Russian engine developer Aviadvigatel is likely to select component suppliers for its PD-14 powerplant through an international contest.
The firm is aiming to complete building of an engine demonstrator by March 2012, with a gas generator prototype already undergoing trials.
Chief designer Alexander Inozemtsev says: "Over the next year, we want to invite tenders to pick suppliers of key systems. Unless we receive competitive proposals from domestic firms, we'll have to turn to Western manufacturers."
Along with Pratt & Whitney's PW1000G, the PD-14 is designed to power United Aircraft's MS-21 twin-jet. But Aviadvigatel says there is a lack of suitable domestic technologies to meet its requirements.
"In particular, there are practically no competitive digital engine control solutions and our fuel pump systems are lagging behind [Western counterparts] in terms of operating time," admits Inozemtsev.
"We cannot use outdated technologies as this will lead to increasing engine weight and cost."
Inozemtsev believes there will be a new generation of engines in the market over the next five years. "To be competitive, the PD-14 should be cheaper by 15-22%," he says.
