Swiss marine giant ABB has spent more than a decade developing a radically different Voith-Schneider take on a marine ...

The action of a propeller is that of a rotating wing where the lift provided by the wing is the desired thrust for propulsion. The blades also have an associated drag which reduces the overall ...

HRL Laboratories proof-of-concept delivers quiet, reliable propulsion for marine applications similar to the fictional ...

According to NASA, the word propulsion “is derived from two Latin words: pro meaning before or forwards and pellere meaning ...

It also provides up to twenty percent more thrust, which can shorten heavyweight ... while noting the propeller system has already completed more than one million flight hours.

The NP2000 propeller system upgrade has greatly revitalized ... Collins Aerospace stated that the NP2000 provides “a 20% thrust increase during take-off, a 20 dB sound reduction in the cockpit ...

The problem becomes one of propellers. Standard propellers are designed to create thrust in one direction only. Every quadcopter uses two clockwise rotation and two counterclockwise rotation ...

That seems to be the theme of [Bitluni]’s latest build, a simple (and hacky) propulsion system for a stand-up ... He designed and printed a very simple propeller, which he intended to power ...
