Among the innovations to be presented by the Holding, the most anticipated is the electrical ground taxiing system for landing gear developed by a consortium of Russian developers as part of a fully electric aircraft concept. This is the first development of such a type in Russia. The system comprises an electric drive built into the landing gear, which enables movement over the apron without using the main engines, including moving backwards.
The inert gas system will be presented at MAKS for the first time. Its task is to enhance aircraft safety. Filling the above-fuel space that forms in the fuel tank with fuel depletion with atmospheric air may result in an explosion. The developed system pumps atmospheric air through the membrane module by separating the fraction with reduced oxygen content. This fraction fills the above-fuel space, thereby increasing aircraft safety. A feature of this system is that it is a completely Russian development.
The variable frequency alternator is one of the Holding's most recent developments. This new-generation alternator has no equivalents in the Russian market. It will be at the same level as the production of global leaders Thales and UTC. It is developed for the MS-21, and even now its design efficiency is 8% higher, its weight is 25% lower, and furthermore it is cheaper and more reliable than any Russian analogue used. This new development will become the base for the main line of alternators; so, 60-kW alternators will find application in Russian helicopters, including advanced ones, for instance, the Russian-Chinese project. The 40-kW alternator intended for use on IL-112V aircraft will be included in this line as well.
The Holding will also present a new auxiliary power unit APU-90/120. This new auxiliary power unit for narrow-body aircraft has no analogues in the Russian market. Technodinamika designers have managed to increase significantly the service life and reliability, and decrease weight and dimensions. The main design feature of the APU-90/120 is the use of a 2-stage centrifugal compressor. Implementation of innovative design solutions in the new auxiliary power unit will make it possible to reduce its operating costs.
The latest fire protection system being developed in cooperation with the American company Curtiss-Wright-Controls has attracted special attention at Russian and international exhibitions in 2015. The most important system feature is fast activation and reaction speed that ensures aircraft passenger safety. Furthermore, it will have the highest reliability due to false activation protection, as well as being adaptable for various aircraft types. The system's modular architecture will provide lower operating costs, a significant service life increase, as well as maximum standardization of components between various aircraft types.
Another vital development presented at the MAKS will be the landing gear for the Ка-62 helicopter. A feature of the Ka-62 helicopter landing gear design is a shock absorber and retraction actuator combined in a single unit. The combined retraction actuator ensures shock absorption of loads in landing, retraction and extension of landing gears and when holding in the corresponding positions. It has small overall dimensions and makes it possible to satisfy the requirements for helicopter landing at high vertical speeds and to use the helicopter for offshore transportation.
