However, officials of Ilyushin and Tupolev design bureaus said retrofitting of warplanes with the new engines was premature.
Today, the Ilyushin airplanes operate engines PS-90 produced by OJSC Perm Motor Plant. "These engines have proved themselves perfectly, we’re not about to change them", explained the Ilyushin’s expert.
According to the Tupolev's spokesman, the changeover from PS-90A to PD-14 engines is unfeasible due to immense financial expenses of the aircraft refitting, certification and replacement of production facilities.Nonetheless, he added that if the ‘perfected’ PD-14 engine enters international market, the leading American and European engine manufacturers would bend every effort to hinder its certification.
PD-14 is the basic model in the family of new-generation turbofan bypass aircraft engines with unified gas generator. It is designed for MS-21-type civil short-haul airplanes.
According to ODK-Aviadvigatel, the PD-family engines can be used on other types of aircraft for further improvement of their cargo-carrying and economic characteristics: extension of flight range, decrease of fuel consumption and carriage cost. It is the first new domestic aircraft engine over the last two decades, emphasized the manufacturer’s spokesman.
