I Am Trying to Make This Thing

When you say "hinged", do you mean that the rotor blades must be movable relative to the rings?

If they are stationary and do not need to move relative with the rings, then this sound like a conventional machining job that must be supplemented by a secondary operation on a 3- or 4-axis travelling wire EDM machine so the thing can be made as one (1) piece and preserve the grain integrity of the metal. Without seeing a concept drawing it is difficult to determine an economical manufacturing solution.

Sounds like something we might like to make here. Are you ameanable to an outside source? If so, pdf me a sketch of what you need and I wil have one of our design engineers look at it for feasability/cost ect.

Depending on how large the rotor is, stampings may be the way to go. We can easily stamp a ring with sections cut out and install stamped hinged flaps. Size and application will need to be known. We specialize in prototype and low volume stamping and I would be happy to give your project a look to see if it is feasible to construct any part of it as a stamping. If you will ned more than just a few pieces, stamping is most likely to be the most cost effective method. We can roll the hinged area right in to the stampings.

The Thing that you are describing is very ambiguous. I am not sure that anyone understands. Every answer asked for a picture. What I am seeing is an outer ring hinged to the rotor blades hinged to an inner ring. Is this the Thing. More detail is always better in this forum. How big, what material, and how high the RPM. What is the purpose of the hinges, etc..

Hi,

I assume you will have rotating vanes across the annular section of two bands (rings). They will be like spokes on a wheel but their angle can be adjusted like a heliocopter by puting a shaft through the vane between the bands. In any case it is a difficult thing to do. The best spproach is to determine the limit of CM, UM and, Head to create the vane profiles and adjust thrust with speed of the driver. Your thrust control can be an iris style forcing cone like the one you see on an F-16.

A drawing is essential, as are specs: Is 75,000 rpm high rpm? Is 10,000 rpm high rpm? Does "hinged" mean pivoted so that the blades can be adjusted for angle of attack? etc. etc.

"I need to make to concentric rings with tapered "rotor blade sections" hinged between them. it needs to be able to withstand high rpms, any ideas???"

Hey, that sounds just like my "Captain Midnight Decoder Ring"! When I put it on the record player spindle at 33-1//3 rpm it would withstand 45 and even 78 rpms without flying off!

Listen, with your description, that could be anything from a micro-machine on a silicon wafer to some megalithic monstrosity featured on "Modern Marvels" on the History Channel!

More than likely, it'll be something like what the "Mythbusters" would come up with!

Sounds like when one of our customers is trying to describe a piece of hardware he wants to know if we have or can make over the phone, but does not want to let on what it is for because he has some weird idea of "patent rights" he does not want to give away by disclosing "too much" information. Or the military contractor who wants a quote on a part, but won't send a print, because it is "classified" Confidential or Secret.
