The engine internal air system is outlined as those airflows that don’t directly contribute to the engine thrust. The system has many vital functions to perform for the safe and economical operation of the engine. These functions embody internal engine and accent unit cooling, bearing chamber waterproofing bar of hot gas bodily process into the rotary engine disc cavities, management of bearing axial hundreds, management of rotary engine blade tip clearances (Part 5) and engine anti-icing (Part 13). The system conjointly.

EASA Part 66 Modules
2. associate increasing quantity of labor is completed on the air, because it progresses through the mechanical device, to lift its pressure and temperature. Therefore, to cut back engine performance losses, easa part 66 modules the air is taken as early as doable from the mechanical device coterminous with the requirement nongovernmental organization of every specific perform. The cooling air is expelled overboard via a vent system or into the engine main gas stream, at the very best doable pressure, wherever a little performance recovery is achieved.
3. a vital thought at the planning stage of a turbine engine is that the have to make sure that bound components of the engine, and in some instances bound accessories, don’t absorb heat to the extent that’s prejudicial to their safe operation. The principal areas that need air cooling are the combustion and rotary engine. discuss with half four for combustion cooling techniques easa part 66 modules.
4. Cooling air is employed to regulate the temperature of the mechanical device shafts and discs by either cooling or heating them. This ensures a good temperature distribution easa part 66 modules and therefore improves engine potency by dominant thermal growth and therefore maintaining minimum blade tip and seal clearances. Typical cooling and waterproofing airflow are shown in fig. 9-1.

5. High thermal potency depends upon high rotary engine entry temperature, that is restricted by the rotary engine blade and nozzle guide vane materials.
Continuous cooling of those parts permits their environmental operational temperature to exceed the material’s temperature while not touching the blade and vane integrity. Heat physical phenomenon from the rotary engine blades to the turbine disc needs the discs to be cooled and therefore stop thermal fatigue and uncontrolled growth and contraction rates easa part 66 modules.
