潜射无人机几种不同折叠翼方案分析比较

Scheme comparison on the folding wing of ubmarine-launched UAV

潜射无人机因其平台的特殊性,有干式、湿式等不同的发射方式,其中关键技术之一是机翼折叠技术。设定潜射无人机的运动过程为从水中到空中,将水流场分为水下无粘条件和水下有粘k-e条件,通过计算不同折叠翼方案潜射无人机的主要气动性能,分析比较得出:机翼纵向后掠部分折叠的方案比较适合潜射无人机的湿式发射,机翼纵向完全折叠进入机身的方案比较适合干式发射。

Because of the particularity of its platform, submarine - launched UAV has different launch modes, such as dry and wet. One of the key technologies is the folding wing technology. For several different folding wing schemes, it designs a sample with the same body structure. A movement process is set from water to air, and the flow field is divided into underwater non viscous conditions and underwater viscous k - e conditions. The paper compares and analyzes the aerodynamic performance calculations of different folding wing schemes. The re- suits indicate that longitudinal swept partially folding wing scheme is more suitable for wet launch, longitudinal completely folding into the fuselage wing scheme is more suitable for dry launch.
