Thus sounds more of a sales pitch

They are currently more expensive to buy.

Will this type of Propeller be used on Naval Warships, like Carriers, and the new Frigates and Destroyers?

I know that some cargo vessels belonging to the massive shipping companies are testing them as I saw a video a while back with one being fitted to a Maersk vessel during major refit. So once it's been verified that they are worth the hassle and prove their efficiency they'll probably be used everywhere. I expect DARPA are sciencing the he'll outta them to find the best type for each vessel or aircraft.

It would be interesting to see how wel the old Chinook helicopter would perform wt Toroidsl rotord

They're props milled on 5 axis mills, yes the mills themselves are extremely expensive. But paying a shop to create the part would be cheap. These are astonishingly price gouging per unit piece. MIT creates them and 1 USA company make them....hmmmm, essentially that is the government, selling a few is just a cover. I'm not evil enough to figure out the why, not a mental deficiency, it's a block of the heart. Perhaps I don't really wanna know why.

So what is the failing points of the Toroidal Propeller? You haven't really addressed those points. I'm sure there are draw backs but exactly where?

There are no failing points or draw backs compared to traditional props. It's a more efficient prop that can provide lower volume when it comes to high frequency noise, but also provide more thrust at higher RPMs (due to lower friction and better efficiency). The biggest problem is the material and construction. People that are 3d printing them or doing molds, and doing tests, are often failing due to the scaling issue with more malleable materials. These props need to be made with very expensive manufacturing techniques and materials that are not available to the public. MIT has a great writeup on it, and these backyard "engineers" are too dumb to understand any of the contextual math and physics.

the drone propellers don't mitigate much sound

So what happened to it? Did the industry go with it? It'd be nice to have the title question answered.

Expensive to manufacture and produce.

When will submarines upgrade to this technology?

They have been using this technology for almost a decade.

Who would make these?! They aren't easy for industrial production.

I Actually Looked at buying Toroidal Propellors for my boats (pre-covid)... I took one look at the Price and said "HARD PASS". They shot themselves in the foot by pricing a single propellor at more than the price of entire leisure boat, motor, and fixtures and fittings. You totally skipped over the mid to High five digit price per propellor! To have captured the market, they should have been a minimum of 50% or more less than the price of the old cavitating types...

Maybe they're still an option for 3d printed drone propellers

No one says first anymore

Those flying taxis will never happen btw 🙄

So, bottom line, as always - we need to wait for patent to expire before we can get one. Same story as always.

Neat commercial. You may want to add a skip button though. 15 minutes is a bit long for an ad.

None of this is accurate. I did a video extensively looking into the patents and testing the actual propellers and it's all garbage
