Specifications for the T74-CP-702 engines used in Army aircraft are summarized in the
INLET AND COMPRESSOR SECTIONS
The following subparagraphs discuss the inlet and compressor sections. An exploded view of
the T74-CP-702 engine is shown in figure 9. 4.
The compressor inlet case, shown in figure 9.5, consists of a circular aluminum-alloy
casting; the front forms a plenum chamber for the passage of compressor inlet air. The rear portion,
which consists of a hollow compartment, is used to house the oil supply. A large circular steel screen
(item 11 in figure 9.4) is bolted around the air intake and the rear of the gas generator case to prevent
foreign object ingestion by the compressor.
