Abstract:
1. A compound engine system comprising: a rotary engine having a stator body having walls defining an internal cavity, and a rotor body mounted for eccentric revolutions within the cavity, peripheral walls of the rotor and stator bodies cooperating to provide rotating chambers of variable volume when the rotor body moves relative to the stator body, the volume of each chamber varying between a minimum volume and a maximum volume with a difference between the maximum and minimum volumes defining a displacement volume, the peripheral wall of the rotor body having a recess defined therein in each of the chambers, a volume of each recess being more than 5% of the displacement volume, the rotary engine having at least one inlet port and at least one exhaust port in successive communication with each of the chambers; a compressor section communicating with the at least one inlet port; and a turbine section connected to the at least one exhaust port.
