SUPPORT FOR MOUNTING MAIN GEAR BOX WITH ROTOR Russian patent published in 2012 - IPC B64C27/00 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering, particularly, to design of helicopter main gear box with rotor. Proposed support is made up of structural body consisting of "П"-like base in plan with cylindrical structural element jointed to flat plate incorporating horse-shoe-shaped element that flat plate shape in plan approximates to base horseshoe shape but in mirror reflection. Base and flat plate are jointed together by free ends of their "П"-shape bodies. Internal parameters of cylindrical structural body and horseshoe-like element form closed loop, profiled cross section to attachment of sealing element thereto. Main gear box is attached on base assemblies arranged along the edges of cylindrical structural element. Closed loop configuration approximately reproduces surface contour in main gear box cross-section at the point of connection therewith. Support is secured by base and flat plate to fuselage frame. Note here that base attachment assemblies are arranged mainly on medium flange of the base "П"-like shape while flat attachments are arranged along its outer edges.

EFFECT: redistribution of loads, support integrated into fuselage frame.
