The PD-35 engine demonstrator has become the basis for a new line of domestic high-thrust turbojet engines. This is the first step towards creating Russian wide-body airliners and heavy transport aircraft capable of replacing foreign counterparts.
New Era of Russian Engine Building
The development of the PD-35 began in 2016 as a response to the aging Soviet D-18T engines and dependence on imports. The program brought together leading enterprises of the United Engine Corporation (UEC, part of the Rostec Group), "UEC-Perm Motors" and VIAM. The first stage of gas generator testing took place in 2022, and the technology demonstrator in 2024.
The PD-35 is created on a modular principle, using composite materials and additive technologies. The fan diameter is 3.1 m, and the carbon fiber blades reduced the weight by 600 kg. The new FADEC control system provides digital control and real-time diagnostics.
Testing and Record Characteristics
The demonstrator tests were carried out on the OS-5 open stand near Perm. More than 20 innovations were tested - from heat-resistant alloys to new bearings. The temperature in the turbine reaches 2000 K, and cooling is implemented through internal channels, forming a protective "film".
Platform for Decades to Come
The PD-35 will become the basis for a whole line of engines with a thrust of 24 to 50 tons. It will form the basis of the PD-26 - for a promising transport aircraft with a payload capacity of 100 tons, as well as a new wide-body airliner.
As soon as the engine is ready, Russia will be able to start developing its own long-range aircraft. Previously, the CR929 project with China was suspended, but the parties do not rule out cooperation in the supply of components.
Significance for Domestic Aviation
The competencies gained during the creation of the MC-21, including the composite wing and the PD-35 gas generator, will give Russia technological independence.
The PD-35 opens the way to a new generation of engines - from the Il-100 to future modifications of the MC-21-500 and MC-21-600. For the first time in three decades, Russia is ready to enter the wide-body aircraft market, controlling the key technology - the engine.
As a reminder, the United Engine Corporation is working on PD-8 engines for the Superjet, PD-14 for the MC-21 and the promising PD-35, for which there is no aircraft yet.
