Flush Air Data System - An Advanced Air Data System for the Aerospace Industry

Faults Diagnosis of Self-validating Air Data Sensing System Based on Ensemble EMD and Multiclass RVM

“…The experiment process is follows: 1) data synthesis needs to be done by using equation (22) and (23), and the high-frequency sine signal is simulated to period noise disturbing fault wherein [1,2000] t  is the input variable, and 1 x , 2 x are the output variable, and the composite function is expressed by…”

“…Recently National Aeronautics and Space Administration (NASA) has developed the flush air data sensing (FADS) system, which has replaced the traditional Pitot tube with distributed-mounted pressure points, in order to meet the needs of aircraft stealth capabilities, redundancy design, and high Mach number flight [1][2]. However, in realworld flight, the FADS system cannot acquire its own working status which will directly decide whether the current raw measurements value (RWV) can apply to the following flight control system, i.e., the on-line fault self-detection and self-diagnosis, data selfrecovery and status self-estimation functions are absent.…”

Effects of Pressure Ports Layout on Angle of Attack and Sideslip Estimation in the Flush Air Data System

“…Compared to the traditional air data sensor system based on pitots, Flush Air data Sensing System (FADS) system with greater advantages in accuracy, reliability and scope is widely used. Currently, FADS has been applied on many aircrafts with excellent performance, such as F-14, F-15, F/A-18 [2] , X-31 [3] , X-33 [4] , X-34 [5] and X-43a [6] .…”

Fads系统在尖楔前体高超声速飞行器中的应用

“…国外相关研究表明, FADS 系统已成功应用于 F-15, F-14, F/A-18, X-33, X-34, X-38 等前身呈钝体的 飞行器和再入飞行器 [7][8][9] . 国内研究人员 [10,11] 对运用 于钝前体 FADS 系统的求解算法进行过深入研究, 但…”
