Rotor flanges of turbine engines

摘要

The rim of a turbine disc is provided with a circular collar upon which is engaged the heel of an annular flange having a U-shaped cross section with unequal sectors, i.e., a principal piece forming a circlip and a smaller piece forming a key which completes the flange following the installation of the circlip; the key is retained in its position by cuts of the ends of said key.
