Future high performance combat aircraft are increasingly driven by the combined requirements of low observability, high speed operation and high manoeuvrability, together with wide envelope controllability. These requirements introduce a critical design conflict: conventional control surfaces, such as horizontal and vertical tails, elevators, ailerons and rudders, provide effective aerodynamic control, but may introduce penalties in terms of radar signature, integration complexity, aerodynamic efficiency and control effectiveness under complex aerodynamic conditions, especially at high angles of attack. This issue becomes even more relevant for tailless configurations, where the reduction of conventional stabilizing surfaces requires alternative solutions. This thesis investigates innovative aerodynamic control effectors for advanced fighter aircraft, with specific focus on the All-Moving Tip (AMT) concept.
