There's a reason why most propeller aircrafts use front-facing engines. And it's not just for the iconic aesthetic they've ...

The water pump propeller has gone through several improvements in its design. This latest design is made to channel a high volume of coolant through the engine. 6.

The open water characteristics for a large systematic series of Controllable Pitch Propellers (CPP) were recently measured at MARIN… Saturday, June 14, 2025 🔍 ...

Water “slides” off the propeller much more easily (which also makes the drive quiet). Better yet, the device is harmless to water fauna and flora. The initial design targeted low and medium ...

In water, that presents great challenges: “When I would design a propeller for an airplane, it was a straightforward problem. You know how they’re going to work, plus or minus a few percent, and ...

EcoNavis Solutions, a spin-off from the University of Strathclyde in Scotland has begun production of its patented Eco Boss ...

By providing power to a propeller it can impart motion to the air and can therefore couple human power output to provide propulsion for an airplane. For boats, a propeller used for propulsion can ...

Using nothing but his own leg power to turn the craft's 10-foot (3-m) air propeller, he got it up to a speed of 18.5 knots (21 mph/34 km/h), breaking the human-powered water speed record in the ...

The propeller design is inspired by a shaftless water pump propeller and is capable of generating effective propulsion in liquid environments.
