Different control techniques will be studied: bump design, fluidic control devices, and DBD devices. The Project Topic will focus on experimental and numerical flow control investigations of different phenomena: the buffet on a laminar airfoil, the buffet on a turbulent supercritical airfoil, and the cross-flow instabilities on a swept wing. BUTERFLI is the acronym of BUffet and Transition delay control investigated within Europe-Russia cooperation for improved FLIght performances. Why FlyMiG.BUTERFLI is a project in response to the invitation to tender from European Commission FP7 within Call FP RTD-Russia.

Italian companies have also been upgrading many aircraft operated by Egypt and Syria. Many are undergoing updates of their avionics systems and being equipped with new cockpit displays and more modern missiles. Though the MiG-21 began to be replaced by the MiG-23 and MiG-27 during the 1970s and 1980s, several hundred of the more than 11,000 built are still in use in Russia, China, and several other countries. ![]() Later models were improved with more powerful and fuel efficient engines, radar, and ground attack capability increasing the aircraft's versatility and effectiveness. ![]() However, the MiG-21 long suffered from short range, small payload, and poor avionics suite. The original design was extremely light and maneuverable with exceptional reliability, sortie-rate, and low cost of operation. After experimenting with various wing configurations, the Mikoyan Gurevich design bureau chose a tailed delta configuration which eventually became the MiG-21. The Soviet Air Force requested a short-range interceptor to replace the MiG-17 and MiG-19 fighters in 1953. Truly one of the most remarkable aircraft of the Cold War period and perhaps the most successful aircraft in terms of number built since World War II, the MiG-21 has seen service with some 47 different nations throughout Asia, Africa, the Americas, and Eastern Europe since the late 1950s.
