Korea Aerospace Industries (KAI) and Korea Aerospace Research Institute (KARI) jointly develop a vibration source (blade), the next-generation core technology for helicopters. ) Start the active control device SW development in earnest.

On the 14th, KAI and KARI signed an agreement with the Defense Technology Promotion Research Institute (hereinafter referred to as Kukkiyeon) for the ‘development of active control device SW for vibration source for medium-sized helicopters, which is a core technology R&D project to be started in 2021’.

The vibration source active control device SW technology is a technology that automatically controls helicopter vibrations by adjusting the angle of the rotor blades.

This project is an industry-university-research joint development project, and KAI, the host company, and KARI, the partner organization, participate in a consortium form, and Seoul National University, Chungnam National University, and Gyeongsang National University cooperate.

In this project, KAI plans to develop a vibration source active control device SW and verification device, undergo a reliability test, and apply it to the final Surion prototype to prove its performance.

The development cost is about KRW 12.3 billion and the development period is 48 months from December ’21 to December ’25.

KAI and KARI have successfully completed the development of AVCS (Active Vibration Control System) SW that reduces vibrations in the fuselage.

KAI is promoting the evolution of existing helicopters such as Surion performance improvement, Manned Unmanned Teaming (MUM-T), and the development of next-generation mobile helicopters, as well as core technology development for future helicopters.

When the R&D of the vibration source active control system is successfully completed and mounted on a domestic medium-sized helicopter, it will be the first case in the world applied to an operational aircraft.

In October, KAI signed a contract with the Defense Acquisition Program Administration for the ‘helicopter-unmanned aerial vehicle interworking system business’, a ’21 rapid pilot acquisition project’, and started to develop MUM-T technology that enables collaboration between helicopter platforms and unmanned platforms.

In addition, the localization of the helicopter power transmission system, which relied only on foreign technology, is in progress through participation in the R&D project of the Ministry of Trade, Industry and Energy.

KAI plans to apply it to UAM and the medium-sized helicopter business to be developed in the future through continuous research and development of helicopter core technology.

A KAI official said, “We are continuing research on future helicopter technology through cooperation with the government and domestic industry-academia-research institutes.” “We will break free from dependence on helicopter technology overseas and contribute to the development of the helicopter industry by strengthening military power as well as strengthening the competitiveness of domestic helicopters. will,” he said.
