Hello all.
Here is a Wankel-like Rotary Engine:
The working surface whereon the seals abut is not a “cylindrical” surface but a 3D curved surface ending smoothly / tangentially on the side flat surfaces of the casing.
The typical “Wankel sealing grid” (wherein each combustion chamber is sealed by a set of two side seals, two apex seals and four button (or corner) seals) can be replaced by a single piece seal per combustion chamber.
Here is a PatWankel wherein the working surface is on the inner body (say as in the Liquid Piston engine):
One seal per combustion chamber, as in the reciprocating piston engines.
This five “cylinder” PatWankel rotary ( stereoscopic view, as at http://www.pattakon.com/pattakonStereoscopy.htm ) :
has two combustions per rotation of the inner body, i.e. as much as a two-rotor Wankel Rotary (say, Mazda RX-8).
Does the oval seal at bottom middle remind the Honda NR750?
Imagine this PatWankel engine at the back of an airplane pushing forwards:
The outer body (that with the cooling fins) spins at 4/5 (80%) of the speed of the inner body:
There is no eccentric shaft.
There are no balancing webs.
However it is perfectly balanced.

Thoughts?
