Shadow Shield Case Study

We’re back with part two. This time, we improve on the current design and test it. Ship fail As it turns out, the ship we left in part one doesn’t actually work in KSP—the “shadow shield” part blocks the flow of propellant from the tanks into the reactor. However, the annular truss segment from NFT has two nodes to place parts, so I just move the MHD generator to one node, and the shield to another, while sticking the reactor to the generator. That fixes our problems, and we can actually commence testing. I also enlarge the arcjets, since I realized they would be way too small to be useful. I also mount four dual-nozzle thrusters for forward and backward motion, as well as a few more fuel tanks of hydrogen gas for the thrusters. In orbit…show more content…
Additionally, I enlarged the nozzle size—this was the main problem relating to low thrust. Issue I was fairly convinced that this would be the end of my troubles. Alas, this was not to be, as the reactor would die within seconds of the main engine activating. For some reason, the charged particle count would drop to zero, and I’m not exactly sure why. The solution seems to be swapping out the MHD for a charged particle electric generator part, for whatever reason. There also seems to be an issue with the ship spontaneously exploding in spectacular fashion on the launch pad, though this issue appears intermittently. Finally, the ship was good to go, and produced much higher thrust with a gigantic 15 meter wide reactor. The target for this test run is Jool, which is thankfully located in a rather convenient position, with the terminus at one of the great orbital habitats of Tylo, home to many thousands of residents and visitors. fix This time, the vessel accelerates out of Kerbin’s gravity with no issue, with an Isp of 51,000 and a thrust of 870 kilonewtons. I continue to accelerate the ship towards Jool, until a little past the midpoint, where the vessel is flipped to begin the deceleration. Why did I not do a flip and burn at the midpoint? I was accounting for the consumption of the liquid hydrogen propellant—as the ship spent fuel, the acceleration would increase, so the same amount of burn time would be more effective. At
