摘要:

针对某一特定形状仿蝉微飞行器的翅膀,进行了瞬时功率特性以及平均功率特性的分析.通过仿真,分析了翅膀在3种典型转动模式下的瞬时功率特性、平均功率与攻角幅值的关系,以及最大功率平均功率比值与攻角幅值之间的关系.结果表明,该型翅膀超前模式下的平均转动气动功率对攻角幅值的变化比较敏感;滞后模式下转动气动功率最大峰值平均值的比值对攻角幅值的变化也比较敏感;而平均拍动气动功率和攻角幅值之间的关系可近似地认为与模式无关;拍动气动功率最大峰值平均值的比值和攻角幅值之间的关系也可近似地认为与模式无关.

Abstract:

Aiming at a simplified cicada wing designed for the micro-aero-vehicle(MAV), simulations of both instantaneous power characteristics and the relationships between the average rotational power and the amplitude of attack angles were put forward in three typical rotational models. The relationship between the ratio of maximal-average powers and the amplitude of attack angles was also investigated. The results showed that both the average rotational power in the advanced model and the ratio of maximal to average rotational power in the delayed model were sensitive to the amplitude of attack angles, and the relationship between the average stroke power and the amplitude of attack angles was affected very little by the rotational model,and the relationship between the ratio of maximal-average stroke power and the amplitude of attack angles was also almost not affected by the rotational model.
