Compare with uniaxial single-rotor electric unmanned helicopter (USREUH), the structure of
round multi-axis multi-rotor electric unmanned helicopter (RMMEUH) is very different to
USREUH, and thus its wind field parameters on rice canopy which formed by rotor airflow
are also different. To explore the optimization parameters when the RMMEUH conducted
supplementary pollination, in this study orthogonal tests of three factors (including flight
operating load, altitude and speed) and three levels were carried out to measure the wind …

The wind field parameters on rice canopy which formed by rotor airflow are significantly
difference among different structure of unmanned helicopter. There are direct influence
among the seed setting rate, operating efficiency, and the parameters of wind field on rice
canopy. To explore the optimization parameters when the uniaxial single-rotor electric
unmanned helicopter (USREUH) conducted supplementary pollination, orthogonal tests of
three factors (including flight operating load, altitude and speed) and three levels was …
