18. Aeronautics in Lithuania –Education Research and IndustryNEW PROJECTS – LIGHT AIRPLANES Some of the new experimental airplanes designed at Antanas Gustaitis’ Aviation Institute : We have a possibility to use modern CAD-CAE computer software (Mechanical Desktop, CATIA, ANSYS etc.) and powerful Pentium 4 and RS6000 computers.

19. Aeronautics in Lithuania –Education Research and IndustryMODERN LIGHT AIRPLANES FROM LITHUANIA - LAK-17 Prienai Sportine Aviacija company has designed one of the most advanced lightweight airplanes – LAK-17. It is 15-18m FAI class glider of carbonfibre structure and modern laminar wing section developed in Lithuania. Its modification LAK-19 (standard FAI class glider) waspresented in 2001.

20. Aeronautics in Lithuania –Education Research and IndustryMODERN LIGHT AIRPLANES FROM LITHUANIA – LAK-X Helisota Ltd from Kaunas is testing its light JAR-VLA class trainer LAK-X. It is a modern composite two place airplane with outstanding flight characteristics and low fuel consumption. There are two main modifications of the airplane with choice of two engines (95 or 125 hp).

21. Aeronautics in Lithuania –Education Research and IndustryNEW PROJECTS – UL SYSTEM FOR TRAINING PRIMARY TRAINING SYSTEM USING UL AIRPLANES UL trainer Profession Developed at AGAI Made in Lithuania Primary glider UL training glider Sport Hobby The initial flight training system using ultralight aircrafts (gliders and airplanes) is designated to promote professional, sport or hobby pilot’s career.
