SONG Xiu-yi, LU Yu-ping. Research on algorithm in flush airdata sensing system of flying wing vehicle[J]. 2008, (4): 12-14+17. DOI: 10.13873/j.1000-97872008.04.020.
Structures of pressure points and the pressure model of the flush airdata sensing(FADS) system are introduced
the algorithm of linear equations of the overdetermined system is analyzed
and the pseudo-inverse matrix A+ is developed to work out the least-square solution.The definite function model between the calibration factor ε and M ∞
α
β is developed.An idea of dealing with failure points is showed.Solutions of the dynamic pressure and static pressure are worked out by means of the neural network.The result of validation indicates that the algorithm in FADS system of flying wing vehicle can meet the requirement of designing.
