Abstract

Theoretical analysis is used to identify the optimum wing planform of a flapping/revolving wing in hover. This solution is of interest as a benchmark to which hovering wing geometries driven by broader multidisciplinary evolutionary or engineering constraints can be compared. Furthermore, useful insights into the aerodynamic performance of untwisted hovering wings are delivered. It is shown that profile power is minimised by using an untwisted elliptical planform whereas induced power is minimised by a more highly tapered planform similar to that of a hummingbird.

摘要

采用理论分析来确定扑翼/旋转翼在悬停时的最佳机翼平面形状。该解决方案作为一个基准很有意义，通过它可以比较由更广泛的多学科进化或工程约束驱动的悬停机翼几何形状。此外，还能对非扭转悬停机翼的空气动力学性能有深入了解。结果表明，采用非扭转椭圆形平面形状可使剖面功率最小化，而采用类似于蜂鸟的高度渐缩平面形状可使诱导功率最小化。
