The invention relates to a paving and pasting method of an outer pasting film and a fixed-wing aircraft. The method comprises the steps that a three-dimensional model of the surface of the fixed-wing aircraft is constructed; simulating a flow field condition of the fixed-wing aircraft in a flight state based on a three-dimensional model; spreading the to-be-paved area into a plane; discretization processing is carried out on the streamlines on the plane to obtain linear fitting straight lines corresponding to the streamlines, and included angles between tangent lines of the streamlines and the corresponding linear fitting straight lines are smaller than or equal to a preset angle; performing paving surface identification on the plane based on a discretization processing result; selecting an outer pasting film, and cutting the outer pasting film based on the size and shape of each paving surface to obtain outer pasting film pasting blocks in one-to-one correspondence with the paving surfaces; and the outer film pasting block is laid and pasted on the outer surface of the fixed-wing aircraft. The surface friction resistance of the fixed-wing aircraft in the flight process can be effectively reduced, the fuel efficiency is improved, and the purposes of saving energy, reducing emission and improving the flight efficiency are achieved.

    本申请涉及一种外贴膜的铺贴方法及固定翼飞行器,包括:构建固定翼飞行器表面的三维模型;基于三维模型模拟所述固定翼飞行器在飞行状态下的流场情况;将待铺贴区域铺展为平面;将平面上的流线进行离散化处理,以得到流线对应的线性拟合直线,流线的切线与对应的线性拟合直线的夹角均小于或等于预设角度;基于离散化处理结果对平面进行铺贴面识别;选择外贴膜,基于各铺贴面的尺寸和形状对外贴膜进行裁剪,以得到与各铺贴面一一对应的外贴膜贴块;将外贴膜贴块铺贴至固定翼飞行器的外表面。本申请可以有效降低固定翼飞行器在飞行过程中的表面摩擦阻力,提升燃油效率,达到节能减排、提升飞行效率的目的。
