Pratt & Whitney Rotary Engine Patents!!
Did you guys know Pratt and Whitney is working on rotary engines?? There are lots of recent (2010-2018) patents related to or mentioning wankel rotary engines.
They have patents for rotors, apex seals, intake and exhaust ports, direct injection with pilot chamber, compound setups (turbine connected to eccentric shaft), you name it! I just found out about it.
