The invention relates to the field of ornithopters, and discloses a two-section wing type ornithopter with an adjustable attack angle in a flight process. Comprising a fuselage, a skeleton system connected with the fuselage, a left wing and a right wing which are arranged on the two sides of the skeleton system respectively and used for flapping, two sets of up-down flapping driving systems for providing flapping power for the wings on the corresponding sides respectively, and a front-back swing driving system for adjusting the attack angles of the wings; the front-back swing driving system comprises a hydraulic cylinder support and a hydraulic cylinder piston rod, the hydraulic cylinder support is fixedly connected with the aircraft body, the hydraulic cylinder piston rod is hinged to the framework system, the left wing and the right wing which are connected with the framework system are driven to swing along with stretching and retracting of the hydraulic cylinder piston rod, and the attack angle of the ornithopter is changed in the flight process. The attack angle of the aircraft wings can be adjusted, and inner and outer wings can be bent and folded in the spanwise direction. The aerodynamic performance of the ornithopter is improved, and meanwhile the flexibility and the cruising ability of the ornithopter can be improved.

    本发明涉及扑翼飞行器领域,公开了一种飞行过程中迎角可调的两段翼式扑翼飞行器。包括机身,与机身连接的骨架系统、分别设置在骨架系统的两侧且起扑动作用的左机翼和右机翼、两套分别提供对应侧的机翼扑动动力的上下扑动驱动系统和起调节机翼迎角作用的前后摆动驱动系统;前后摆动驱动系统包括液压缸支座和液压缸活塞杆,液压缸支座与机身固定连接,液压缸活塞杆与骨架系统铰接,随着液压缸活塞杆的伸缩带动与骨架系统连接的左机翼和右机翼摆动,改变扑翼飞行器的迎角大小飞行过程中,飞行器机翼迎角可以调节且内外翼可进行展向弯曲折叠。该发明在改善扑翼飞行器气动性能的同时,还可以提高飞行器的灵活性和续航能力。
