I always wondered: would a 10,000 lb, 40 feet small rocket with retractable delta wings winched from a cargo plane,propelled by a jet similar to a f22 to mach 3 before igniting its own rocket My question: is how much fuel would i need to get to space?

    $\begingroup$ Why bother to retract the wings? Also how many airplanes are involved here, both a cargo plane and an f-22? More details please. $\endgroup$ – Organic Marble Dec 27 '17 at 15:12

    $\begingroup$ @OrganicMarble I'm going to wait for the movie; though not yet sure if it's going to be a Daniel Craig or an Austin Powers. $\endgroup$ – uhoh Dec 28 '17 at 10:21
  • $\begingroup$ AIU, he's proposing the rocket have a first stage that uses a jet engine (e.g. the F-119 engine as used on the F-22) instead of a rocket engine. $\endgroup$ – Hobbes Dec 28 '17 at 11:49
  • $\begingroup$ I was planning not to stay in space i figured a pair of wings could be deployed after the high heat in re entry and glide home $\endgroup$ – C Daless Dec 29 '17 at 13:21

    $\begingroup$ I think you could start to use the "," character. It is used to separate clauses. You have a 4 line long sentence without a single ",". Nobody likes to decode it. $\endgroup$ – peterh - Reinstate Monica Dec 29 '17 at 17:13

Your proposed design isn't too much different from the Pegasus rocket, although Pegasus is quite a bit heavier (18,500 kg=40,785 lb), the wing isn't retractable, and Pegasus doesn't use an initial jet engine.

    $\begingroup$ Technically, Pegasus uses 3 jet engines in its first stage. en.wikipedia.org/wiki/Stargazer_(aircraft) $\endgroup$ – Russell Borogove Dec 27 '17 at 15:03
  • $\begingroup$ but that would be the "Cargo plane" in the question, @RussellBorogove $\endgroup$ – JCRM Dec 27 '17 at 22:35
  • $\begingroup$ Thank You Eugene, tjhe 10,000 lb would not include the rocket fuel i have no idea how much fuel it would need $\endgroup$ – C Daless Dec 29 '17 at 14:27
  • $\begingroup$ Thank You Eugene, tjhe 10,000 lb would not include the rocket fuel i have no idea how much fuel it would need, the Cargo plane would be required to bring the small rocket to 40.000 feet not sure if a mach 3 capable plane could take off with a 10000 lb load plus fuel $\endgroup$ – C Daless Dec 29 '17 at 14:36
