Russian engine specialist Aviadvigatel is on track with development work on the PD-14 turbofan to power the Irkut MC-21 twinjet.
On-wing flight tests of the engine will begin early next year as planned, said Aviadvigatel director and chief designer Alexander Inozemtsev at an industry event in Moscow.
“We’ll mount the prototype on an Ilyushin Il-76 flying testbed and put it through a range of regimes to evaluate its performance,” he says.
“The certification programme schedule has been approved. Industry and the trade ministry have allocated necessary funds to complete it on time.”
Aviadvigatel is looking to deliver a first pair of PD-14 engines to Irkut for equipping the MC-21 test prototype in 2016.
“We plan to obtain a type certificate from [Russian airworthiness authority] ARMAK in 2017 and validate it under EASA [European Aviation Safety Agency] standards in the following year,” says Inozemtsev.
The PD-14 is being developed as a domestic alternative to the Pratt & Whitney PW1400G powerplant. United Engine chief Vladislav Masalov says the powerplant’s ground trials involve two variants with combustion chambers supplied by Russian and Ukrainian manufacturers.
“We’ll choose the one which proves to be better,” he adds.
