Fedaravičius was elected an expert member of the Lithuanian Academy of Sciences; in 2011, he became a full member; and in 2021, he was named a member emeritus.

Academician A. Fedaravičius has published 273 articles and 4 monographs, and, together with co-authors, has authored 2 textbooks and 8 educational books for higher education institutions. He was the author of 128 inventions and patents (including 8 patents in the U.S., the U.K., Germany, and France). The main focus of the professor’s scientific work was the dynamics of mechanical, electromechanical, and mechatronic systems and their application to the development of new functional and technological mechanisms, machines, and equipment in the fields of specialized computing techniques, microelectronics, transportation engineering, defense, and other areas. Prof. A. Fedaravičius taught courses in theoretical mechanics (statics, kinematics, and dynamics), the dynamics of flying machines, the stability of flying machines, and the aerodynamics of vehicles to undergraduate and graduate students, as well as courses in analytical mechanics and the dynamics of defense systems to doctoral students. He supervised 11 doctoral candidates in the field of mechanical engineering within the technological sciences.

Prof. A. Fedaravičius served as a member of the Senates of Kaunas University of Technology (KTU) and the Lithuanian Military Academy, a member of the Founding Council of Kaunas Technical College, and a member of the Lithuanian Science Awards Commission (2005–2009), a member of the organizing committees of various international conferences, as well as a member of the editorial boards of the Lithuanian and international scientific journals *Mechanika*, *Vibroengineering*, “Problems of Mechatronics (Armament, Aviation, Safety Technology),” and the editorial boards of the periodical collection of scientific articles “Collection of Scientific Articles of the Baltic Association of Mechanical Engineering (BAME).” Prof. A. Fedaravičius also served as chairman of the board of the public institution “S. Darius and S. Girėnas Aerodrome” and as chairman of the Committee on the Integration of Science and the Defense Industry of the Lithuanian Confederation of Industrialists.

Founder and Director of the Institute of Defense Technology

In 2000, Prof. A. Fedaravičius founded the Institute of Defense Technology at Kaunas University of Technology (KTU), where he and his team carried out the development, research, and practical implementation of defense technologies. The technologies and equipment developed by the professor and the researchers under his leadership have been recognized by international NATO organizations. Laser rifle training simulators, mortar firing training equipment, and laser-based tactical training equipment for soldiers and combat units are just a few of the products of the professor and his colleagues’ scientific and engineering work, which are already widely used by defense institutions in our country and abroad. Prof. A. Fedaravičius’s most recent work was in the field of rocket technology development and research. Twelve devices developed by scientists at the Institute of Defense Technologies and deployed in Lithuanian and foreign defense structures have been assigned NATO NSN codes and included in the NATO Logistics Catalog.

Based on the equipment developed, riflemen training centers were established at: the Grand Hetman of Lithuania Jonušas Radvila Training Regiment, at the General Jonas Žemaitis Lithuanian Military Academy, at the Ministries of Justice of Lithuania and Latvia, at the State Border Guard Service Border Guard School, at the Lithuanian Riflemen’s Union training centers in Tauragė and Šiauliai, and at the General Povilas Plechavičius Cadet Lyceum; Mortar training equipment has been installed at the Division General Stasys Raštikis Lithuanian Army School. The Institute’s successful projects to develop and install laser rifle training simulators have saved millions of euros in state budget funds and significantly improved the quality and safety of the training process.

In the summer of 2011, researchers from the KTU Institute of Defense Technology successfully tested the “KTU GTI-95” and “KTU GTI-160” missile systems at the Juodkrantė test range. Speaking to BNS, Prof. A. Fedaravičius, director of the Institute of Defense Technologies, emphasized that rocket technology can be applied in fields ranging from the military to space. The professor lamented: “There is an inferiority complex in Lithuania, a lack of confidence in our scientific and engineering potential, which I certainly do not agree with. These successful tests alone prove it.”

The RT-400 training missile system, developed by researchers at the KTU Institute of Defense Technology, has been deployed with the Air Defense Battalion of the Air Force and used in the NATO air defense exercise “Amber Arrow.” Equipment developed by the Institute of Defense Technologies was awarded gold medals in the “Lithuanian Product of the Year” competition in 2000, 2005, 2007, 2010, 2013, 2014, and 2016. Despite these achievements and awards, in early 2017, as part of the reorganization of KTU, the Institute of Defense Technologies was integrated into the Faculty of Mechanical Engineering and Design. A. Fedaravičius continued his projects while working as a professor in the Department of Transportation Engineering at the Faculty of Mechanical Engineering and Design at KTU.

For his scientific research in the field of defense technology, Prof. A. Fedaravičius was awarded the Immanuel Kant Medal by the Baltic Association of Machine Manufacturers (2004), the “Knight of the Profession” award from the Lithuanian Confederation of Industrialists (2006), the “Badge of Honor” nomination from the Kaunas County Governor (2009), the 2nd-class Santaka Badge of Honor from the Kaunas City Municipality (2011), the “For Merit” Medal for Civilians from the National Defense System of the Republic of Lithuania (2016) ; Commendation from the Commander of the Lithuanian Air Force for cooperation in developing and implementing new engineering solutions that help improve the air defense readiness of the Lithuanian Air Force (2019); A letter of appreciation from the Commander of the Lithuanian Air Force for technical support and participation in the NATO air defense exercise “Tobruq Legacy 2020.” In 2022, Prof. A. Fedaravičius was awarded the Officer’s Cross of the Order of Grand Duke Gediminas by decree of the President of the Republic of Lithuania.

Hobbies

Prof. A. Fedaravičius’s hobbies included fiction, physical education and sports, and recreational aviation. He fulfilled his dream—he became a pilot in 2005 and, in 2007, founded the “Aero Pilot” association with his colleagues. Its goal is to bring together and utilize pilots’ experience and material resources to create a technical and material base for flying, aircraft maintenance, pilot training and skill development, and meaningful aviation-related leisure activities. In 2008, the association built an aircraft hangar, and in 2014, the accredited “Aero Pilot” pilot school began operations—at the S. Darius and S. Girėnas Aerodrome in Kaunas, the association began conducting pilot training.

Prof. A. Fedaravičius passed away on January 6, 2024, and was buried at Petrašiūnai Cemetery in Kaunas. His colleagues remember him as a man of great erudition and intelligence, yet at the same time simple and sincere, someone who knew how to listen and help, possessing strong will and patience, a tremendous sense of duty, and extraordinary diligence.
