The present invention relates to a propeller attaching a wing to a blade tip part in which the rotating speed of the wing is fast, unlike a conventional propeller. In a blade tip propeller, in order to reduce the rotation friction of the wing (102) formed in a blade scape (104) around a blade scape hub (106) and prevent the flutter or vibration of the wing, the outer side of the wing (102) is matched with an arc of an outer rotary side and the inner side of the wing (102) is matched with an arc of an inner rotary side. An angle of the outer arc is equal to an angle of the inner arc around the center of a rotating shaft. Accordingly, the present invention can produce a stronger thrust.
본 발명은 기존 프로펠러와는 다르게 날개의 회전속도가 빠른 깃단(Blade tip)부분에 날개를 부착한 회전날개로, 깃대중심부(106)를 중심으로 깃대(104)에 형성된 날개(102)의 회전마찰을 줄이고, 날개의 플러터나 진동을 막기 위해 날개(102)의 바깥쪽 면은 바깥 회전면의 호에 맞추고, 날개(102)의 안쪽면은 안쪽 회전면의 호에 맞추며, 바깥쪽 호의 각도와 안쪽 호의 각도를 회전축의 중심을 중심으로 하여 같게 한 것을 특징으로 하는 깃단회전날개이다.
