| 摘 要： | 采用数值法计算了膜扑翼飞行器的气动力,并与实验结果进行了对比.将惯性力和刚性扑翼产生的气动力作为原始载荷,采用有限元法计算了膜扑翼的变形,分析了此变形引起的气动力的变化.与实验结果的对照表明,该计算结果有较好的可靠性.与刚性扑翼相比,膜扑翼对升力的影响不大,但是大大地增大了推力的正峰值,使得推力有较大的增加,从而改善了扑翼飞行器的气动性能.

| Abstract: | The numerical method to study aerodynamics of the flapping-wing micro aero vehicles (FMAVs) was adopted, and the result was compared with the experimental data. The finite element method was employed to calculate the deformation caused by the inertial force and aerodynamic force of the rigid flapping-wing, and the change in aerodynamic force caused by the deformation was analyzed. Comparison with the experimental data showed the reliability of the calculation results. Compared with the rigid flapping-wing, the membrane flapping-wing affects the lift little, but increases the thrust because the positive peak value of thrust increases greatly, thus improving the aerodynamic performance of flapping-wing aerial vehicles. |
