This program to develop a process for a low-cost productioninstallation of urethane leading edge guards for rotor blades was to consist of three tasks as follows Task I - Manufacturing Process Identification. a Conduct a survey of manufacturers and literature for suitable erosion guard materials. b Determine flow, bonding, and temperature characteristics of the selected material. c Demonstrate the feasibility of the process of molding a boot on a 4-foot section of blade. Task II - Tool Design and Fabrication. From the results obtained in the molding phase of Task I, refine the tool concept and design and fabricate a tool to mold an erosion boot on a full-length blade. Task III - Fabrication Process Demonstration. Using the experience gained in Task I and the tool fabricated in Task II, form, bond, and inspect four full-scale leading edge erosion boots. Analyze and compare costs to current production process and prepare manufacturing work instructions.
