Scientific Description
Mission and objectives
The National Institute for Aerospace Research "Elie Carafoli" (INCAS) is the leading research establishment in aerospace sciences in Romania, with more than 60 years tradition in aerospace engineering, flow physics and applied aerodynamics, using state-of-the-art technologies and unique infrastructure of national strategic importance. INCAS has been involved in all major national aeronautical projects for civil and military areas.Reorganized in December 2008, INCAS has been repositioned as a research establishment, acting under public law as INCD, coordinated by ANCS - National Authority for Scientific Research. This transformation recovers the original position of INCAS as a successor of INCREST - National Institute for Scientific and Technological Creation before 1990 and follows almost 20 years of activity as a private company of the state.INCAS offers the usage of research infrastructures including trisonic and subsonic wind tunnels with state-of-the-art technology and outstanding competencies in major and niche areas for development at international scale.
