摘　　要：为了提高水下滑翔机的滑翔效率,本文提出一种翼身融合水下滑翔机。采用融合式的翼梢小翼,减弱翼梢效应;针对高升阻比的设计指标,将升降翼、襟翼特征引入滑翔机设计中,并定量给定各机构的指标参数量值;针对水下滑翔机的设计指标,完成翼身融合水下滑翔机的总体设计;基于模块化设计思想,对水下滑翔机的功能模块分舱独立设计,提高水下滑翔机的故障存活率;针对翼身融合的水下滑翔机的滑翔速度较小,提出大浮力调节装置,大大提高滑翔速度,提升抗流能力;基于有限元理论,对耐压舱室强度与稳定性进行数值计算与分析,结果表明各舱室满足水下工作要求。本文提出的翼身融合水下滑翔机,升阻比性能优越,可以实现对海洋环境的长时序观测任务。In order to improve the gliding efficiency of underwater glider,this paper proposes a wing-body fusion underwater glider.Adopt fusion winglet winglets,sincere and weak wingtip effects;for the design index of high lift-to-drag ratio,the characteristics of elevator wing and flap are introduced into the design of glider,and the index parameter value of each mechanism is quantitatively given;for water The design index of the glider has completed the overall design of the Blended-wing-body underwater glider;based on the modular design idea,the functional module of the underwater glider is independently designed to improve the failure survival rate of the underwater glider;for the Blended-wing-body The glide speed of the underwater glider is low,and a large buoyancy adjustment device is proposed,which greatly improves the glide speed and improves the flow resistance.Based on the finite element theory,the numerical calculation and analysis of the strength and stability of the pressure cabin are shown.Each cabin meets the requirements for underwater work.The wingbody fusion underwater glider proposed in this paper has superior lift-to-drag ratio performance and can be used to observe the long-time observation task of the marine environment.
