Modifying rotor blade length and installing cuff for aircraft
A recently granted patent (Publication Number: US11919627B2) discloses a method for modifying a rotor blade by adjusting the root portion of the inboard section to change the length of the blade and installing a cuff to connect the blade to an aircraft. The method involves removing the root portion to shorten the blade length and replacing the original cuff with a new cuff designed for the specific aircraft.
Additionally, the method includes the installation of a blade extender, which acts as the cuff and connects the rotor blade to the aircraft. This process may involve removing the original cuff by disconnecting it from the mounting hole in the spar and replacing it with the blade extender. The blade extender is positioned around the blade root, with an opening at the inboard end that is smaller than the blade root, ensuring a secure connection between the blade and the aircraft. These modifications allow for customization and optimization of rotor blades for different aircraft configurations, enhancing overall performance and efficiency.
