The non-rotating axial-flow compressor airfoils in an aircraft gas turbine engine are called:

rotor blades
stator vanes
disc rims
compressor casings

The correct answer is: stator vanes

The correct answer is B stator vanes. Axial-flow compressors are a type of compressor used in gas turbine engines to compress air for combustion. They use alternating rotating and stationary sets of airfoils (also known as blades or vanes) to compress the air. The rotating airfoils are known as rotor blades, while the stationary airfoils are called stator vanes. Therefore, option A (rotor blades) is incorrect as it describes the rotating airfoils. Option C (disc rims) is also incorrect as it refers to the spinning discs that hold the rotor blades, not the blades themselves. Option D (compressor casings) is incorrect as it refers to the housing of the compressor, not the airfoils within it.
