Abstract

The Land Rover Defender was developed from the original Land Rover Series that in 1983 for the first outcome. There are already 68 years in producing of Land Rover Defender by the company. The old design for the Land Rover Defender is considered has no aerodynamic features because related to fuel consumptions. The design was simple design and not futuristic design to the customers. The aerodynamics air drag and lift is the main focus for this project report. Thus, the objective of this study is to do basic study on concept design and analysis of Land Rover Defender’s front area (front bumper and front hood). This done by sketching the 1990’s Land Rover Defender and redrawn it on CATIA software before imported to the HyperMesh for further analysis. Three designs were proposed by modify the blunt edge of the front bumper and the angle of the front hood. The designs then imported to the Virtual Wind Tunnel (VWT) software for the Computational Fluid Dynamics (CFD) analysis to determine the effect of the design on the drag (CD) and lift (CL) coefficient for the stability for the car. The value of the drag coefficient, CD, results in this analysis is 0.639 (Original Design), 0.598 (Custom Design 1), 0.566 (Custom Design 2) and 0.612 (Custom Design 3) while for the lift coefficient, CL results is -0.234 (Original Design), -0.126 (Custom Design 1), -0.216 (Custom Design 2) and -0.137 (Custom Design 3). Increasing the angle of front bumper and front hood affected the result of CD which provide more air flow area, thus the air flow will disperse to reduce CD. For the lift coefficient, by increasing the angle of front bumper and front hood affected the result of CL is negative, which means to keep the vehicle nearer to the ground and makes the vehicle more stable.
