The invention relates to an air inlet channel adjustable structure with a rhombic section. The air inlet channel adjustable structure is characterized by comprising a front adjusting side plate, a rear adjusting side plate, a sealing side plate, a driving mechanism, a movable air channel sealing plate, a limiting guide frame and a fixed air channel shell; the throat adjusting capacity of the air inlet channel with the diamond-like section is achieved, the throat area of the air inlet channel is adjusted, then the air inlet flow is controlled, good air inlet matching in a wide speed domain range is achieved, the application range of the air inlet channel is widened, and the limitation that an existing air inlet channel adjusting structure is only suitable for an air inlet channel with a rectangular section is overcome.

    本发明涉及一种菱形截面进气道可调结构,其特征在于:包含前调节侧板、后调节侧板、封严侧板、驱动机构、可动气道封板、限位导向框和固定气道壳体;本发明实现了类菱形截面进气道的喉道调节能力,进行进气道喉道面积调节,进而控制进气流量,实现在宽速域范围内良好的进发匹配,拓宽了该类进气道的应用范围,解决了目前的进气道调节结构只适应于矩形截面进气道的局限性。
