Reusable Atlas
A concept that Convair/GD pushed for a while in the 1960's was a
flyback version of the Atlas. The core would be structurally strengthened, the booster engines would be permanently afixed, wings, landing gear, jet engines and a cockpit would be added. Additionally, the Centaur would be repackaged as the propulsion system for a lifting body "space shuttle." End result would be a fully reusable space launcher based in part on existing hardware. I have a GD/Convair report on this concept availabel he: http://www.up-ship.com/drawndoc/drawndocsale.htm |

The booster kinda has a "brontosaurus" look, but the spaceplane is
kinda cute and cuddly. /dps |

It's going to take a lot of "reinforcement" to make that booster capable of taking the heat it's going to encounter as it returns to the surface after the spaceplane separates. "Winged Titan" was fairly impressive looking also: http://www.astronautix.com/lvs/wintitan.htm Pat |

(There's another one on the page, the Martin Midget attack plane, that looks like a jet version of the WW2 BV-40 glider fighter.) Mike |

And another appearance comment: the booster looks like someone at Convair had a special relationship with the nose of the B-36. The similarity is remarkable. One wonders why whoever it was didn't go with the pointed YB-60 nose, which had the same bubble canopy. Mike |

Assuming you don't stall out while gliding in for landing on the runway, the poor aerodynamics might be an advantage in bleeding off speed during reentry and landing approach, so you could avoid the speed loss banking of the Shuttle on the way down. The X-24B/FDL-7 design was the flip side of that concept; it had remarkably low hypersonic drag during reentry, and a spectacular cross-range capability once it was in the upper atmosphere. (See the drag/cross-range graph in "The Hypersonic Revolution") Landing speed would have been a lot higher than the Shuttle for a FDL-7/8 based shuttle orbiter-sized vehicle, but its layout would have given it great internal volume for its size and overall weight.
