GE tests 35% additive manufactured turboprop engine
GE tests 35% additive manufactured turboprop engine - November 2, 2016
The introduction:
Orlando, Florida – GE Aviation has completed testing a 35% additive manufactured demonstrator engine to validate 12 additive parts in its Advanced Turboprop (ATP) engine, which will power the new Cessna Denali single-engine turboprop aircraft. Additive components reduce the ATP's weight by 5% while contributing a 1% improvement in specific fuel consumption (SFC).
An additive CT7 technology demonstrator engine dubbed the "a-CT7" was designed, built, and tested in 18 months, reducing more than 900 conventionally manufactured parts to 16 additive manufactured parts. The ATP engine architecture is derived from the in-service CT7 engine, allowing for additive part commonality between the two engine programs.
The ATP will include more printed components than any production engine in aviation history with 35% of the turboprop's parts built via additive manufacturing. 855 conventionally manufactured parts will be reduced to 12 additive parts on the ATP, including: sumps, bearing housings, frames, exhaust case, combustor liner, heat exchangers and stationary flowpath components.
