V1 and V2 technology: why were these not synthesized for the space program? | |

Rockets carrying their own oxygen supply are really only needed as the atmosphere thins. Anyone see any problems with such a methodology? |

I mean if vertical take-off made sense then every jet would be like a harrier jump jet, but these vectored thrust aircraft are amazingly inefficient, and have little utility except for situations where a runway is unavailable. |

How about showing your calculations ? The launching platform is on rails going downhill gaining velocity, the first stage craft is roughly plane-shaped and launches from the ramp with all its weight in structure and fuel at 200 miles per hour. There is more drag with the shape but there is also lift which is what we want. Engines built to use atmosphere for oxygen will save mass within the vessel which will have to carry less on board. More continuous and numerous multi-staging would also shave mass off the craft as it is using up fuel modules. The calculations would involve a great many factors. It is more of a thought experiment. This goes back to classic sci fi days. Something to think about. Or not. As you wish. |

Even with a boost phase, the V2 was still a small rocket with limited fuel that wouldn't have been able to do anything more than reach the edge of space. |

Quoting: Anonymous Coward 7108100 I thought of a railgun and another way using a balloon to get it 'high enough' then a smaller rocket to finish it off. Use a mountain or volcano for the down slope, then construct a launch ramp. Material science has come along way since the v1 era. Rail gun theory is promising as an added boost in upper stages was what I was thinking. Dirigibles or air ships of some large proportion are also interesting. |

Gravity gets it all in motion, lift gets derived from the air, at higher altitude the wings which also served as booster tanks jettison and a final stage boosts to orbit. Any thoughts on such a concept? Quoting: Anonymous Coward 70729603 Seems much more fuel efficient to my reckoning. The American space program did come out of the German rocket technology, didn't it ? |
