| Abstract: | The high- reliability of sensors in embedded flush air data sensing system（FADS） of reusable launch vehicle （RLV） is the guarantee of the high reliability of its flight control systems Combining the characteristics of multi manometric sensors＇ redundancy allocation in FADS, an effective method of sensor fault detection based on parity equation is proposed in the paper. The parity equation is designed based on redundancy relations among the measured values, and the FADS sensors fault detection is accomplished successfully by the parity equations. |
| Keywords: | reusable launch vehicle flush air data sensing system fauh detection parity equation |
