TURBINE EXHAUST SYSTEM - DESCRIPTION AND OPERATION
__________________________________________________
1. General
_______
A. The engine exhaust system provides an efficient exit path for the exhaust gases. Major components of the system are the engine exhaust sleeve and engine exhaust plug.
2. Engine Exhaust Sleeve (Fig. 1)
_____________________
A. The sleeve is a tapered cylindrical structure extending aft of the turbine exhaust case and fairing with the engine side cowl panels. Its interior surface forms the outer contour of the exhaust nozzle and annulus. The forward bulkhead of the sleeve is bolted to the turbine exhaust case.
3. Engine Exhaust Plug (Fig. 1)
___________________
A. The engine exhaust plug is bolted to the inner flange of the turbine exhaust case. The plug, in conjunction with the engine exhaust sleeve, establishes the cross sectional area of the exhaust nozzle and forms the inner contour of the exhaust annulus. The plug is fabricated from contoured sheet panels.
