FIELD: transport; aerotechnics.
SUBSTANCE: support for installation of main reduction gear with rotor hull body with cylindrical hull element, basement, rib reinforcement, and units for attachment of main reduction gear. Basement has flat-topped in plane with essentially L-shaped cross-section. Vertical basement seat is equipped with additional plate. Cylindrical hull element between free ends of flat-topped basement changes shape for flat U-form element with convex part turned down from plane within which units for attachment of main reduction gear are located along perimeter of cylindrical hull element. Additional plate in plane approximately follows basement contours, but it is closed over perimeter and has essentially T-shaped cross-section. Above-mentioned units for attachment of main reduction gear are made as bosses of cylindrical hull element with shaped cylindrical orifices.
EFFECT: optimal rotor load transfer, taking of concentrated operation loads.
