What type of compressor would you use if you needed to power aircraft?
A. Axial compressor
B. Centrifugal compressor
C. Rotary compressor
D. Reciprocating compressor
A. Correct. The most common use for axial compressors is in jet engines used to power aircraft and some ships.
B. Incorrect. Centrifugal compressors are best suited for continuous-duty applications such as ventilation fans, air movers, cooling units, and other uses that require high volumes but relatively low pressures.
C. Incorrect. Rotary compressors are especially useful in applications where the operating conditions (flow/pressure) vary greatly.
D. Incorrect. A common application for the reciprocating compressor is an instrument air system. They are also used for methane or off-gas compression (flammable gases).
