SINTEF has now designed and manufactured new measuring equipment for model testing of contra-rotating propellers. This could be good news for many large ships. “We see that propulsion efficiency ...

Researchers at SINTEF have now designed and built new measuring equipment for testing contra-rotating propellers, which are propellers that rotate in opposite directions. This could be good news for ...

Sharrow's extraordinary looped propellers were already some 30% more efficient than traditional designs – and now the company has put two of them together into a coaxial, contra-rotating prop that ...

At the very crux of engineering is the desire to problem-solve, optimize, and squeeze out every bit of efficiency possible from the system being built. Aircraft design and aeronautical engineering ...

Finnish propulsion specialist Steerprop has inked a deal to deliver its next generation contra-rotating propeller azimuth propulsion units to Lloyd Werft Bremerhaven The shipyard is constructing a ...

New features for the industry-standard resistance and propulsion software, HydroComp's NavCad. Many contemporary marine vehicles are being outfitted with contra-rotating propellers (CRP), and naval ...

Abstract: A contra-rotating propeller (CRP) offers higher propulsion efficiency compared to a single propeller. This paper presents a novel underwater CRP propulsion system that integrates a permanent ...

What became the Aeroproducts Propeller Company began in 1935 as Engineering Projects, Inc. of Vandalia, Ohio. It was founded by two brilliant engineers, Werner J. Blanchard, who spent several years ...
