EXHAUST - DESCRIPTION AND OPERATION
___________________________________
1. General
_______
A. The exhaust system receives and discharges the fan and turbine air
through separate propelling nozzles to the atmosphere at a velocity and
direction to produce the required thrust.
2. Turbine Exhaust (Fig. 1)
_______________
A. The turbine exhaust system provides an efficient exit for the turbine exhaust. The turbine exhaust consists of hot, combusted gases exiting the low pressure turbine at high velocity. The major components of the turbine exhaust system are the turbine exhaust sleeve and turbine exhaust plug. Turbine exhaust accounts for 21 percent of forward thrust.
3. Fan Exhaust (Fig. 1)
___________
A. The fan exhaust is high velocity exhaust exiting the fan or first stage
compressor. The fan exhaust provides 79 percent of the total forward
