1) If you rotate wing panels 90 degrees, they won't do anything.Stock KSP wings only produce lift from air flow perpendicular to the part (not the plane!). Wing sweep does matter in KSP, but not like in real life.Only thing that changes is your plane is harder to roll. Wing aspect ratios don't matter much without FAMod, the same wing pieces give the same lift.Same goes for elevons (but less important). What this means is Canards don't stall before the main wing in KSP, unless you give them a notch of trim-up rotation in the SPH.KSP lift model is a simple curve - wings give tiny ift at zero AOA, lots of lift at 20 degrees, and less lift after that.I think you understand it fine, and the explanation in the tutorial is correct however, make sure to differentiate between total drag force and the maximum_drag value. However, the craft with 4 tanks will have twice as much drag as the one with 2 tanks, because it has twice as much mass.įor a craft with two fuel tanks, one with maximum_drag = 0.2, the other 0.1, the average maximum_drag of your craft will be 0.15 (mass averaged), and the total drag force will be 75% of the original 2 fuel tank craft. 4 fuel tanks, both craft will have a maximum_drag of 0.2 the average maximum_drag of each vessel is 0.2. This is worked out for each part, where maximum_drag, mass and surface_velocity are part-specific, air_density is based on altitude, and the DragMultiplier is a constant factor that can be ignored for our purposes.Īssuming all fuel tanks have the same mass for this:įor your example of 2 fuel tanks vs. Here's the drag equation:ĭrag force = 0.5 * air_density * surface_velocity 2 * maximum_drag * mass * FlightGlobals.DragMultiplier I think your confusion is that Supernovy is talking about the arbitrary 'maximum_drag' factor that goes into the drag equation, and that you are thinking in terms of 'drag force' which does increase with the number of parts.
