  • Halfbakery: Counter-Rotating CrankshaftDiese Seite übersetzen

    In a straight four, the back two cylinders would rotate clockwise, and the front two would rotate counter-clockwise. You could also put these gears between each cylinder, so that every crank would rotate the opposite way of the ones on either side. This would be a lot more complex and expensive, though.

    28.04.2005 · Really don't understand this point. If (say) a gust caused undemanded roll, i don't see how this would resist input. If anything counter-rotating systems are normally done to avoid gyroscopic coupling, thus reducing effective rotational inertia. The two counter-rotating rotors will avoid cross coupling, simplifying pilot workload.

    If tubes were submerged 50-100 meters below the ocean surface, ships would pass over without any trouble, and storm activity wouldn't have an impact. They would be neutrally buoyant being made from heavy strong materials, tethered to the sea bed where possible, and may have propellers to counter-currents in-between.
