Abstract: Flush airdata sensing system is an advanced airdata sensing system，in which airdata are inferred from nonintrusive surface pressure measurements using a nonlinear pressure model and a nonlinear solution algorithm．The layout of pressure taps in flush airdata sensing system was researched by analyzing the convergence of data calculation under different layouts with ripples algorithm and demonstrated with calculation precision under different layouts with white noise influence.

Key words: Flush airdata sensing system, Pressure tap, Riples algorithm
