1. A partitioned rotor blade for a wind energy system, the partitioned rotor blade defining a longitudinal axis and comprising:
at least a first rotor blade segment and a second rotor blade segment along said longitudinal axis;
said first rotor blade segment having a first connecting region terminating in a first connecting end and said second rotor blade segment having a second connecting region terminating in a second connecting end;
said first and second connecting ends conjointly defining a partition interface transverse to said longitudinal axis;
a connecting assembly mutually connecting said first and second connecting regions at said partition interface to define a common segmentation region;
said rotor blade having a common outer contour of single curvature in said segmentation region formed by the connection of said first and second rotor blade segments;
said common outer contour being singly curved in said segmentation region to define only one curvature transverse to said longitudinal axis;
said partitioned rotor blade having a profile thickness and a profile depth which are constant in said segmentation region;
wherein said connecting assembly includes connecting devices in each of said first and second connecting regions to mutually connect said first and second rotor blade segments; and,
said segmentation region extends at least over said connecting devices along said longitudinal axis.
