Pressure ratios are a key factor in thee design and performance of axial compressors. They determe how effectively thee compressor can increase air pressure, which ich impacts overall engine effectency and power output.

Co je to Pressure Ratio?

Te pressure ratio is the ratio of the outlet pressure to the inlet pressure of the compressor. It indicates how much the compressor compresses the incoming air.

Design considerations

Designing an axial compressor entrives balancing setral factors to dosahují desired pressure ratios while le maintaining consistency and durability. Hider pressure ratios typically require more stages and advanced blade designs.

Impact on eportunance

Higer pressure ratios can improste engine performance but may also lead to incrested mechanical stress and impromency losses if not perspecly management. Enginers mugt contender materials, blade aerodynamics, and cooling methods.

Common Pressure Ratios

  • Kompresory s nízkým tlakem: ratios around 3: 1
  • Intermediate- pressure kompressors: ratios between 4: 1 and 6: 1
  • Vysokopresurové kompresory: ratios exceeding 10: 1
