Current scientific knowledge related to miniature turbochargers and gas generators is still improving. Various concepts are being tested seeking performance enhancement. Variable Area Nozzle (VAN) system is one of them. It aims to optimize effective area nozzle controlling both: turbine entry temperature and mass flow rate. The article presents different variable geometry concepts and recent research on VAN applied to a miniature gas turbine at Warsaw University of Technology. VAN concept and related phenomena are discussed.
