Analysis of Effect of Wing Layout on Aircraft Floating Characteristics

Once the engine failure or fuel exhaustion above water, the aircraft should be ditching on the water surface immediately. From the perspective of floating characteristics, the overall layout of the wings will affect the float ability obviously. The paper based on the anti-sinking theory of floating characteristics and the discrete analysis method of water intake fragments, calculating the floatation characteristics for upper monoplane and lower mono-plane in different center of gravity. The analysis and conclusion can provide a reference for the safety assessment after ditching and the emergency escape device design.
