A Multi-stage Driven Rod Type Nose-cone Variant Mechanism

Abstract

The invention discloses a multi-stage drive link type nose cone variant mechanism, which includes a first-stage link mechanism, a second-stage link mechanism, a third-stage link mechanism, a bending deformation mechanism and a locking device; the first-stage link mechanism The rod mechanism, the second-level linkage mechanism, the third-level linkage mechanism, and the bending deformation mechanism are connected in sequence; the locking device is installed on each level of linkage structure; the first-level linkage mechanism, the second-level linkage mechanism, the third The connecting rod mechanism of each stage is used to drive the connecting rod mechanism of each stage and its nose cone shell to move axially through the hydraulic drive of stages to complete the axial extension and deformation of the nose cone; the locking device is used when the connecting rod mechanism of each stage is deformed in place, The position is locked; the bending deformation mechanism is used to drive the overall movement of the connecting rod mechanisms at all levels to complete the bending deformation of the nose cone. The invention can realize axial multi-stage stretching deformation and unilateral bending deformation, and at the same time can realize movement limitation and deformation locking during the deformation process of the nose cone.

Description

technical field [0001] The invention belongs to the technical field of aerospace vehicles, and in particular relates to a multi-stage drive link type nose cone variant mechanism. Background technique [0002] Aerospace vehicles, as a new type of aerospace vehicle that includes aviation and aerospace technology, need to experience two different flight environments, the atmosphere and space. However, at present, most of the research on variant aircraft is centered on the wings, and there are very few variant studies on the nose cone, and most of them stay in the design of aerodynamic configuration and the analysis of aerodynamic characteristics. The posture and shape of the nose cone part also greatly affect its maneuverability, therefore, a nose cone deformation mechanism is needed. Contents of the invention [0003] The purpose of the present invention is to provide a multi-stage drive link type nose cone deformation mechanism, which can realize axial multi-stage extensio...
