supports deployment of the 10,000 MW power satellite system described. The smaller vehicle fleet is then used as a test bed for improved performance. Suspending lithium particles coated with frozen methane increases energy density and fuel density. Mixing fluorine with oxygen increases energy and fuel density further. Once the pump and injector and thrust chamber changes are made to operate reliably, along with procedures to minimize adverse effects of exhaust - the smaller system increases to 100 tonnes LEO capability and when applied to the larger system, 2,000 tonnes to LEO are possible. This increases our capabilities - to 30,000 MW at Earth and over 1 TW satellite pairs. We then migrate to laser propelled rocket engines for further improvements. |

But since you're never going to be officially in charge of anything that involves a cent of public loot, or even that of private investors loot, and those you keep sucking up to as right here within these Usenet/newsgroups have no honest intentions of ever doing anything except being as topic/author stalking, naysay and obstructive as possible, means that you're screwed as well as that of humanity simply gets to do without anything Mook. Too bad that you seem to think there are no serial bad guys, no nasty cabals, cartels or special interest conspiracies, and no need of ever revising history in order to reflect the actual truth(s) of what has been holding us back. Instead, you just keep proving to us that the past, present and future are simply as good as it's ever going to get, because William Mook is just another silly flash in the pan that'll never deliver any benefit to humanity unless you manage to outlive most everyone else. "A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it." / Max Planck Good luck with that longevity plan of yours. ~ BG |

My system uses an inflatable thermal protection system to slow below
sonic speeds and fold away wings when gliding below the speed of sound. A tow plane flying down-range snags the booster as it is gliding down-range with a tow line and tows it back to the launch center. There the booster is released. The engine re-starts at a low thrust setting, as the booster climbs into vertical position. It then settles down tail first, like the old tail sitters from the 1950s - on a mobile landing platform. The wings and thermal systems retract and the booster is readied for another launch. |
