(11) Recouperator. The function of the recouperator, also called
regenerator, is to transfer heat from the exhaust gases to the air entering the
engine. This process allows the incoming air to expand prior to combustion.
fully expanded airmass with maximum velocity. The recouperator is
cylindrically shaped with a hollow passageway through the middle. Triangular
and ovalshaped ports are placed alternately around the perimeter and pass
through the length of the recouperator (Figure 123). Two different types of
plates are alternately stacked to construct the recouperator.
