Turbine Blade/Disk Fabrication Investigation
Abstract
The report describes an investigation of blade/disk attachment methods for small gas turbine engines. The investigation included analytical and experimental evaluations of selected attachment methods potentially suitable for a 2-lb/sec axial flow turbine with 2500F turbine inlet temperature. A literature survey of attachments for small axial flow turbines yielded six candidate methods for further analytical study. The three most promising approaches were evaluated experimentally to determine the superior attachment technique. This attachment scheme was optimized by additional uniaxial experimental testing and final proof-testing by subjecting biaxial specimens to cyclic loads at the attachment design temperature.
