Russia has recently signed a contract that showcases its design plans for Russia’s first gas engine in the 75,000-pound thrust power class. The contract, endowed by the Russian government, was put into effect on January 19th, of this year. The engine will be used for military purposes and will be crafted by United Engine-Avadvigatel. They have until 2023 to deliver on their contract and the engine must contain top of the line features, like wide-chord composite fan blades and a new and improved fan case, as well as an improved cooling system.
The engine, named the PD-35-1, is designed to have a compressor ratio of 23 to 1, which is just a hair short of the GE9X engine currently in the Boeing Aviation 777X which runs at a ratio of 27 to 1. The PD-35-1 is set to be exposed to high heats that will melt most metal alloys. To prevent this from happening the PD-35-1 will be equipped with new cooling systems and new harder to melt materials.
The PD-35-1 is set to be the nations first engine to be able to handle over a 70,000-pound thrust. This new addition to Russia’s line-up will help them compete with other power houses like the USA and the UK.
Russia and China are teaming up under their CRAIC joint venture to help get the engine into a viable aircraft. Russia is also planning on implementing the engine in other aircrafts of theirs like airlifters, taker and to eventually replace the Antonov An-124 indefinitely.
