“…Compared to the FADS system using multiple pressure sensors and complex pressure tubing, flexible sensing skin for air data sensing has advantages in terms of its light weight and conformability to curved surfaces. [19][20][21][22][23][24] For example, Callegari et al developed a strip pressure sensor array that could be directly attached to the wing surface to determine the flight parameters. [19][20][21] However, the application of flexible sensing skin can be hindered by the low reliability and short lifetime of flexible sensing devices, which cannot compete with traditional microelectromechanical systems (MEMS) sensors.…”

Accurate perception of flight parameters is essential for the safe and stable flight of small unmanned aerial systems (SUASs). However, traditional flush air data sensing (FADS) systems require complex tubing and fuselage openings. Herein this study, a flexible skin system integrated with a pressure and thermal flow sensor array, and a dual‐sensor fusion algorithm for determining the angle of attack (AOA) and airspeed (V ∞ ), are proposed. By establishing an error back‐propagation neural network, the dual‐sensor fusion modality demonstrates higher estimation accuracy than other modalities that utilize only pressure data or only flow velocity data, achieving mean absolute errors of the AOA and V ∞ of less than 0.16° and 0.37 ms−1, respectively. Moreover, the simulation and experimental results show that sensors placed closer to the leading edge of the wing can provide higher estimation accuracy of the flight parameters. The flight parameters determined using the flexible air data sensing system and dual‐sensor fusion algorithm demonstrate potential application in the flight control of SUASs.
