The invention discloses a passive flapping wing applied to a flapping-wing aircraft, which comprises an inner section wing, an outer section wing, a connecting rotating shaft used for connecting the inner section wing and the outer section wing together, and a main control chip used for controlling the movement of the connecting rotating shaft, the connecting rotating shaft is provided with memory alloy, and the memory alloy is connected with the outer section wing through the main control chip. The memory alloy installed on the connecting rotating shaft is connected with the main control chip through a regulation and control circuit, the regulation and control circuit sends square wave signals through the main control chip, then the voltage on the two sides of the nickel-titanium memory alloy sheet is adjusted, the current density of the nickel-titanium memory alloy sheet is adjusted, and the elastic modulus of the nickel-titanium memory alloy sheet is adjusted. And finally, the flapping amplitude and the flapping frequency of the wings are coupled so as to adapt to a complex flight environment.
本发明公开了一种应用于扑翼飞行器的的被动式扑翼机翼,它包括内段翼和外段翼,用于将内段翼和外段翼连接在一起的连接转轴和用于控制连接转轴运动的主控芯片,所述的连接转轴上设有记忆合金,安装在连接转轴上的记忆合金通过调控线路与主控芯片连接,该调控线路通过主控芯片发送方波信号,进而调整镍钛记忆合金片两侧电压,调整镍钛记忆合金片的电流密度,进而调整镍钛记忆合金片的弹性模量,并最终使机翼的扑动幅度与扑动频率相耦合,以适应复杂的飞行环境。
