Explore: Contrarotating Propellers

Aircraft equipped with contra-rotating propellers (CRP), coaxial contra-rotating propellers, or high-speed propellers, apply the maximum power of usually

aircraft propeller was pioneered by the Wright brothers. While some earlier engineers had attempted to model air propellers on marine propellers, the Wright

racing (see River Marathon). Pump jets have some advantages over bare propellers for certain applications, usually related to requirements for high-speed
