The invention relates to the technical field of aircraft nacelle spoilers, and provides a self-adaptive nacelle spoiler device with a folding mechanism and a control method. The device comprises a first-layer nacelle spoiler, a middle-layer nacelle spoiler, a spoiler storage shell and a folding driving mechanism; one end of the first-layer nacelle spoiler and one end of the middle-layer nacelle spoiler rotate around a fixed rotating shaft to be opened or closed; the first-layer nacelle spoiler, the middle-layer nacelle spoiler and the spoiler storage shell are sequentially arranged from top to bottom when the first-layer nacelle spoiler is unfolded, and the first-layer nacelle spoiler and the middle-layer nacelle spoiler are folded and stored in the spoiler storage shell when the first-layer nacelle spoiler and the middle-layer nacelle spoiler are folded and folded; and the folding driving mechanism drives the first-layer nacelle spoiler and the middle-layer nacelle spoilers to rotate to open or close. The nacelle spoiler overcomes the defect that a traditional nacelle spoiler cannot meet different aerodynamic performance requirements of low speed and high speed at the same time, the self-adaptive design idea is adopted, and a multi-section folding telescopic mechanism is used, so that the nacelle spoiler can meet different aerodynamic performance requirements of low speed and high speed of an airplane.

    本发明涉及飞机短舱扰流片技术领域,提供了一种具有折叠机构的自适应短舱扰流片装置及控制方法,所述装置包括头层短舱扰流片、中层短舱扰流片、扰流片收纳外壳及折叠驱动机构;头层短舱扰流片、中层短舱扰流片的一端绕固定转轴旋转打开或收合;打开时自上而下依次为头层短舱扰流片、中层短舱扰流片、扰流片收纳外壳,收合时头层短舱扰流片、中层短舱扰流片折叠收合在扰流片收纳外壳内;折叠驱动机构驱动头层短舱扰流片、中层短舱扰流片旋转打开或收合。本发明克服了传统短舱扰流片难以同时兼顾低高速不同气动性能需求的缺陷,采用了自适应设计思想,使用多段折叠的伸缩机构,使短舱扰流片可以适应飞机低速和高速的不同气动性能需求。
