"Return-to-KSP" SSTO design(s) & questions
Solarapple posted a topic in KSP1 The Spacecraft Exchange
So after a summer-long hiatus I've decided to return to KSP to conquer Kerbin's moons, Duna/Ike, and Laythe. So I'm gonna have an SSTO carry base parts which are then taken and landed by a tug and a sky crane. Here's the issue: solar cant into space. I'm currently trying to make an MK2 spaceplane design for carrying 2t to orbit and returning. When burnout happens, I'll run out of rocket fuel at 25 kilometers above Kerbin. I've tried these ascent profiles: 45 degrees on takeoff, 25 degrees/10 km, 10 degrees/15 km 40 degrees on takeoff, 35d/600 m/s or 5 km, 30d/1000 m/s or 10km, 20d/? m/s or 15km, leveling at burnout Same as previous but no leveling (20 degrees/20km) 30 degrees entire flight SSTO designs: 6x Rapiers, 8x air intakes, very fast 4x Rapiers and 2x 45s, 4x air intakes, very slow (not pictured) 4x Whiplashes and 2x 45s, 6x air intakes, in-between speed Images below: So I need help perfecting this design because I also want to make an Mk3 part 40t ssto to go along with it. What are good parts for SSTOs depending on design? Engines (rocket and jet)? Air intakes? Wings and control surfaces? Stability (SAS)? My SSTOs are pretty agile because of the 1.25m SAS. What's a good spaceplane design for SSTOs? CoM and CoL distances? Position of wings? Fuel weight? Fuel oxidizer amount? And lastly, What is the best ascent profile depending on design? Please respond if you have answers to ANY of these questions. I could really use the help.
