Perm developers presented to customers the unified PS-90A3u engine
April 2012 in Moscow there was a conference "Prospects of PS-90A engines development", during which one there was a presentation of PS-90A3u engine, which is designed for replacement of PS-90A series at certified aircraft — IL-96, Tu-204/214, IL-76TD-90 and their modification. JSC "Aviadvigatel", JSC "Perm Engine Company" with the participation of United Engine Corporation were organizers of the conference.

The conference was attended by almost all Russian airlines which use aircraft with PS-90A engines series: Russian presidential aircraft, "Aeroflot-RAL", "Red Wings", "Volga-Dnepr", "Transaero Airlines", "Aviastar-TU", "Polet".

At the conference's opening, managing director, chief designer of JSC "Aviadvigatel", Mr. Alexander Inozemtsev, noted that the decision on creation of the new modification in PS-90A engine series is dictated by need to propose to existing and potential partners of Perm motor builders the engines, created on the basis of up-to-date design solutions and technologies.

Deputy chief designer - chief designer of aviation engines of Perm design bureau, Mr. Alexander Semenov, told in details about PS-90A3u project and prospective of new modification. Certified in 2009, PS90A3u was created with aim to increase the exploitation parameters in compare with the level, reached at the basic PS-90A. The creators tried to reach changeability of PS-90A and PS-90A2 by developing this engine. However, even though in geometric and weight parameters, in conjoint parts the full changeability was reached, at the interface for PS-90A2 it was necessary to integrate deunification for Tu-204SM.

In 2011 at "Aviadvigatel", it was decided to return to idea of aircraft with PS-90 modernization with help of engine, which would have all technological advance of PS-90A2, but would not need any modification of aircraft. This engine gained an designation – PS-90A3u. Its primary difference in design from PS-90A is the using the fan's body frame of basic PS-90A engine with aim to decrease engine's weight and cost.

Chief designer of Perm design bureau expressed confidence that PS-90A3u will serve significantly longer over the wing, than basic PS-90A, and with reduced costs for repair. Airlines can can not only purchase new engines but also reequip existing PS-90A into PS-90A3 during overhaul.

While talking about the advantages of Ps-90A3u, chief designer highlighted the increased engine's average life before the repair. "This will allow companies to exploit aircraft more intensive by reducing the demurrage, caused by engine's replacing, will shorten number of repairs, made by enterprise-manufacturer, — highlighted Alexander Semenov. — Engine's downtime will be reduced from 50 to 22 months during the life cycle. Engine's reliability will be significantly increased, which will allow customers to minimize flight delay and preflight time".

For now JSC "Aviadvigatel" together with Perm Engine Company is holding the activity on the mastering of PS-90A2u mass production. "Many documents on PS-90A3u were released, design documentation is being released. We will try to install on one Tu-204 and one Il-76-TD-90 in the number of one PS-90A3u with aim of outmarch operation", — Alexander Semenov said.
