This article presents an experimental approach for evaluating the various flight characteristics of a mahogany seed in its autorotative descent. Analytical formulae proposed by Yasuda and Azuma are used to interpret the results. The findings are used in the development of a sophisticated blade element computational model, primarily to analyse planar autorotating systems. This approximate computational approach is then used to predict the flight performance of mahogany seeds and the results are compared with experimental data. The potential use of the computational model in the design of autorotating systems is then brought to light.

Abstract


This article presents an experimental approach for evaluating the various flight characteristics of a mahogany seed in its autorotative descent. Analytical formulae proposed by Yasuda and Azuma are used to interpret the results. The findings are used in the development of a sophisticated blade element computational model, primarily to analyse planar autorotating systems. This approximate computational approach is then used to predict the flight performance of mahogany seeds and the results are compared with experimental data. The potential use of the computational model in the design of autorotating systems is then brought to light.
