Full Plane/SSTO Guide here. More info here. Here are the things you need to balance: Gravity losses. Select your mission objective by clicking on links like "Low Orbit" or "Surface"! Adding more than 1 decreases the delta v and increases TWR. ... See also the aerobraking calculator. atomic_houseboat's Mission Flow Diagram alterbaron's KSC landing chart. I was wondering about the math behind the atmospheric system KSP is using. (Best way to picture this: imagine if your TWR on the pad were 1.00001. est la masse totale du vaisseau (en kilogrammes). Any TWR above 1.2 will work adequately for the middle stages, but most stock mid-stage engines and most balanced mod mid-stage engines have a good fuel efficiency setup for rapid burning, so I tend to go for a higher TWR like 1.5 again. subhumann's SSTO Ascent Profile. The reason your second attempt was more efficient was because you took advantage of the Oberth Effect and changed your velocity at a faster … No, there is no 'ideal' TWR in space since you are not limited by the time it takes to accelerate. I am currently aiming to develop my own KSP kOS autopilot for bringing every (or almost every (or some)) rocket into LKO. On utilise ici l'accélération de la pesanteur au niveau du sol =, / pour Kerbin). More charts for the other planets here. = ⋅ > Où est la force de poussée des moteurs (en newtons). KSP Flight Controls Keyboard Map (as of 0.22) by Trigger Au. And about the way of calculating the perfect inclination for a rocket of given mass, with certain TWR and speed, at given height. Ratio poussée-poids (TWR) → See also: Ratio poussée-poids. For craft larger than about 15 tons, the nuke is the most efficient engine delta v wise. This is a dV waste that your ship incurs because it's spending fuel fighting gravity rather than making the ship go faster. You'd sloooooooowly lift off, basically just hovering. tavert's Landing and Takeoff Delta-V vs TWR and specific impulse charts. Picking the "right" TWR will depend on the characteristics of your ship. Si le ratio poussée-poids (thrust-yo-weight ration, TWR) est inférieur à 1, la fusée ne décollera pas du pas de tir.
