In a move to increase the number of locally-made components on the Superjet 100 (SSJ100) Russian regional jet, Technodinamika Holding, which is part of the Rostec hi-tech conglomerate, has been contracted to develop and deliver by 2023 the first pilot batch of new landing gear installations for aircraft manufacturer Sukhoi Civil Co’s new version of the Superjet 100, which it refers to as the SSJ-New. The new gear is designed to replace the SSJ100’s main and nose gear that is currently supplied by Safran of France.
The latest development is currently underway at the Samara-based Aviaagregat, which has now completed the conceptual design first stage, including the gear struts, the nose wheel steering and retraction deployment mechanism.
Once the engineering design stage is complete, Technodinamika will start work on the design documentation as part of a research and development framework. The first delivery of the new gear for static testing on the aircraft is scheduled for early 2021 and, following that, Technodinamika plans to supply several gear kits for the SSJ-New flight test prototypes.
The brainchild of Russia’s industry and trade ministry, the SSJ-New programme is a modification of the original SSJ-100 with the replacement of imported components and systems with Russian-made alternatives. The project aims to increase to 50-60 per cent the aircraft’s share of locally made components and systems. Along with phasing out the imported parts, engineers are also working on upgrading the systems’ reliability, whilst also improving levels of safety, comfort and continued airworthiness.
The SSJ-New variant is reportedly scheduled to materialise by 2024.
Technodinamika Holding is part of Russia’s state-run industry giant Rostec and specialises in the development, production and aftersales support of aircraft systems and components. It is also developing fire-protection system for the russified version of SSJ100.
