Research project IPROP: Ionic PROPulsion in Atmosphere

The Chair of Flight Mechanics and Control has officially commenced its work on the international  IPROP project, focused on innovative Ion-Wind-Thruster (IWT) research. The project aims to advance the understanding and applicability of IWT for high-altitude platform applications, potentially revolutionizing their deployment in various fields, from communication to environmental monitoring. By combining experimental aerodynamic research with advanced control strategies, the Chair of Flight Mechanics and Control seeks to contribute to this ambitious goal.

Ion-Wind-Thruster operate on the principle of electrohydrodynamics, where an electric field generates a flow of ions in a fluid medium, typically air. This process begins with ionization, where a high-voltage electric field created by an emitter electrode ionizes nearby air molecules. These charged particles are then accelerated toward a collector electrode of opposite polarity, transferring momentum to neutral air molecules in the process. This momentum transfer generates a thrust force, known as ionic wind, which can be used for propulsion or flow control without moving parts, making IWTs highly efficient and silent in operation.

High-altitude platforms operate in high altitude, thus low-density atmospheric conditions. To replicate and study the IWT under these realistic conditions, experimental investigations require specialized facilities. Our chair possesses a unique vacuum wind tunnel, which allows for precise testing of IWT performance under low-density environments, advancing the development of this innovative technology.
