Modern high-tech production of aircraft gas turbine engines relies on the active implementation of artificial intelligence (AI) and machine vision systems. Design and manufacturing processes increasingly incorporate digital tools for big data analysis, process optimization, and enhanced quality control throughout the product lifecycle.
Predictive analytics solutions accelerate data processing, optimize engineering decisions, and support R&D and design teams. AI assistants are being developed for process engineers, quality control specialists, and engineers working with TRIZ methodology, while data security requirements for AI applications are being established. These initiatives align with the industry’s ongoing digital transformation.
TRIZ (Theory of Inventive Problem Solving), developed by Genrich Altshuller in the USSR in the mid-20th century, is based on systematic analysis of patents and engineering solutions to identify common approaches and patterns in technical system development.
TRIZ provides tools for identifying and formalizing technical contradictions, algorithms for generating new ideas, and methods for forecasting technology evolution. In the aviation industry, TRIZ is used to optimize designs and find non-trivial solutions for complex systems such as aircraft engines.
Additive manufacturing has become a key area of modernization at United Engine Corporation (UEC) facilities. For example, the PD-14 engine features Russia’s first certified hot-section component produced by 3D printing-a combustor swirl vane. Serial engine designs utilize domestically developed alloys tailored for aerospace applications. 3D printing technology and advanced materials meet stringent strength and heat resistance requirements, as confirmed by flight tests on MC-21-310 prototype aircraft.
Both prototype and production engine components are manufactured at the UEC Additive Technology Center (ATC). The ATC implements innovative technologies for complex geometries, develops unified industry standards for additive manufacturing, and advances quality control methods. Industrial 3D printing significantly reduces R&D timelines and accelerates component production. Additive methods also enable the creation of lightweight, intricate parts.
The ATC employs selective laser melting of metal powders, direct laser metal deposition, laser sintering of polymers, material extrusion, and stereolithography. These techniques allow for the fabrication of parts with internal cavities and complex shapes unattainable by conventional machining. The center has mastered over 14 new material types, including aluminum, nickel, cobalt-based superalloys, and titanium alloys, expanding 3D printer capabilities and fostering multi-sector partnerships.
The ATC’s equipment fleet exceeds 120 units, including production systems and laboratory instruments. Its accredited laboratory features a high-precision X-ray tomograph with up to 4-micron resolution, enabling comprehensive quality control of manufactured components.
Experience gained from the PD-14 program was leveraged in developing the PD-35 demonstrator engine. Over 2,300 components were designed and manufactured for this high-thrust turbofan, including high-pressure compressor elements, actuators, and low-pressure turbine blades.
At UEC-Saturn, PD-8 engine components are also produced using additive methods. The PD-8’s production design incorporates more than ten synthesized parts, while over 200 components were designed and more than 1,000 manufactured during R&D.
Product compliance is ensured through selective laser melting with mandatory optical and X-ray inspection. 3D printing utilizes domestic powder alloys based on cobalt, nickel, titanium, and stainless steel, developed by UEC-Saturn specialists. The company has advanced additive manufacturing for over a decade. In 2024 alone, more than 7,000 gas turbine engine parts for aviation and power generation were produced using layer-by-layer synthesis.
UEC-Aviadvigatel in Perm is developing the advanced PD-26 heavy engine, rated at approximately 57,300 lbf (255 kN) thrust. According to First Deputy Prime Minister Denis Manturov, the PD-26 is based on the PD-35 demonstrator’s gas generator, which completed test bench trials in 2024. The new engine is intended for both military transport and civil aviation, including future aircraft with a maximum takeoff weight of around 220,000 lb (100 metric tons).
Since the PD-26 is built on the PD-35 gas generator platform and utilizes the same core technologies, it is expected to incorporate the full suite of advanced materials and innovative processes developed for the PD-35. This includes composite fan blades, heat-resistant superalloys, advanced turbine blade cooling techniques, and additive manufacturing. Strategically, a unified gas generator platform enables the creation of a family of powerful, standardized propulsion systems.
The fifth-generation engine family—PD-8, PD-14, PD-26, and PD-35—forms the foundation of Russia’s technological independence in aircraft engine manufacturing. These models effectively address the full range of civil and military aviation needs, from regional jets to heavy cargo and wide-body airliners. Government support, digital technology adoption, and additive manufacturing development are opening new horizons for Russian aerospace engineering and ensuring global competitiveness.
