More Contra rotating props - Keep it cranking 😂 Aircraft equipped with contra-rotating propellers, also referred to as CRP, coaxial contra-rotating propellers, or high-speed propellers, apply the maximum power of usually a single piston or turboprop engine to drive two coaxial propellers in contra-rotation. Two propellers are arranged one behind the other, and power is transferred from the engine via a planetary gear or spur gear transmission. Contra-rotating propellers are also known as counte

What are COUNTER-ROTATING PROPS: There is a big difference between these two boats. The first boat shown has one prop for each engine. Each engine spins counter to one another to avoid side effect. If both props spin the same way in forward, the stern will drift to one side, making a difficult to handle. The other vessel has two engines with two props each. Each engine has its own counter rotating blades. #howtoboating #howto #boating #propellers #props #engines #blades #captain #sideeffect #wal
