65.14 Turbine Engine Exhaust Section
65.14.2 State the function of the exhaust section on a helicopter.
Exhaust Section
The exhaust section of a helicopter turboshaft engine is designed to discharge exhaust gases safely while producing little or no useful jet thrust.
Most of the energy in the gas flow has already been extracted by the turbines to drive the compressor and helicopter rotor system.
The exhaust system may diffuse or redirect the remaining gas flow to reduce residual thrust and prevent it from adversely affecting the helicopter.
