Small gas turbine engine manufacturers, with Armed Services support, are utilizing advanced manufacturing technology programs to incorporate net shaped components into both the current and the next generation of small high performance gas turbine engines. A coordinated program is underway to provide near-net shaped components which will minimize machining costs, save critical materials, and in some cases provide increased component capabilities. These programs include isothermal forging of titanium, casting of titanium, HIP’ed titanium powder metal techniques, diffusion bonded dual property approaches, and a diffuser case fabrication process. The manufacturing technologies presented in this paper are currently being targeted for small gas turbine engines.
