The control system can begin to be installed on fighters from 2024
MOSCOW, July 28. /TASS/. The system for monitoring the technical condition of the aircraft in real time is planned to be installed on Su-57 fighters from 2024. This was announced to TASS at the MAKS-2021 Air Show held in Zhukovsky by a leading technologist of PJSC Sukhoi Company (part of the Rostec State Corporation UAC) Anton Mishachev.
"In 2022, we are planning flight tests on a prototype Su-57 product, and in 2024, we plan to install the system on a serial product. We have been working on it for the Su-57 fighter, but this system can be adopted for any aircraft, " he said.
He explained that the integrated monitoring system consists of two types of fiber-optic sensors-strain sensors and acoustic emission sensors. "The system allows you to collect data throughout the entire life cycle of the aircraft operation. Based on the information received, the remaining resource of the aircraft is calculated - how long it can still fly away," Mishachev said.
The sensors will be installed in critical areas of the aircraft. In the future, it is possible to install them on other models. "It is important to us what the aircraft consists of - the Su-57 is made using composite materials. For these materials, acoustic emission sensors will be used, which allow you to determine the destruction of the material by sound pulses-they read clicks. When the composites are destroyed, there are more and more sound pulses, which makes it possible to localize the zone where the destruction occurred. Also, deformation sensors will be used on the Su-57. They will be installed on the highly loaded elements of the aircraft, and it will be possible to judge the loads on this element by them, " the technologist noted.
Mishachev clarified that currently such a system is being tested and is not used during the operation of aircraft. "Thus, in operation, it is impossible to understand what loads were on the elements of the aircraft, how large they were in flights. All flights are different: in some cases, the plane flew smoothly and did not experience heavy loads, and in some it turned turns, as on MAX, and, of course, the loads on its units were significant. The resource of these aggregates depends on this, " he explained.
According to Mishachev, now specialists are engaged in optimizing the system and developing a block recorder that will be installed on the aircraft. The system will allow you to determine the state of individual zones of the aircraft and take into account the loads on them, which will make it possible to save on its maintenance. The project became one of the winners of the "Future of Aviation" competition organized by PJSC United Aircraft Corporation and was presented at MAKS-2021.
