Abstract
  • Recent interest in nano aerial vehicles (NAVs) has sparked an increase in research on the mechanics of biological flapping flight. The ability of NAVs to fly in confined spaces and perform tight maneuvers make them a valuable technological asset. Researching the mechanisms behind small-scale flapping flight promises progress toward the development of such vehicles. This thesis expands previous work on a numerical model of Tree Nymph (Idea leuconoe) hovering flight. The model of the butterfly and the genetic algorithm used for optimizing flight parameters were first reviewed, then improved to streamline the data collection process. Parallel processing was introduced to reduce computation time, automatic result generation was implemented to remove the need for manual transcription, optimization precision was increased significantly, and the ability to continue optimization of older parameter sets was developed. The model was then expanded to cover steady forward flight. Forward flight was then studied in relation to the butterfly body’s pitch angle. Pitching the body forward was resulted in a forward velocity requiring adjustments of other flight parameters such as wing and abdomen parameters. In addition, the effects of flapping frequency and body mass on the steady forward flight were observed. A direct relationship between flapping frequency and upward velocity was found, although large deviations produced very unstable results. Conversely, an indirect relationship was found between mass and ascent rate.
