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

Steerprop will deliver its new Contra-Rotating Propeller (CRP) azimuth propulsions to Lloyd Werft Bremerhaven GmbH for a new research vessel being built for the German Aerospace Center (DLR).Measuring ...

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 ...

Finnish propulsion specialist Steerprop has been selected to deliver its new next generation of contra-rotating propeller (CRP) azimuth propulsions to Lloyd Werft Bremerhaven GmbH, which is building a ...

Designed and tested with BETA Technologies, it’s first propeller specifically for advanced air mobility (AAM) aircraft. Hartzell Propeller designed specifically for advanced air mobility (AAM) ...

If you have ever observed a propeller plane closely, you might have noticed the propeller is slightly angled to the right. The angled engine and propeller can seem jarring, considering symmetry is ...

When you picture a propeller-driven aircraft, you probably imagine a single engine plane with the propeller spinning at the front. There's a good reason for that, as the front-facing design has proven ...

The Rotating Detonation Engine being developed by Pratt & Whitney has no moving parts, which reduces complexity and costs, and could help enable high-speed, long-range flight with increased efficiency ...
