METHOD FOR BALANCING SET OF BLADES Russian patent published in 2022 - IPC G01M1/12 

FIELD: aviation.

SUBSTANCE: present invention relates to a method for balancing an aircraft engine disk feathered with blades and, more specifically, to a method for balancing a set of blades designed to be mounted on a non-feathered aircraft engine disk. The invention relates to a method for balancing a set of blades (5) to be mounted on non-feathered disk (7) of an aircraft engine, containing a certain number of numbered sockets (a_i) that hold the same number of blades that may have mass spread, while the method contains stages, at which: blades (5) are sorted in a monotonous order by their mass (m_i), forming an ordered set of blades; this ordered set of blades is divided in a balanced manner into four petals, which include first large petal (GL1), second large petal (GL2), first small petal (PL1) and second small petal (PL2), while in each petal, blades are sorted in the current order of placement; four petals (GL1, GL2, PL1, PL2) are placed on non-feathered disk (7) so that the current order of placement of blades corresponds to numbered sockets on the non-feathered disk.

EFFECT: minimization of calculation time, taking into account limitations associated with the centrifugal force and the imbalance of non-feathered disks, limitation of the deformation of the disk, and increase in the service life of the blade.
