The invention relates to a vortex generator, which is arranged on a pneumatic surface of an aircraft and comprises: a support shaft fixedly mounted on the pneumatic surface; the vortex generator further comprises a memory alloy spring, the first end of the memory alloy spring is attached to the supporting shaft, the second end of the memory alloy spring is attached to the blade, and the initial length of the memory alloy spring changes along with temperature changes. And the blades are driven to rotate between the first position and the second position around the supporting shaft. According to the vortex generator, active adjustment of the deflection angle of the vortex generator can be achieved along with changes of the environment temperature, separation of airflow and airfoils is effectively controlled, the separation degree of the airfoils is reduced, meanwhile, redundant resistance is not additionally increased, and the purposes of increasing the lift force of an aircraft, improving the torque characteristic and damping are achieved. In addition, the invention also relates to an aircraft comprising the vortex generator.

    本发明涉及一种涡流发生器,该涡流发生器设置在飞行器的气动表面上并且包括:支承轴,支承轴固定地安装于气动表面;以及叶片,叶片枢转地安装到支承轴,其中,涡流发生器还包括记忆合金弹簧,记忆合金弹簧的第一端附连到支承轴,而记忆合金弹簧的第二端附连到叶片,其中,记忆合金弹簧的初始长度随着温度的变化而变化,以带动叶片围绕支承轴在第一位置和第二位置之间旋转。该涡流发生器能够跟随环境温度变化而实现涡流发生器偏转角度的主动调整,有效控制气流与翼面的分离,并且在降低翼面分离程度的同时,不额外增加多余的阻力,实现了增加飞行器的升力和改善力矩特性以及减震的目标。另外,本发明还涉及包括涡流发生器的飞行器。
