GE Aviation’s Advanced Turboprop engine, the first clean-sheet turboprop engine to hit the Business and General Aviation (BGA) market in more than 30 years, successfully completed its first engine test run at GE Aviation’s facility in Prague, Czech Republic.
“Running the Advanced Turboprop engine this year was our biggest and most important goal,” said Brad Mottier, vice president and general manager of GE Aviation’s BGA and Integrated Systems organization. “This milestone comes as a result of two years of tremendous effort by a worldwide team. We’re developing a real catalyst for the BGA market and we’re executing on plan. The integration of proven technologies has expedited the design, development and certification cycle of the engine.”
The Advanced Turboprop engine will begin certification testing in 2018. The engine will power Textron Aviation’s new Cessna Denali, which is expected to fly in late 2018. By the time the Denali enters into service, the engine will have completed more than 2000 hours of testing.
“The continued testing will generate valuable data from the engine and validate the aerodynamics, mechanics, and aerothermal systems,” said Paul Corkery, general manager for GE Aviation Turboprops. “With the engine run and most of the individual component testing completed, early indications show that we will meet or exceed all the performance numbers we have quoted for the engine.”
The new 1,240 SHP-rated Advanced Turboprop engine is in the family of turboprop engines aimed at BGA aircraft in the 1,000-1,600 SHP range. With 79 new technologies introduced, the engine offers a portfolio of advanced technology, as well as unparalleled performance and efficiency.
The Advanced Turboprop engine features an industry-best 16:1 overall pressure ratio, enabling the engine to achieve as much as 20 percent lower fuel burn and 10 percent higher cruise power compared to competitor offerings in the same size class. At 4,000 hours, it offers 33 percent more time between overhaul than its leading competitor.
When installed on the Denali, these engine efficiencies allow for a larger cabin experience with a comfortable 6000-foot cabin altitude at a 30,000-foot cruising altitude, as well as class-leading, low cost of operation compared to smaller aircraft in the category.
