A better look at that funky new Sharrow prop

[home made tunnel]

Saw the ad on Facebook. They’re really dumping $ into the advertising. I’m pretty spatially intelligent, but even this thing hurts my brain lol

under water shot would be cool running

Agee .. like the tests you see with dye in the water, Im not sold on this thing.. seems like there is alot of blade area at the outer ring (Drag) thats not directly going to convert horsepower to linear thrust.. almost looks to be negative pitch in some areas of that curve.. Time will Tell..

Has anyone done comparison tests against a "common" prop like a Mercury Trophy or Tempest?

Is it designed for surface piercing applications?

[LakeFever]

Turbine. Its the tip the makes the difference. The cost is dragging the supporting blade down the backside along for the support requirement. The machining there is where they won the battle imo by finding that slippery place in the prop wash perhaps to let it cost less than the tip cupping edge gains. My hat goes off this must have taken some diligent testing to perfect.

Just a theory keep in mind but I tend to see mechanical/heat function almost instantly for whatever reason I dont know I just do. I'd be curious to hear the designers input on this over time it will all come to light. If anyone catches this thread? Bump it, and we'll see if Im on track or off in yonkers. Ha

As above, time will tell

looks like it would be useful if you needed to make a 55 gallon drum of scrambled eggs...

That would be way too easy.

Was curious about the testing too

I'm sure we'll be seeing them on six drives like tomorrow

Lets see it in action

I feel that this design will be creating more slip due to a "hole" in the face of the blade. Like many, I'd want to see an underwater test. It may just turn out to be another gimmick.....like magnets for your fuel line that give you 100mpg

Looking at that it appears to me that the vortexes are larger. I'm like Wildman. I want to see a side by side comparison.

Ya mean they DON"T WORK?

Looking at that prop gives me a headache............

They should include a set with every bottle of ACES.

I think that hole cut thought earlier is how it works. Loading the top of the hoop so to speak. The load is meant to go onto the shovel up top and the rest of the blades are there to feed it, and support it.


Like this, with conventional prop spiral release

I'm still with the scrambled eggs.

Who knows, maybe I am too :eek:
