AbstractIn order to understand the optimization parameters including helicoper flight altitude, direction and speed etc., while the unmanned helicopter conducts supplementary pollination, in this paper, a Wireless Wind Speed Sensor Network measurement system (WWSSN) was used to measure the wind field of Unmanned Gasoline Engine Single-Rotor Helicopter (UGESRH) and Unmanned Electric Engine Single-Rotor Helicopter(UEESRH). The measured wind directions of the WWSSN include parallel to the direction of male parent ridge (X), perpendicular to the direction of male parent ridge (Y), and the vertical direction (H). The test results showed that the wind speed value of two types unmanned helicopter is Vx> Vy> Vh, and the wind in direction X is more useful to the supplementary pollination. The wind speed value and wind field width value of UGESRH are significantly greater than the value of UEESRH. The test results also showed that the wind speed is so small while unmanned helicopter flight at the against wind direction compare with its flight at the downwind direction that the wind speed reaching the rice canopy is small and it is difficult to form the wind field width of the rice seed pollination agronomic requirements to meet, and the wind field width is larger in the downwind direction. Comprehensive consideration of various factors, including the operating efficiency and the flight security, the downwind direction is suggested, the UGESRH operated more widely and effected better than UEESRH, while using UGESRH to conduct supplementary pollination.
