I think he's trying to say that he wants to add a third rotor to a
'regular' 13b for the compounding.

Although in principal the 'simplicity' of the system sounds appealing,
the losses of the compression stroke would be huge in comparison to a
turbine of any reasonable size to absorb the energy of the exhaust.

Another problem is the weight of an extra rotor, aluminum housing, and
extra long E-shaft.
