| The underwater glider is an autonomous underwater vehicle with fixed wings which is driven by buoyancy.The glider wings and fuselage’s own fluid dynamics performance has important effect on glider’s motion,and being propitious to energy conservation as well.The horizontal plate wing is economical and efficient.We studied the issue of plate wing designing,and discuss the hydrodynamic performance of the fuselage and tail.Sensitivity Analysis was used to filter the key data of horizontal plate wing to simplify the research work.Five parameters: position,angle,length of the wing,aspect ratio,root shoot ratio are selected to be considered during the design.The key data was sequenced by calculation.The hydrodynamic parameters of the plate wing was calculated firstly,secondly,the other parameters was calculated by hydrodynamic calculation and comparison.This method could improve accuracy and reduce work load.The corresponding mathematical model was established for simulation,as well as experiment,to verify the results.The relationship between hydrodynamic parameters and observed parameters were determined by mathematical formula.The force observed proved the correctness and rationality of the design method.We studied glider’s wing and fuselage with the method proved.The Granville equation is simplified to simplify the designing process.The rear wing’s important role in three-dimensional space was proved by studying the motion parameters of rear wing.We initially studied the position of the rear wing based on this conclusion.A succinct method to design the horizontal plate wing was put forward in this thesis,and it is an important reference scenario.The designing process of fuselage is simplified by optimized the shape of the fuselage,and a simple method in designing is provided for designers.The rear wing plays an important role in three-dimensional movement,the conclusion in this thesis provides a reference for the study of rear wing. |
