摘要
采用动力学方程对抽象简化后的风筝模型进行分析,从理论上探究风筝在重力场、风速场中受牵引力作用下的起飞最优方式、抬升稳定平衡和高空稳定平衡原理。起飞阶段,应调整牵引线与风筝面的张角,增大相对风速,获得最大抬升力;抬升到静止阶段,应通过合理配重增加稳定力矩,以维持风筝姿态稳定。根据理论分析结果,对比了几种特定风筝的优势和缺陷,为风筝生产制作提供物理学理论建议。
The study analyzes the kite model after the abstraction and simplification through using dynamic equation,and theoretically explores the optimal method of kite flying in gravitation and wind speed field under traction,and the equilibrium principle of the stable equilibrium of lift and high altitude.It is suggested to adjust the field angle of pull wire and kite surface,increase related wind speed,and get the greatest lifting power in flying stage;increase stable stabilizing moment through rational additional weight,and stabilize kite posture in static stage.According to the theoretical analysis results,the study compares the advantages and disadvantages of several specific kites,and provides suggestions for physics theory for kite production.
