Objective
Both, the energy and aviation sector rely on gas turbines, a combustion system continuously optimized since its invention during World War II. They constitute a main pillar for tomorrows energy and aviation mix to tackle climate change. However, fuel flexibility is stretched to its limits for conventional combustor designs: combustion instabilities hinder a new generation of safe and low-emission gas turbines. This calls for disruptive design approaches to enforce crucially needed step-change technologies. The overarching aim of TACOS is to break the bottleneck of combustion instabilities by novel, physics-driven design principles based on latest theoretical findings: the combustion community -including myself- has discovered ""exceptional points"" (EPs), which are known from theoretical physics to feature intriguing, counter-intuitive physical properties. Our preliminary results confirm that EPs (i) rapidly switch the combustor stability from unstable to stable and (ii) are well-controllable by both the acoustics of the chamber and the flame characteristics. TACOS takes a leap forward and exploits the unique properties of EPs for the conception of novel combustors by 3 objectives: (A) tailor the characteristics of both gaseous (land-based gas turbines) and spray flames (aeroengines) by carbon-free fuels (hydrogen+ammonia) and sustainable aviation fuels
