My mechanical design aim was to create a power for UAV,MAV, robotics, mini-generators; engine size is very small, can be forged or EDM etching method of mass production. Because the rotor around its axis, uniform rotation, so it can reach a very high speed, high power.
Currently, power machinery, achieve practical machine are wankel engine, RCV engine, and there is a traditional four-stroke internal combustion engines, two-stroke internal combustion engine, and so on. They have their advantages, but also have their shortcomings. Especially the mechanical size less than 1 cm, the disadvantages of exposure of particularly, RCV engine, the traditional four-stroke internal combustion engine and two-stroke engine with considerable difficulty processing, especially tiny part of the process is more difficult, the production cost is very high, the work reliability was really bad. Wankel engine’s parts relatively few, small size relative high reliability, but cutting machining is difficult, difficult to implement low-cost lot size
Production.while my engine rotor and stator's face is an irregular surface, machining difficult too, but the face is smooth, in small size, available material in plastic processing technology for low-cost of production and the use of plastic processing methods are forging, EDM etching, forging will not only enable low-cost production quantities, but also can improve the mechanical parts of the structure, part of the strength and surface finish. Adopting EDM etching, can improve parts of sealing and wear resistance, the specific method is: etch out a lot of fine grooves on the moving parts which need sealing, forming the labyrinth, with labyrinth seals, improve sealing performance. and on the sliding contact surface, etching a lot small pits, lubricants, as far as possible remain in these areas, to improve the machinery lubrication performance.
study the 3D images that I upload on to forums, that structure, you should understand that was not possible work, because the rotor projecting too sharp, not only the room’s sealing cannot be guaranteed, and the normal rotation of the rotor cannot be guaranteed. There are a lot of problems you can see, after all, is a previous primary design!
If you have the good suggestion, please tell me!

This is a neat design, in Australia there was a similair design principal except the combustion was by 5 cylinder axially spaced around the mainshaft.
sealing should not be to bad being a spherical motion, slice a sphere and what do you get? A circle of course, combine this with the pricipals of apex seals from the rotary.
I could imagine you will have to make lapping fixtures to bed down the seals before assembly.
Being a specialised design requires specialised tooling, so your thinking cap will have to cover those bases as well.
But going by the integrity of the cad work, design principals, I should say you would be well into that thought process.
One last word, get a patent ASAP!! Having this stuff in the public domain loses your intellectual property.
I wish you well and hope to see plenty of build up photos.
Thank you for your comment, my design is patented. I would most like to do is to create a valid prototype in order to further research,can you help me get in touch some persons or companies? get together to study of . I think It's a good engine for UAV,MAV,soldier power....
Have a nice day!
I would put together a presentation with 'powerpoint' and try to get an appointment with a representative of the 'orbital engine company' (ralph sarich).
His company is highly credible and has a wealth of patents on similar designs.
Or, failing this, maybe approach mazda, ilmor or rotax.
Really, you should stay confidential with who and what transpires as they could see this as an competitive edge.
You may even want to ask the moderators to remove this thread.
Thank you very much! if you can contact the engine research institutions, or engine manufacturing company, is a good thing!
Have a nice day!
skip it, and go brushless w/ lithium
Hi again fu, I am not in the sales game, this needs 'pitching' and you need to do some homework towards this. My understanding is, big organizations want a lot of information in a 20 minute sales pitch. Probably a working model, and a projected market, an understanding of manufacturing cost and designed to keep costs down.Thank you very much! if you can contact the engine research institutions, or engine manufacturing company, is a good thing!
I cant just jump on a plane at my own expense with no research or preparation and 'cold call' a goliath company for your big break.
Think of your design a seed, now the tree must grow.

What means is that?
Hi again Fu, i am getting an understanding of our cultural difference.
I was trying to use a 'analogy', sort of like a story along similar lines to describe a thought, or a situation.
I have worked in sales briefly, selling Supermax cnc mills, with no success.
But when talking to customers, it was important to relate, make them feel at ease while mindful of your sales goals.
I invented a few variants of the 4 cycle engine, not as good as yours though.
My main message is you must learn selling, maybe you already know.
Anyhow, pardon if my language previously seemed abrupt.
