The invention discloses a pneumatic range-extending type logistics unmanned aerial vehicle which comprises a vehicle body, vehicle arms symmetrically arranged on the two sides of the vehicle body, cabin type supporting rods connected with the vehicle arms and undercarriages arranged on the lower portion of the vehicle body, and the vehicle arms have high-lift airfoil profiles with the maximum relative thickness of 20.06% at the chord length of 27.5% and the maximum camber of 7.84% at the chord length of 40.2%. The large-thickness high-lift wing type vehicle arms are adopted, so that the vehicle arms can provide most lift force for the unmanned aerial vehicle in the cruising stage while providing unmanned aerial vehicle structure support and large enough internal containing space, the lift force requirement for a rotor wing power system is greatly reduced, rotor wing power consumption is reduced, the cruising efficiency is remarkably improved, and the endurance time is remarkably prolonged; the cruising flight speed is improved, and the range extension of the unmanned aerial vehicle is achieved in an aerodynamic mode.
本发明公开了一种气动增程式物流无人机,包括机身、对称设置在机身两侧的机臂、与机臂连接的舱式撑杆、设置在机身下部的起落架,机臂拥有在27.5%弦长处,具有20.06%的最大相对厚度,在40.2%弦长处,具有7.84%的最大弯度的高升力翼型剖面。本发明采用大厚度高升力翼式机臂使得机臂在提供无人机结构支撑和足够大的内部容纳空间的同时,还能在巡航阶段为无人机提供大部分的升力,从而大大降低对旋翼动力系统的升力需求,降低旋翼功耗,显著提高巡航效率和续航时间,提高巡航飞行速度,以空气动力学方式实现无人机的增程。
