Arrow Queen interplanetary VTOL SSTO

(Breaking Ground required)

The Arrow Queen is the heavier sister of the Arrowmaker, and with nuclear engines and a lot of fuel, can get up to 2020m/s delta-V in orbit. This is enough to land on Mun (with a suicide burn, but margins are maximum 100m/s), Minmus or Duna (no parachutes needed, after aerobrake just retrograde burn with nuclear engines) before refuelling and continuing into the rest of the universe.

Details

  • Type: SPH
  • Class: spaceplane
  • Part Count: 118
  • Pure Stock
  • KSP: 1.9.1

Getting into orbit is a lot more difficult than with the Arrowmaker, as above 30km all the propulsion comes from nuclear thrust. Here’s what I do:

Guide:

  • Press 1 to activate hover engines, then press 2 to activate RAPIERs.
  • Pitch up to 15-20 degrees, then press 4 to rotate hover engines.
  • Pitch for 8-10 degrees attitude and hold.
  • When hover engines stop, press 5 (activates nuclear engines; +- 7.5km alt).
  • at 30km alt (when RAPIERs airbreathing stops) press 3 to switch engine mode.
  • After RAPIERs run out, gradually lower pitch (not too quickly or you won’t make orbit).

Other Keycommands:

6 - Solar panels/Radiators/drill
7 - ISRU
8 - Aerobrake
9 - Ladders/Antenna
