The first run of GE Aviation’s 2,000-hp-class advanced turboprop series, internally known as GE93, is on track for the fourth quarter of 2017, says business and general aviation and integrated systems VP Brad Mottier. ATP’s first reverse-flow combustor rig test has already been completed.

The engine has a 16:1 pressure ratio, almost twice that of Pratt & Whitney Canada’s highest-output PT6A-60 series engines, making for 10% more power at altitude and 20% better fuel efficiency. TBO will be improved to 4,000 hours.

Rated takeoff power will be between 850 shp and 1,650 shp. One variant will be rated at 1,240 shp, for instance, for Textron Aviation’s upcoming single-engine turboprop.

The new engine will be fitted with a single power lever control that integrates prop pitch and rpm, plus internal speed-, temperature- and torque-limiting functions. EASA certification of the system is expected this summer.

The key to the engine’s efficiency is a new 3-D aero centrifugal flow compressor, plus four axial flow compressor stages, all powered by a high-efficiency, bleed-air-cooled two-stage high-pressure turbine. A three-stage low-pressure turbine will power the gearbox and prop.

In addition to Textron’s new Pilatus challenger, the ATP has been selected by Turbine Air Corporation to power its new Turbine Venom, an FAA-approved, high-performance, kit-built speedster that is now in the final build phase.

The ATP is being designed, tested and produced in Europe, with 400 engineers working in Poland, Italy, Prague and at GE’s Global Research Center in Germany. A new $100 million H-series production center is expected to open in the Czech Republic in 2020. According to GE, the ATP program as a whole represents a $1 billion investment.

Mottier acknowledged that P&WC has earned a powerful franchise with its PT6A, broadening its appeal with turboprop, turboshaft, marine and industrial applications. He intends to follow suit with the ATP, offering the Canadian engine maker tough competition.
