Based on the development status and problems faced in the use of helicopter sensors, the application of wireless sensors in helicopter is proposed in this paper. The usage scheme of wireless sensors application in different stages is proposed according to the definition and advantage of wireless sensors. A distributed structure of “wireless + wired” is adopted as the scheme in the primary stage. Furthermore, a fully wireless interconnection structure is adopted as the scheme in the advanced stage. The foundation for further research on the improvement and optimization of helicopter sensors is laid by this research.
