Flow separation on aircraft wings has been notoriously linked with loss of lift and extra drag. Furthermore, the recent development of larger, more efficient Ultra High Bypass Ratio (UHBR) engines requires slat cut backs at the juncture of the engine pylon, which significantly promotes separation at high angles of attack. WP1.5 of Clean Sky 2 (CS2) Large Passenger Aircraft (LPA) Programme has been dedicated to addressing this very issue by developing active flow control (AFC) strategies. Among the various AFC techniques proposed in the literature, the pulsed jet actuator (PJA) control has been regarded as a particularly promising one as it suppression separation effectively and with much lower mass flow than the continuous blowing actuation. WINGPULSE is specifically designed to unlock the potential of the PJA technique by combining the expertise of UNOTT in wind tunnel experiments, high-fidelity simulations and control design and the cutting-edge infrastructure and expertise of large-scale flow control testing at ILOT. The overarching aim of WINGPULSE is to develop and demonstrate PJA concepts for flow separation control with efficiency beyond the state-of-the-art (reducing the net mass flow by a factor of 3-5. UNOTT and ILOT will bring together their respective expertise in Computational Fluid Dynamics, aerodynamics, high integrity wind tunnel testing and development of novel flow control actuation systems, including pulsed jet actuator systems, to deliver the two models that facilitate the flow control test programme for UHBR integration in Clean Sky LPA WP1.5.3.

Independent access to space is a key component of the European Space Policy. The competition is increasing in this area both for the full launching systems and the key subsystems. Cost-effectiveness becomes the main driving factor. HYPROGEO ambition is to study a propulsion module based on Hybrid chemical propulsion. Hybrid propulsion is not a new technology but its application to a transfer module or to a re-ignitable upper stage is very innovative. It is an interesting alternative for the GEO transfer, between the chemical propulsion (bi-liquid) and the new trend of Electrical Propulsion (EP). There are very good synergies and complementarities with the other propulsion activities. The proof of concept (specific impulse, thrust) has been demonstrated. The main technical challenge is the long duration firings. The future development of an operational system, already identified in the current roadmaps, requires advanced R&D work on 4 critical technologies: - Combustion chamber. - High endurance nozzle. - Catalytic injector. - Production, storage and use of high concentration hydrogen peroxide. These R&D activities structure 4 main work packages. A system study ensures the global vision in coherence with an economic analysis, the identification of technical challenges and the consolidation of scientific results. A last work package performs the dissemination of results. An innovative aspect is the fact that the R&D activities are directly driven by the ecvolution of market needs and system requirements. Main expected benefits are: - Green and simpler design (compared to bi-liquid). - Shorter transfer time and reduced cost of operations (compared to EP) A TRL 3-4 level is expected at the end of the project. The impact of the project is secured by the composition of the consortium led by Astrium with the main European actors of the hybrid: it contributes to the consolidation of the European industrial supply chain for Hybrid propulsion. Project duration is 36 months.

The Airframe ITD aims at re-thinking and developing the technologies as building blocks and the “solution space” on the level of the entire or holistic aircraft: pushing aerodynamics across new frontiers, combining and integrating new materials and structural techniques – and integrating innovative new controls and propulsion architectures with the airframe; and optimizing this against the challenges of weight, cost, life-cycle impact and durability.
