During World War II, Daimler-Benz explored an unconventional fighter concept built around a massive experimental V16 engine. Instead of placing the propeller at the nose or tail, the design mounted ...

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 ...

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).

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 ...

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 ...

The centrepiece of the new construction project for the Polarstern's successor is now taking shape: by the end of August, TKMS, Wärtsilä, Steerprop and Aker Arctic had inked the contracts for the ...

It's fairly common knowledge that when a supersonic aircraft approaches the sound barrier, what follows is the sonic boom. This transitory period between subsonic and supersonic, known as transonic ...
