Double swept rotor blade with limited taper

Double swept rotor blade with limited taper

The blade has an internal zone (ZI), a sweep-forward zone (ZFS), a sweep-back zone (ZBS) and an external zone (ZE), successively along a reference beam (R). A separation limit between the zones (ZI, ZFS) is 0.60 times the beam. A taper ratio of the zone (ZBS) is between 1 and 2, and the external zon...

Zusammenfassung:The blade has an internal zone (ZI), a sweep-forward zone (ZFS), a sweep-back zone (ZBS) and an external zone (ZE), successively along a reference beam (R). A separation limit between the zones (ZI, ZFS) is 0.60 times the beam. A taper ratio of the zone (ZBS) is between 1 and 2, and the external zone also has a taper ratio. The zone (ZBS) has a constant chord equal to a chord of an outer section of the zone (ZFS).
