4-11. In current U.S. Navy service, the single-shaft  turbine  engine  is  used primarily  for  what  purpose? 1. Driving ship’s service generator 2.  Propelling  aircraft  carrier 3.  Driving  auxiliary  steam  compressors 4.  Propelling  small  boats 4-12. What are the four major sections of a gas turbine engine? 1. Compressor, igniter, turbine, and hydraulic 2.  Compressor,  auxiliary,  combustor, and  turbine 3.  Compressor,  combustor,  turbine,  and accessory 4.  Turbine,  auxiliary,  hydraulic,  and compressor 4-13. What are the three types of combustion chambers? 1. Hot air, forced draft, and stationary 2.  Can,  annular,  and  can-annular 3.  Closed,  open,  and  stationary 4. Dual shaft, twin spool, and annular 4-14. The annular combustion liner is usually found on what type of engines? 1.  Dual-compressor 2.  Axial-flow 3.  Single-stage 4.  Dual-stage 4-15. In theory, design, and operating characteristics,  the  turbines  used  in gas  turbine  engines  are  quite  similar to the turbines used in 1. an electrical power generating system 2. a reciprocating power plant 3. an emergency generator 4. a steam plant 4-16. The ship’s propulsion plant can be operated from which of the following stations? 4-17. When compared to other engines, what is the gas turbine’s greatest asset? 1. Its low fuel consumption 2.  Its  high  power-to-weight  ratios 3. Its low maintenance cost 4. It ability to resist corrosion 4-18.  Internal  combustion  engines  convert heat energy into what other type of energy? 1. Mechanical energy 2.  Hydraulic  energy 3.  Electrical  energy 4.  Potential  energy 4-19.  The  back-and-forth  motion  of  the pistons in an engine is known as 1. combustion motion 2.  mechanical  motion 3.  reciprocating  motion 4. rotary motion 4-20. In the internal combustion engine, what  changes  reciprocating  motion  to rotary  motion? 1. A crankshaft 2. A connecting rod 3. Both 1 and 2 above 4. A piston 4-21. Which of the following parts will NOT be found on a diesel engine? 1.  Pistons 2.  Valves 3. Spark plugs 4. Connecting rods 4-22. In the internal combustion engine, what are the four basic strokes? 1. Intake, extension, power, and exhaust 2. Intake, compression, power, and exhaust 3.  Intake,  reduction,  expansion,  and exhaust 4.  Compression,  expansion,  extension, and power 1. The local control console 2. The central control console 3. The ship control console 4. All of the above 20
