The invention discloses a rigid wing and flexible wing combined solar aircraft, which comprises a plurality of fuselages (1), rigid wings (2), an empennage (7), an undercarriage (8) and a flight control system (6), and further comprises a pair of flexible wings (3), the flexible wing (3) is positioned above and behind the rigid wing (2), the projection plane of the flexible wing (3) does not coincide with the rigid wing (2), and the flexible wing (3) is made of a flexible soft material, is formed by head-on airflow stamping and has certain rigidity; wherein at least two rigid frameworks (35) made of light materials are included, the rigid frameworks (35) are connected with the fuselage (1) through supports (4), and electric propellers (5) are installed on the rigid frameworks (35). And solar panels are laid on the upper surfaces of the rigid wings (2) and the flexible wings (3). Through the combination of the rigid wings (2) and the flexible wings (3), the aspect ratio of the flexible wings (3) is greatly improved, the instability of the flexible wings (3) at high wind speed is overcome, the lift-drag ratio of the whole aircraft is remarkably improved, and the effective load of the solar aircraft is greatly improved; meanwhile, the advantage that the flight control performance of the rigid wings (2) and the empennage (7) is good is exerted, the power generation capacity of the aircraft is greatly improved through the solar cell panels on the two wings, the power utilization requirements of a plurality of airborne devices are met, and the solar aircraft can fly in a manned mode and can also meet the requirement for hovering unmanned flight in the stratosphere.
本发明公开了一种刚性机翼与柔性机翼结合的太阳能飞机,包括多个机身(1)、刚性机翼(2)、尾翼(7)、起落架(8)及飞行控制系统(6),还包括一副柔性机翼(3);柔性机翼(3)位于刚性机翼(2)的上方偏后且其投影面与刚性机翼(2)无重合,柔性机翼(3)由柔性软质材料制成并由迎面气流冲压形成的具有一定刚度的机翼,其中包含至少两段由轻质材料制成的刚性骨架(35)并在刚性骨架(35)处通过支架(4)与机身(1)连在一起并在上面装有电动螺旋桨(5);刚性机翼(2)与柔性机翼(3)的上表面均铺设太阳能电池板。通过刚性机翼(2)与柔性机翼(3)的结合,大幅提高了柔性机翼(3)的展弦比,克服了柔性机翼(3)在高风速下的不稳定性,显著提高了全机的升阻比,大幅提高了太阳能飞机的有效载荷;同时又发挥出刚性机翼(2)及尾翼(7)飞控性能好的优点,两副机翼上的太阳能电池板大幅提高了飞机的发电能力,保证了多个机载设备的用电需求,本发明的太阳能飞机既可载人飞行又可满足平流层内滞空无人飞行。
