The invention provides a rudder blade, a manufacturing method thereof, a segment thereof, and a segment for a rudder blade or for an apparatus for improving propulsion. In order to provide a rudder blade, which has a low level of weight, is easier and more inexpensive to manufacture, that meets the various strength and stability requirements for various rudder-blade sections, which can be at leastpartly manufactured in an automated manner and for which the manufacturing of irregular surfaces, in particular, the leading edge, is made easier, a rudder blade (100) is proposed, which has a modular structure, wherein the rudder blade comprises at least two prefabricated rudder-blade segments (10, 11, 12, 13) and is composed of the at least two prefabricated rudder-blade segments (10, 11, 12, 13). 舵叶及其制造方法、其区段、舵叶或改进推进设备的区段。为了提供一舵叶，该舵叶具有低重量水平，制造起来更容易且更便宜，该舵叶满足针对不同舵叶部段的不同强度和稳定性要求，可以至少部分地以自动化方式制造该舵叶，并且对于该舵叶，使得更容易制造不规则表面特别是前缘，提出了舵叶(100)，该舵叶具有模块化结构，其中舵叶包括至少两个预制的舵叶区段(10、11、12、13)并且由至少两个预制的舵叶区段(10、11、12、13)组成。
