Disclosed is a rudder structure. According to one aspect of the present invention, the rudder structure includes: a rudder stock formed to be longitudinally extended and transferring steering force thereto; a rudder blade coupled to a lower end portion of the rudder stock so as to be rotatable about the central axis of the rudder stock; a rudder bulb installed to protrude from the rudder blade in a position of facing a propeller of the rudder blade; and a piezoelectric element installed on the rudder bulb so as to convert mechanical stress applied to the rudder bulb into electric energy.

    러더 구조체가 개시된다. 본 발명의 일 측면에 따른 러더 구조체는 종방향으로 연장되게 형성되어 조타력을 전달하는 러더 스톡(rudder stock), 러더 스톡의 중심축을 중심으로 회전 가능하도록 러더 스톡의 하단부에 결합되는 러더 블레이드(rudder blade), 러더 블레이드 중 프로펠러와 대향되는 위치에 러더 블레이드로부터 돌출되게 설치되는 러더 벌브(rudder bulb) 및 러더 벌브에 가해지는 기계적 응력을 전기에너지로 변환시키도록 러더 벌브에 설치되는 압전소자를 포함한다.
