How many stages do most present-day engines have?

• A. 4-8 stages
• B. 8-16 stages
• C. 16-24 stages
• D. 1-3 stages

Answer: (B)

Most present-day gas turbine engines typically have between 8 to 16 stages for the compressor section. This range allows for efficient compression of the intake air, which is essential for achieving optimal performance and efficiency in the engine. The number of stages is important as it balances the need for increased air pressure and volume while managing the mechanical complexity and size of the engine. Modern engines are designed with advanced materials and aerodynamics that enable them to operate effectively within this range, maximizing thrust while minimizing fuel consumption and emissions. Stages beyond this range, such as those in option D, would not provide sufficient compression for typical operational demands, while stages at lower end such as in option A may not meet the performance standards required for more powerful applications.
