The INFRASEAL project, for which funding is requested, is a complementary project to the AirSeal project under implementation at INCD Turbomotors COMOTI with direct funding from the European Commission through the Clean Sky 2 program. The INFRASEAL project proposal was evaluated within the European Commission and strongly recommended for financing (Clean Sky 2 Synergy Label) through the European Structural and Investment Funds (ESIF) and the National Management Authority. The main objective of the proposal for a complementary project INFRASEAL is to expand capabilities for advanced, experimental and numerical investigations, in the vision of air flow characterisation through rotary maze seals for high-performance engines. These extended capabilities are designed to provide the foundation for increasing the usability and efficiency of the Ultra-High-propive Efficiency (UHPE) demonstrator validated by Clean Sky for the short-range/medium-range aircraft market. In order for the AirSeal base project, currently underway within the Clean Sky 2 program, to reach its full potential, a series of complementary activities, in synergy with the activities of the basic project, will lead to the extension of the research and other types of seals with rotary mazes that will equip other types of aircraft. To date, the scalability of the technology for making seals with rotary mazes has not yet been proven. The specific objectives of the complementarity project relate directly to this aspect, aiming at the creation and development of research, experimental and numerical infrastructure capable of validating the application of this concept for significantly higher mass flows, higher temperatures and higher pressure ratios. The main result of the project is a new research infrastructure consisting of an experimental testing platform, which includes an air supply station, an air heating station, control and control systems, dedicated measurement equipment, processing and data acquisition systems. The accuracy of experimental investigation and numerical modelling also needs to be improved in order to increase the depth of the knowledge gained in the field.
