| Abstract | Wigetworks Pte Ltd, a local spin-off company aiming to revolutionize the marine transport industry by marketing and being the lead manufacturer for the world's first commercialized WIG vehicle. The objective of this collaboration was to design, fabricate and test fly a small scale WIG effect craft. Based on the literature survey conducted, no research/published papers on a small scale WIG craft were available because many existing WIG crafts were of a large scale, up to the size of commercial jet aircraft. Even so, the amount of published data on existing WIG was also limited as not much serious development had been done since the end of the Cold War when the government of the former Soviet Union stopped its support for WIG projects. Hence the motivation behind this project was to gain a better insight and understanding of the aerodynamics of a small scale WIG and to obtain the aerodynamic characteristics of the craft which could be used for future developments of such a vehicle. One of the main challenges of this project was that it required multi-and interdisciplinary skills. Therefore, this project was done as a team consisting of three other members dealing with their respective areas: Structures, Propulsion and Stability, and Control. The nature of this project also includes analyses, fabrication and field tests which involve the integration of knowledge and skills from different specializations. ii Another challenge of this project was the lack of technical data available for a small scale WIG craft. Analyses and data for a small scale WIG had to be carried out through one hundred over Computational Fluid Dynamics (CFD) runs to get the qualitative relationships between the aerodynamic forces and moments with different dependent variables. Good Computer Aided Design (CAD) modeling skills, proper mesh control and understanding of numerical methods are also needed to model the physics of ground effect aerodynamics and to ensure the predicted results are as accurate as possible. Fifty over hours of flight tests were conducted both indoor and outdoor for validation of the lift and drag predicted by CFD at different condition. On board instruments were mounted onto the craft during the flight tests to quantify the test results for validation. From the flight tests results, this craft was proven to have amphibious capabilities as it was able to operate over both land and water surfaces, and it performed as expected from the CFD results.
