|---|---|---|---|---|---|
| show | The hot section and the cold section.
🗑
|
||||
| What are the two basic types of compressors that are used in aircraft turbine engines? | show 🗑
|
||||
| show | The stators convert some velocity energy into pressure energy and change the direction of the air so it is proper for the next stage of rotors.
🗑
|
||||
| What are three types of combustors used on aircraft turbine engines? | show 🗑
|
||||
| show | Two.
🗑
|
||||
| show | The turbine nozzle directs the hot gases as they leave the combustors so they will turn the turbine wheel with maximum efficiency.
🗑
|
||||
| show | A turboshaft engine that has a turbine wheel that is not used to drive the compressor of the gas generator section of the engine. This free turbine drives the propeller in a turboprop engine or the transmission and rotor of a helicopter.
🗑
|
||||
| Why do some axial-flow turbine engines have more than one set of turbines and compressors? | show 🗑
|
||||
| show | Anti-friction bearings, such as ball bearings or roller bearings.
🗑
|
||||
| show | An axial-flow turbine engine in which the first stage of compressor blades are lengthened, so they can force air around the outside of the gas generator portion of the engine.
🗑
|
||||
| Where can you find the limits of repair allowed for the compressor blades of an aircraft turbine engine? | show 🗑
|
||||
| show | If the engine is shut down while it is hot, there is a possibility that the shroud will contract around the turbine wheel and seize the rotor.
🗑
|
||||
| What is meant by a hung start in a turbine engine? | show 🗑
|
||||
| show | A start in which ignition occurs, but the internal temperatures go high enough that they can damage the engine.
🗑
|
||||
| show | A condition of permanent elongation of the turbine blades. Creep is caused by the high temperatures and the high centrifugal loading imposed on the blades.
🗑
|
||||
| How is the compressor of a turbine engine cleaned? | show 🗑
|
||||
| Where is water injected into a turbine engine for cooling purposes? | show 🗑
|
||||
| show | At the inlet to the high-pressure turbine.
🗑
|
||||
| show | These tubes allow the flame to travel from the cans that contain the igniters to all of the other cans when the engine is being started.
🗑
|
||||
| show | The mechanical blockage-type and the aerodynamic blockage-type.
🗑
|
||||
| show | Adjusting the fuel control to get the correct idling and maximum-thrust RPM.
🗑
