Agreed, but some said it was the same as the torqueshift device which DOES use springs.
Looking at past posts it's clear we didn't explain well enough what our innovations do. Some people think it's just another variable pitch...
I'm afraid that's the very innovation we're patenting and the problem that people have been trying to solve for decades i.e. totally captive...
You're correct that the hydrodynamics of the inner blade/hub area are a big mystery. We really don't know how the large gap that opens up at...
These designs only allow diameter variation within the recommended upper and lower limits for any propeller for a given engine. In effect they...
As I understand it, a diesel-electric is just a different way of extracting/storing energy. A propeller is a mechanism to apply that energy to...
Correct! Variable anything is good if justified by the extra complexity etc etc. Morphing of airfoil sections is also on the cards as you...
I think what you all neutral position is what others term "feather pitch" i.e. it imparts no thrust because the blades are at an angle that just...
You would need to be more specific in your question.
A dog clutch is pretty easy to implement on the vertical drive shaft. Manufacturers don't tend to do it that way because they also want to...
You don't. The prop will turn at startup but by placing the prop at feather pitch it will generate no thrust and won't move the vessel....
Oh OK I think I understand what you're saying- the engine start up is affected by the prop pitch that the engine stopped at? So if the prop was...
Very insightful comment and I'm a bit embarrassed that we haven't done much in the way of business planning. I guess it's the nature of...
If you look on the website www.ndjen.com I have posted an outboard lower unit mockup. Yes the blades are wrong and the range of movement is too...
Good point.
