The invention discloses a large-load fixed-wing bomb dropping unmanned aerial vehicle, and relates to the technical field of unmanned aerial vehicles. The large-load fixed-wing bomb-dropping unmanned aerial vehicle is composed of a vehicle body, main wings, ailerons, a horizontal tail wing, a vertical tail wing and a rudder. A main beam of the main wing is formed by CNC (computer numerical control) processing of a PMI (polymethacrylimide) material, and thin-layer carbon sheets are adhered to the upper and lower parts of the main beam and are The aileron PMI foam is made of a material; the horizontal empennage, the vertical empennage and the rudder are of cork wood frame skin structures; the fuselage adopts four square carbon tubes as a longitudinal main force transmission structure to bear main loads in the flying process; the power system mainly adopts a two-stroke 3.5 cc methanol engine as a power source, and is provided with a set of speed reduction group gears, so that the rotating speed is reduced, and the output is increased. Compared with an existing design, the loading capacity of the unmanned aerial vehicle system is improved, meanwhile, light weight, low cost, high loading capacity and high maneuverability are taken into consideration, and after the missile cabin is transformed, specific tasks in other fields can be executed by additionally installing instruments and equipment in other fields.

    本发明公开了一种大载重固定翼投弹无人机,涉及无人机技术领域。本发明所提出的大载重固定翼投弹无人机由机身、主翼、副翼、水平尾翼、垂直尾翼与方向舵构成。主翼的主梁由PMI材料CNC加工而来,上下胶粘薄层碳片并使用凯夫拉纤维捆绑;副翼PMI泡沫为材料;水平尾翼、垂直尾翼与方向舵为轻木框架蒙皮结构;机身采用四根方碳管作为纵向主传力结构,承担飞行过程中的主要载荷;动力系统主要为一台两冲程的3.5cc甲醇发动机作为动力源,并有一套减速组齿轮,减小转速,增大出力。本发明相较于现有设计,提高了无人机系统的载重量,同时兼顾轻量化、低成本、高载重、高机动性,同时其弹舱改造后加装其他领域的仪器设备便可执行其他领域的特定任务。
