The invention relates to a manta ray imitating flexible underwater vehicle with chest tail fin flapping, heavy buoyancy gliding and propeller propelling, and belongs to the field of bionic underwater vehicles. According to the appearance and function of manta ray, under the function of flapping pectoral fins and tail fins, a heavy buoyancy adjusting and propeller propelling device is additionally added for the manta ray. The aircraft realizes high maneuvering motions such as forward swimming and steering by utilizing flapping of the left pectoral fin and the right pectoral fin; high-efficiency gliding motion is achieved through heavy buoyancy adjustment, and pitching attitude adjustment is achieved through interaction of the tail fin and water flow during flapping and gliding motion. The manta ray imitating aircraft has the characteristics of high flapping maneuverability and high gliding efficiency, and on the basis, propellers are adopted for auxiliary propulsion, so that the swimming speed and steering and pitching maneuverability of flapping and gliding of the aircraft are further improved, and particularly, the defect that the yawing and pitching maneuverability is insufficient due to the fact that the gliding speed of the aircraft is low is overcome; in-situ steering and rapid pitching maneuvering motion of the aircraft can be achieved.
本发明涉及一种胸尾鳍扑动、重浮力滑翔、螺旋桨推进的仿蝠鲼柔体水下航行器,属于仿生水下航行器领域。参照蝠鲼的外形与功能,在具有胸鳍与尾鳍扑动的功能下,为其额外添加了重浮力调节与螺旋桨推进装置。航行器利用左右胸鳍的扑动实现前游、转向等高机动运动;利用重浮力调节实现高效率滑翔运动,在扑动与滑翔运动时,利用尾鳍与水流的相互作用实现俯仰姿态的调节。仿蝠鲼航行器兼具扑动高机动与滑翔高效率的特点,在此基础上,采用螺旋桨辅助推进,进一步提升航行器扑动与滑翔的游动速度与转向、俯仰机动性,特别是弥补了航行器滑翔速度较慢导致的偏航与俯仰机动性不足之处,可实现航行器原地转向与快速俯仰机动运动。
