Abstract

In this study, we use the single-winged seeds flying model to study the relevant parameters. Afforestation used as sowing carrier stay in the air spill design to improve sowing distance. This study is further implemented the method currently carried out by Forestry Bureau for afforestation and soil conservation. This study is funded by the relevant principles of fluid dynamics to explore: physical analysis of the five seeds. Reads as follows: (1) structure and trajectory, (2) advance ratio, (3) lift thrust vs. pitch angle, (4) loading vs. terminal velocity, (5) cut-off angle area.. Finally, this study design some carrier models for testing. Spill sowing the spacing and the drift distance experiment analysis results. With experimental data, (shown in Table 2). This research used easy materials that you can make a lot. Fluid mechanical principles could be excellent learning materials for children to explore the use of teaching aids.
