Abstract
A system for manufacturing a hollow multi-blade rotor includes a manifold having upper and lower manifold sections. The upper manifold section includes sealing ports that include sealing rings. The lower manifold section includes sealing port apertures that are configured to accept the sealing ports of the upper manifold section. The system further includes multiple pressure pads that are configured to collectively form a center hub area of the hollow multi-blade rotor within a mold during manufacturing of the hollow multi-blade rotor. Each pressure pad includes a hollow inner chamber and a hollow bladder extension. Each bladder extension guides an unsealed end of an inflatable bladder up through a sealing port aperture, thereby enabling the unsealed end of the inflatable bladder to be sealed between the sealing port aperture and the sealing ring of a sealing port when the upper manifold section is coupled to the lower manifold section.
