Abstract

The invention discloses a multi-stage driven connecting rod type nose cone variant mechanism which comprises a first-stage connecting rod mechanism, a second-stage connecting rod mechanism, a third-stage connecting rod mechanism, a bending deformation mechanism and a locking device. The first-stage connecting rod mechanism, the second-stage connecting rod mechanism, the third-stage connecting rodmechanism and the bending deformation mechanism are connected in sequence. The locking device is mounted on each stage of connecting rod structure; the first-stage connecting rod mechanism, the second-stage connecting rod mechanism and the third-stage connecting rod mechanism are used for driving all stages of connecting rod mechanisms and a nose cone shell of the connecting rod mechanisms to movein an axial direction through graded hydraulic drive, and axial stretching deformation of a nose cone is completed. A locking device is used for locking a position when each stage of connecting rod mechanism deforms in place; and the bending deformation mechanism is used for driving all stages of connecting rod mechanisms to integrally move to finish bending deformation of a nose cone. Axial multistage stretching deformation and single-side bending deformation can be achieved, and meanwhile motion limiting and variant locking in a nose cone deformation process can be achieved.

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...
