The invention belongs to the technical field of aircraft aerodynamic design, and relates to an aircraft nose noise reduction vortex generator device. The device comprises 13 vortex generators, the seventh vortex generator is positioned right behind the central circular light window of the spherical machine head pod; the 13 vortex generators are arranged towards the two sides along the rear edge of the central circular light window of the spherical machine head pod by taking the seventh vortex generator as the center; the two vortex generators which are symmetrically arranged are consistent in appearance, and the first vortex generator, the second vortex generator, the third vortex generator, the fourth vortex generator, the fifth vortex generator, the sixth vortex generator and the seventh vortex generator are sequentially arranged from the two sides to the middle. Wherein the seventh vortex generator is shortest in length, and the vortex generators arranged on the two sides of the seventh vortex generator are increased in sequence; a gap is formed between the front end of each vortex generator and the central circular light window; and each vortex generator is arranged along the heading direction.
本发明属于飞机空气动力设计技术领域,涉及一种飞机机头降噪涡流发生器装置。装置包括:13个涡流发生器;第7个涡流发生器位于球形机头吊舱的中心圆形光窗的正后方;13个涡流发生器以第7个涡流发生器为中心沿球形机头吊舱的中心圆形光窗后沿向两侧布置;对称布置的两个涡流发生器外形一致,从两侧向中间依次为第一涡流发生器、第二涡流发生器、第三涡流发生器、第四涡流发生器、第五涡流发生器、第六涡流发生器和第七涡流发生器;其中,第七涡流发生器长度最短,其两侧布置的涡流发生器依次增长;每个涡流发生器前端与中心圆形光窗之间存在间隔;每个涡流发生器是顺航向布置的。
