自車輪發明以來，載具持續改進及發展，其主要目標為製造更先進、快速和節能之載具，達到降低營運成本同時實現環保。但相比其他運輸載具而言，水面上的運輸發展仍相對緩慢，當前的異地效應機(Wing-in-Ground Effect Vehicle)為利用翼地效應結合飛機與輪船的機種。在利用軟體X-foil仿真幾種機翼形狀後，發現NACA 4112因其高升力的性質為最適合此機種之機翼。吾人所設計之載具概念為翼展14.93 m之八人座模型，並使用軟體XFLR5進行小板法分析(Panel Method Analysis)，探討如阻力、起飛速度、推力與地面高度等最佳參數。結果顯示，此機種與傳統飛機相比性能有顯著的提升，約提高了60%之升阻比。因此本研究設計並分析等比例縮小1/5倍之八人座模型版本，結果顯示其與原尺寸相當接近，另外吾人也進行了參數優化研究，於CATIA V5中對於等比縮小1/5之版本有詳細的細節設計與概念，以供未來進行實驗研究可以獲取進一步之優化數據。

Right from the invention of the retro wheel, vehicles have been under consistent improvements with the main goal of shaping more sophisticated, swift, and more energy-efficient vehicles with the reduced cost of operation and being ecofriendly. But the transport on the water surface is still relatively slow in comparison with other sorts of travel. The present “wing-in-ground effect vehicle” is a vehicle that operates utilizing the “wing-in-ground effect” phenomenon. After testing several airfoil profiles for this vehicle in X-foil it is found out that NACA 4412 is the most suitable profile for this application due to its high lift characteristics. Our proposed vehicle is conceptually designed as an eight-seater model with 14.93 m wingspan and a panel method analysis is done using XFLR5 software to study, to understand, and to calculate the parameters such as drag polar, take-off speed and force required to drive the vehicle and optimal ground height. And these results show a compelling improvement in performance characteristics with an approximately 60% increase in lift to drag ratio than a conventional airplane. Hence a scaled-down version of the eight-seat model with a 0.2x scale is designed and analyzed which showed similar results to that of a full-scale model. Subsequently, a parametric optimization study is done. A detailed design is carried out in CATIA V5 based on the conceptual design of the 0.2x scaled-down model for future purposes to carry out an experimental investigation to attain further optimization data.
