The invention discloses a drag reduction device of an aircraft and the aircraft, the drag reduction device is located in the front edge of a wing of the aircraft, the drag reduction device comprises a telescopic pneumatic plate, a gear mechanism and a driving mechanism, the gear mechanism is connected with the driving mechanism, the rotation torque of the driving mechanism is transmitted to the telescopic pneumatic plate, and the telescopic pneumatic plate is connected with the gear mechanism. Therefore, the telescopic pneumatic plate moves linearly; the gear mechanisms are located on the two sides of the telescopic pneumatic plate. An opening is formed in the front edge of the wing, and the telescopic pneumatic plate extends to the outer side of the front edge of the wing through the opening; under the condition that the telescopic pneumatic plate is arranged in the front edge of the wing, the aircraft flies in a low-subsonic-speed flight state; under the condition that the telescopic pneumatic plate extends to the outer side of the leading edge of the wing, the aircraft flies in a supersonic flight state, and a detached shock wave in supersonic flight is changed into an oblique shock wave, so that the design balance problem of low, sub, cross and supersonic aerodynamic performance is effectively solved while better design balance is realized.

    本申请公开了一种飞行器的减阻装置及飞行器,该减阻装置位于飞行器的机翼前缘的内部,该减阻装置包括:伸缩式气动板、齿轮机构和驱动机构,其中,齿轮机构与驱动机构相连,驱动机构的旋转扭矩传递到伸缩式气动板上,以使伸缩式气动板直线运动;齿轮机构位于伸缩式气动板两侧;在机翼前缘上设置有开口,伸缩式气动板通过开口延伸到机翼前缘外侧;在伸缩式气动板在机翼前缘内部的情况下,飞行器在低亚声速的飞行状态下飞行;在伸缩式气动板延伸到机翼前缘外侧的情况下,飞行器在超声速的飞行状态下飞行,且将超声速飞行下的脱体激波变成斜激波,有效解决了低、亚、跨、超声速气动性能同时较优的设计平衡问题。
