Replacement tip section for a rotor blade and method of replacing a rotor blade tip section

A replacement tip section for a rotor blade from which a legacy tip section was removed, the replacement tip section comprising:

• a blade tip portion having a first end and an opposing end, the blade tip portion configured to be attached to an intermediate section of the rotor blade after removal of the legacy tip section, the intermediate section having a connection feature at an end of the intermediate section to which the blade tip portion is attachable;
• a transition region configured to be attached to a forward end of the connection feature at an end of the intermediate section, the transition region configured to form a leading edge of the rotor blade and extending from the blade tip portion to form an opening into which the intermediate section is attached to the transition region and the blade tip portion, the transition region including a first end having a first airfoil that conforms to the intermediate section at the connection feature, and a second end having a second airfoil that conforms to the blade tip portion;
• wherein the connection feature includes a component previously configured to connect the intermediate section to a previously attached tip section;
• and
• wherein when the transition region is attached to the intermediate section, the component is modified to adapt the component to permit attachment of the replacement tip section.
