Technodinamika Holding  carried out preliminary testing of prototypes of the fire-protection system developed jointly with Curtis-Wright Controls. The test results fully confirmed the stated system specifications. Representatives of the Holding estimate that the system will pass certification tests as part of aircraft by late 2017, and its batch manufacturing will commence soon thereafter.

FIRE-PROTECTION SYSTEM

The characteristics of the modern FPS surpass those of its counterparts available on the Russian market. The system's mass was reduced by 15% through the use of composite materials and design optimization. The system, developed by Technodinamika, features enhanced reliability and increased service life, reduced operation costs, and high degree of standardization. The estimated time from commissioning until disposal amounts to 80,000 flying hours or 60,000 flights. The service life is 30 years. The design and operation algorithm of the system ensure protection against false responses, both at the level of the sensory devices and the processor.
The system components were tested at the Molniya enterprise in Ufa, where the control unit was tested, and at the Respirator enterprise located near Moscow, where the fire extinguishing subsystem was tested. The subsystems were subjected to a strength test, a technical specifications compliance test, and a test for immunity to external influencing factors (including climatic tests).

The system, which has been under development since 2013, is intended for МS-21, but in the future it can be used for Sukhoi Superjet and other aircraft, including wide-body and transport types, by virtue of its module architecture. "The number of sensory devices and fire extinguishers may vary, but the control unit is universal," explains Victor Nikolenko, the Director of the Technodinamika Engineering Center. Besides, standardization of the system components for various types of aircraft leads to greater seriation and, consequently, reduced cost for the buyers." A state-of-the-art helicopter FPS can be developed on the basis of the developed standardized aircraft system, retaining the major competitive strengths. The system will also be offered to the world's aircraft producers.

The Holding played a leading role in developing the system. The development was spearheaded by the Technodinamika Engineering Center, while Curtis-Wright Controls was responsible for the system's certification in compliance with the international standards.

"Our number one priority is to bring new models of competitive products into the market," points out Maxim Kuzyuk, CEO of Technodinamika. "Such products will become the major growth drivers for the Holding, both in Russia and abroad." Under the development strategy, by 2020 the Holding aims to become a global supplier of 12 aviation systems, including alighting gears; electric, safety, and life support systems for aircraft; power units; as well as hydraulic and fuel systems.
