In upwind sailing conditions, bulbs of canting keel sailboats operate close to the water surface and therefore induce non-negligible changes in the wave system, thus influencing the wave making resistance of a sailboat. The bulb could pr... K Hochkirch,C Fassardi 被引量: 6发表: 2007年 Optim...
words, it slips sideways less. Obviously, when sailing to windward we are trying to reach a destination upwind, and any sideslipping that pushes us downwind is undesirable. The slower the velocity of the fluid flowing past the ‘airfoil,’ the less efficiency it has as a lifting surface. So...
Physics Involved In The Working Of Sailboats. The physics behind sailing is very interesting, as sailboats do not require wind to be blowing from behind in order to move. It is actually possible for the boat to move forward even if the wind is blowing in from the sides. How does that wo...
A related bit of physics: sailing upwind ≡ sailing directly downwind, faster than the wind. A physics lesson without words. Explain what you see. How sure are you? How do you know? An analysis of clocks that use pulses of light to keep time. A special relativity puzzle, involving ...
