Light aircraft play a significant role in climate and disaster management operations, such as aerial surveillance, mapping, monitoring, and response, among others. This study aims to contribute to enhanced performance and sustainability of light aircraft operations through effective design of light aircraft wings. Using Abaqus commercial software code, computer-aided modelling and simulation of carbon fibre material was carried out to determine suitability for light aircraft wing. The effect of different lengths of the wing (3500, 5000, 6500, and 7000 mm) on the performance of the aircraft was investigated vis-à-vis the resulting stress, strain, plastic strains and displacement induced. The results obtained indicate that the induced stress ranges from 14.5 MPa to 16 MPa and could reach 25.515 MPa, which is significantly lower than the yield strength of the material (3.20 GPa). Furthermore, a wing length of 5000 mm showed less strain induced and thus more stability compared to others. The equivalent plastic strain and resultant displacement for the various lengths of the aircraft wings at the root chord (central axis) were found to be negligible. The outcome of this study can assist light aircraft developers to optimally harness the potential of carbon fibre for aircraft wing development.
