Mounting structure of aero-engine rotor blade

The invention belongs to the technical field of aero-engine rotor blade installation and design, and particularly relates to an aero-engine rotor blade installation structure which comprises a rotor wheel disc with an annular mortise in the outer edge and an installation notch in the side wall. The mounting notch is communicated with the annular mortise; a plurality of rotor blades including: a blade body; the upper side wall surface of the edge plate is connected with the root part of the blade body, and the connecting part of the edge plate and the root part of the blade body is rounded; the front end part and the rear end part of the two side edges of the margin plate are planes parallel to the axis of the rotor wheel disc, and the planes of the front end part and the rear end part are in curved surface transition and are S-shaped; the tenon is connected to the lower side wall surface of the margin plate; the tenons are clamped into the annular mortises sequentially through the installation notches, and th
