Turbine Engines Flashcards
How are the removal of a reciprocating engine similar to the sections of a turbine engine?
Intake = air inlet section, compression = compressor section, ignition and power = combustion and turbine sections, exhaust = exhaust section.
What type of turbojet engine is commonly used in commercial aviation due to lower noise and better fuel consumption?
High-bypass turbofan engines.
What four types of gas turbine engines are used in aircraft?
Turbofan, turboprop, turboshaft, and turbojet.
What are the two types of turbine compressors?
Centrifugal flow and axial flow.
What is meant by trimming a turbine engine?
Adjusting the fuel control so the engine develops the correct idle and trim speed RPM.
What type of equipment should be used to determine that a turbine engine is performing up to the standards specified by the engine manufacturer?
A JetCal analyzer/trimmer has all of the instrumentation and cables to determine the EGT, EPR, and other parameters specified by the engine manufacturer.
What is meant by a hot-section inspection?
An inspection of the hot section of a turbine engine. The hot section includes the combustors, the turbine, and the exhaust system.
What is meant by on-condition maintenance of a turbine engine?
The monitoring of the engine performance at regular intervals and determining when maintenance is required based on certain operating parameters specified by the engine manufacturer.
