This is AWESOME, i love these 4rotor projects. You and BigYellowCat should somehow team up and make something insane

 

Thanks, I'll see if I can open up a topic about the engine soon.

 

you get two thumbs up for ingenuity, however, one of those thumbs i have to insert in your rectum due to this only being accomplished by a billionaire

 

There is alot of good reading to do in here! I will be following through over the next couple of days.

 

hate to bump, but have you been putting any thought towards the combined rotors idea? :o

 

Not a lot, I abandoned this idea and started building a 'regular' 4-rotor. I still think this would work though, but there are some downsides. RPM limit is lowered because of the larger rotating mass, the amount of power isn't going to be great because the ports are going to be small in proportion to the chamber volume, you can go semi pp to avoid this, but then you lose the advantages of a side port engine. And the amount of work and money involved is the same or more than when building a 4-rotor, which sounds wayyyy gooder.

I am thinking about another engine design though, with the goal being creating a high output n/a rotary engine with fuel consumption similar to a normal rotary using a lot of 13b engine parts, eccentric shaft, rotor housings, rotors ect. They are just thoughts and some 3d drawings at the moment, so I'll keep them to myself, but I'm pretty exited about it. Ah well I'd better finish my 4-rotor first before thinking about the next project
