The photographs of the Antonov An-148 regional jet made on June 11, 2009, when the first example of the aircraft built in Russia was rolled out from the assembly shop of the Voronezh plant VASO, give a clue on the amount of composite materials used in the aircraft. The aircraft was depicted when undergoing high-inside-pressure tests in the open air. Parts made of composite materials come in grey colors, in a contrast to airframe components made of aluminum, with yellow-green color appearance. Almost all construction materials in the An-148 airframe are Russian-made. The total weight of the composite parts is above 2,500kg, or about 12% of the aircraft’s empty weight. Wing’s leading and trailing edges and spoilers/interceptors are made of carbon plastics. Nosecone, fairings of the wing-to-fuselage attachment points and undercarriage fairings, as well as engine nacelle surfaces are made of glass plastics.
The Voronezh plant produces all of the named airframe parts using its own production facilities. When setting up the An-148 production line, VASO made special efforts to implement new, advanced technologies in parts manufacturing. In particular, the rudder and the moving stabilizer are integral, one-piece (non-disassembling) parts. Upper and lower outer surfaces, as well as the inner force-bearing structural members are formed in the autoclave in a single pass (heat treatment operation). This manufacturing method represents the most advanced technology in the field of composite parts production available. This and related technologies were proposed by Russian inventors. They were mastered and perfected at VASO. In the system of United Aircraft Corporation, VASO acts as the center of competence for composite materials. The plant supplies composite parts to Sukhoi Superjet 100 and prepares for production of similar parts for other aircraft types.
Within the framework of the advanced composite production effort at VASO, the plant formed a dedicated high-tech production unit that includes a workshop specializing on polymeric composite materials and a workshop producing composite subassemblies. The unit also includes a design and technologic department able to provide support for the whole set of technological steps starting from design of a part and preproduction preparations to streamlined production of airframe assemblies. The unit operates autonomously of other plant’s units.
VASO continues efforts on renovation of production tools. Among recent acquisitions are a machine tool for cutting “prepregs” (glass fiber after treatment with greases) and laser projectors. Next in line is a five-axis machine tool for streamlined production of semi-prepared parts.
Irkut Corporation (part of PJSC UAC of Rostec State Corporation) presented at the Eastern Economic Forum, held from 5 to 8 September 2022 in Vladivostok, the VR-stand of the SSJ-100 aircraft cabin, which will allow guests and forum participants to get acquainted with the interior of the aircraft in business version.
The United Aircraft Corporation (PJSC "UAC" as part of the State Corporation Rostec) will participate in the International Military-Technical Forum "Army-2022", which will be held from August 15 to 21.
The United Aircraft Corporation (PJSC UAC powered by Rostec) has successfully presented the MC-21-310 medium-range passenger aircraft, a new version of the business airliner based on the Superjet 100 under the Aurus brand and the Checkmate light tactical aircraft at the Dubai Airshow (United Arab Emirates). All three aircraft were presented abroad for the first time.
