Beschreibung
Zusammenfassung:	The invention discloses a fan and an aero-engine, the fan comprises a first rotating shaft, a plurality of first blades, a second rotating shaft and a plurality of second blades, and the first rotating shaft drives the first blades to rotate; the second rotating shaft drives second blades to rotate; the first blade is located on the front side of the second blade, the radial height of the first blade is smaller than that of the second blade, and the highest speed of the first blade and the highest speed of the second blade are both smaller than sound velocity. The first rotating shaft drives the first blade to rotate, the second rotating shaft drives the second blade to rotate, and the radial height of the first blade is set to be smaller than that of the second blade, so that the first blade and the second blade can rotate at different angular speeds, and the rotating speed of the first blade can be larger than that of the second blade; the highest speed of the first blade and the highest speed of the second
