3. Technical Data
3.1 Introduction
This chapter contains technical data of the engine (heat balance, flows, pressures etc.) for
design of ancillary systems. Further design criteria for external equipment and system layouts
are presented in the respective chapter.
Separate data is given for engines driving propellers “ME” and engines driving generators
“DE”.
