The following table provides an overview of all SRBs in KSP. Boosters are usually mounted on radial decouplers so they can be jettisoned as soon as they burn out. Therefore they are typically used in the first stage of a rocket when the thrust is needed to get an initially heavy rocket off the ground. Just because KSP2 has lots of extra texture memory to play with and are willing to model things in like this in great detail, doesn't mean you should expect them to know that there's supposed to be a combustion chamber, not just injectors spraying fuel into an open nozzle. Using tweakables you can decrease the amount of solid fuel in the booster or limit the amount of thrust at launch and thus decrease the burn time or twr.Ĭompared to other rocket engines, solid rocket boosters offer a high thrust-to-weight ratio, but low specific impulse (fuel efficiency). Since solid fuel cannot be transferred between parts, a burnt-out solid booster cannot be reignited. Once ignited, they cannot be shut down or throttled and will burn at maximum thrust until their entire internal fuel supply is spent. SRBs incorporate engine and fuel in a single part. SRB, sometimes simply called solid booster, is a rocket engine powered by solid fuel. ) this behaviour should be considered at the more advanced engines, as it can easily lead to a rapid unscheduled disassembly.A size comparison of the available SRB partsĪ Solid rocket booster, abbr. As for additional concepts, you may want to add maneuver engines like on big ships. Jet engines are the answer lol well, every engine does. However, as more thrust most often leads to more velocity ( leading to more thrust. All Discussions Screenshots Artwork Broadcasts Videos Workshop News Guides Reviews. The extra large hydrogen tank has 20 tons of fuel while the extra large. Hydrogen is not dense both in real life and in Kerbal Space Program 2. New engines with metallic hydrogen may be used for interstellar travel. Hydrogen is used for efficient engines like the LV-N 'Nerv' and also LV-SW 'SWERV'. The thrust gain, design speed and max speed increases with thech level, up to 850% gain at mach 3.7 on the R.A.P.I.E.R. Hydrogen is a fuel in Kerbal Space Program 2. The three high-speed engines on the other hand gain a considerable ammount of thrust up to their design speed, gradually lowering to zero approaching its high top speed. The three low-speed engines do not gain thrust with speed, but rather lose about 20% around mach 0.5, gaining about full thrust again at around mach 1.5, dropping sharply to zero around mach 2. As of version 1.0.5, the 6 jet engines can be divided into low-speed and high-speed engines, regarding their thrust-to-speed behaviour. One large difference of the jet engines compared to conventional rocket engines is, that the thrust also greatly depends on the velocity relative to the atmosphere around. Jet engines also produce heat (I was trying to fly a plane but my flaps exploded from overheating). The engine, along with its four-nozzle counterpart, the S3 KS-25x4 'Mammoth' Liquid Fuel Engine, has moderate efficiency in vacuum and the. It also has a relatively high thrust to weight ratio. As this may happen unevenly it can cause severe spinning and potential loss of the craft. The Vector is the heaviest and most powerful 1.25m engine by far, with a mass and thrust between that of the 2.5m 'Skipper' and 'Mainsail' engines. When the intake air level isn't checked periodically a jet engine tends to flame out and suddenly doesn't generate any thrust. In short, I think KSP2 developers should consider introducing more fuels, and, make some engines multifuel capable, either in VAB, or in the field (as well as make well researched decisions on which engines are multifuel, how, and why). Jet engines don't consume oxidizer, so the use of rocket fuel tanks is very wasteful because they come with an full oxidizer tank adding additional mass. The flame out effect on a Basic Jet EngineĪs of version 0.18 jet engines require intake air to run, provided by air intakes.
