21. All of these additional devices have important uses in the control of the centrifugal compressor . 22. This acts as a centrifugal compressor to pressurize the cooling air before it enters the blade. 23. He tested the centrifugal compressor at Derby, and found a solution to the difficulties of surging. 24. Centrifugal compressors are common in very large applications.25. The engine began development in the late 1970s for the centrifugal compressors in its high-pressure compressor. 26. Ideally, centrifugal compressor impellers have thin airfoil blades that are strong, each mounted on a light rotor. 27. At the time most superchargers used a centrifugal compressor , so there was limited interest in the paper. 28. In this type of compressor unit, the centrifugal compressor is driven by a high voltage electric motor. 29. Centrifugal compressors have the advantage of being simple and lightweight, at the expense of a streamlined shape.30. To weigh the advantages between centrifugal compressors it is important to compare 8 parameters classic to turbomachinery.
