Abstract
The invention belongs to the technical field of molding of a composite material rotor blade, and provides a method for positioning and assembling the composite material rotor blade of a C-shaped beamstructure. The method includes the steps of paving a lower mold skin (2) and an upper mold skin (6) on a lower press mold (1) and an upper press mold (7) respectively; mounting a lower mold girder (3)on the lower mold skin at first, and positioning and calibrating the lower mold girder (3) by using chordwise profile outline templates (8) to ensure that the girder is accurate in placement positionand direction; mounting a blade foam core (4) on the lower mold girder (3), and then mounting an upper mold girder (5); and assembling the upper press mold and the lower press mold which are paved with the skins, and carrying out heating, pressurizing and curing. According to the method for positioning and assembling the composite material rotor blade of the C-shaped beam structure, the chordwiseprofile outline templates at different positions are arranged, accurate and rapid assembly of parts in the composite material blade is realized, and the product assembly efficiency is improved. By means of the method for positioning and assembling the composite material rotor blade of the C-shaped beam structure, the mold pressing quality of the composite material rotor blade of the C-shaped beamstructure is improved, and the product qualification rate is improved.
