| 发明名称 | Profile of a rotor blade and rotor blade of a wind power plant | ||
| 摘要 | The profile (1-4) of a rotor blade (5) of a wind power plant is characterized in that the main camber line runs beneath the chord at least in sections in the direction of the pressure side (8). The profile is further characterized in that the profile (1-4) has a relative profile thickness of greater than 45% with a position of maximum thickness of less than 50%, wherein a lift coefficient (ca) of greater than 0.9, particularly greater than 1.4 is achieved in turbulent flow. | ||

| 主权项 | 1. Profile (1-4) of a rotor blade (5) of a wind power plant, the rotor blade comprising: an upper side (suction side) (7), and a lower side (pressure side) (8) with a main camber line (21, 25) and a chord (18) between a leading edge (10) and a trailing edge (11) of the profile (1-4), wherein the main camber line (21, 25) runs beneath the chord (18) at least in sections in a direction of the pressure side (8), wherein the profile (1-4) has a relative profile thickness of greater than or equal to 55% of a length of the chord (18), wherein a position of maximum thickness is at less than 35% of the length of the chord (18) from a nose of the rotor blade, wherein the main camber line (21, 25) is disposed completely beneath the chord (18) in a section between 2% to 60% of the profile depth of the profile (1-4). | ||
