Claim Text:
1. A system for manufacturing a turbine blade, the system comprising: an elongated flexible sleeve having a closed-off interior and positioned within a geometrical mold, wherein the elongated flexible sleeve is further positioned to have a desired geometry including a leading edge portion and a trailing edge portion, and wherein the geometrical mold further comprises a plurality of pegs in contact with the elongated flexible sleeve, the plurality of pegs being configured to shape the elongated flexible sleeve into the desired geometry; an infusing channel in fluid communication with the closed-off interior of the elongated flexible sleeve and configured to communicate a resinous material thereto at the trailing edge portion of the desired geometry; a vacuum channel in fluid communication with the closed-off interior of the elongated flexible sleeve and configured to vacuum seal the closed-off interior of the elongated flexible sleeve at the trailing edge portion of the desired geometry, such that the infusing channel is positioned directly adjacent to the vacuum channel; and a glass fiber layer positioned within the closed-off interior of the elongated flexible sleeve.
