Rob, where is the theoretical bottleneck in this engine with regards to hp; eventually would the e shaft tapers start to slip and take the keys with them? Or shear at a keyway first? Edit/Reply; I think it's interesting we have several well thought out opinions below, but no clear consensus. Rob we'd love for you to chime in! I am betting you have modeled all the internal components and know that the e shaft will hold 2khp (or have been assured it will by the original machinist). I am still wondering what fails first. The RPM vs Apex seal lifting is interesting, but as you stack rotors up to 6 lets say, I would bet that at a functional RPM the size limitations of the e shaft which cannot grow start to become an issue first. Also, it's not like he is gonna put this on an engine dyno to gently find the limits; he's gonna rev it to 6500 and 2 step the launch and he still doesn't have a slipper clutch. He'll stay in on the dyno up to 7k all wheel drive. If the clutch, driveshaft, trans and tires can hold 2k I would think the next thing in line is the e shaft.
@isarob032 жыл бұрын
I don't know much about rotarys other than what I learned from Daddy Dahm. It seems to me like apex seals are going to be an issue as indicated by the wear he polished out of the rotor housing in the beginning. I would think side seals would be the next weak point but once again, I don't know a ton about rotarys.
@evancourtney77462 жыл бұрын
My money's on the apex seals lifting off the housing's surface just after crossing the area where the two peritrochoid 'lobes' meet. Passing that point the rotor apex is traveling tangential to the peritrochoid surface so there isn't really any centripetal force helping the apex seal maintain contact with the housing when the housing shape needs the the apex seal to reverse direction; ie. radially into then out-of the apex seal slot. A loss of sealing here will cause a drop in compression and limit power. Also, the speed at which the apex seal needs to change direction is a function of RPM so the loss of sealing is the limiting factor there; the limited RPM limits overall engine power.
@md4luckycharms2 жыл бұрын
