• • The flexible sensing patch integrates a capacitive differential pressure sensor array and a vector flow sensor, enabling simultaneous measurement of AOA, AOS, and airspeed in a single device, overcoming the integration limitations of rigid sensors.
• • The dual-layer capacitive differential pressure sensor achieves a resolution of 12 mPa within the low-pressure range of 0–1 Pa, demonstrating superior sensitivity and linearity compared to traditional single-layer sensors, critical for detecting subtle pressure changes at leading edges.
• • The PVF algorithm introduces spanwise velocity (Vz) based on the classic three-sensor algorithm, decoupling AOA and AOS and reducing computational complexity, which is essential for real-time flight control in miniaturized UAVs.
• • CFD simulations validated the PVF algorithm's reliability under wind tunnel conditions, confirming its potential for high-precision flight parameter detection in complex aerodynamic environments.
