【摘要】 为分析箭的流体力学性能,进而完善射箭动作技术理论,对箭进行了水洞和风洞实验。综合实验结果分析得到:箭保持附着流状态在(-6ο—6ο)攻角;安装螺旋塑胶羽片比平直塑胶羽片的流态要好;在实验攻角范围内,升力系数Cy随着攻角的增大而增大;俯仰力矩系数Mz随着攻角的增大而减小。箭具有纵向静稳定性;有无箭羽对箭体模型的升力Y和俯仰力矩Mz影响很大;箭羽滚转一定角度对升力系数Cy也有一定影响;箭羽是产生升力Y的主要部件,更是使箭体有较大静稳定性的部件。更多还原

【Abstract】 The water tunnel and wind tunnel test on arrow aims to make clear the hydrodynam ics performance of arrows and to improve the technical know-how of archery movem ent. Through the experimental of study, we can give out a lot of conclusion: Wit hin the range of angle of attack(-6° —6°), the arrow can keep the state of at tached flow: The state of flow of the arrow with spiral plastic pinna is better than that of arrow with straight one; Within the experimental angle of attack, t he lift coefficient Cy will become larger with the pitching moment Mz getting s maller with the increase of the angle of attack. The arrow has the vertical stat ic stability; No arrow feather will have great impact on lift force Y and pitchi ng moment Mz; the feather rolling will have some impact on lift coefficient Cy, The arrow feather is the main parts to produce lift force Y and to give the arro w body relatively great static stability.更多还原
