2400 F Uncooled Turbine/Material Program. Volume II. Aerodynamic and Mechanical Design
Abstract
The report describes aerodynamic and mechanical design studies conducted to establish the preliminary design of a 2400F uncooled turbine component. The design activity was conducted concurrently with materials research to define the properties of IN-100 and AiResist 13 and to develop a high-temperature turbine material from intermetallic compositions of beryllide. The turbine mechanical design studies were based on estimates of IN-100 and beryllide material properties. Preliminary design studies were conducted to define a number of aerodynamic designs for efficiency comparisons and blade stress analyses, leading to selection of a candidate turbine design. Preliminary thermal and centrifugal stress analyses were conducted for each disk of the candidate turbine. The design established for the uncooled turbine was a three- stage axial flow turbine with equal work split among stages. The first- and second-stage blades and vanes were of beryllide material, and the third-stage rotor was to be integrally cast IN-100. Extensive thermal and stress analyses were conducted on first-stage turbine components to evaluate the feasibility of the uncooled turbine design. The design studies were terminated when it became apparent that the proposed beryllide turbine material lacked sufficient stress- rupture strength for rotor application and did not possess adequate ductility for either stator or rotor application.
