Abstract

The invention relates to the technical field of aerospace, in particular to a grid rudder structure and a rocket with the same. The grid rudder structure comprises a grid rudder body; a mounting base, wherein a rotating shaft is fixedly connected with the grid rudder body and is rotatably connected with the mounting base; a torsion device, wherein one end of the torsion device is fixedly connected to the rotating shaft, the other end of the torsion device is fixedly connected to the mounting base, and when the grid rudder body needs to be unfolded, torsion force of the torsion device drives the grid rudder body to rotate relative to the mounting base along the rotating shaft; and a locking structure, wherein the locking structure is arranged on the mounting base and is suitable for being locked with the rotating shaft when the torsion device drives the grid rudder body to rotate in place. Through the arrangement of the torsion device, rotation driving of the grid rudder body can be achieved through the torsion force of the torsion device, through cooperation of the rotating shaft and the locking structure, when the grid rudder body rotates in place, locking of the locking structure on the rotating shaft is achieved, and due to the fact that mechanical driving unfolding and locking are adopted, the unfolding and locking reliability of the grid rudder body is improved.

Description

[0001] This application is a divisional application of an invention patent application with publication number CN111238313A. The filing date of the original application is: 2020.03.13; technical field [0002] The invention relates to the field of aerospace technology, in particular to a grid rudder structure and a rocket with the same. Background technique [0003] The grid rudder is a space multi-lift surface system that is arranged in the form of a frame or a honeycomb by an outer frame and a large number of thin grid walls inside. The folding and unfolding of the grid rudder is widely used in missiles and launch vehicles. For example, the folding of the grid rudder can reduce the space occupied by the missile body during storage, increase the number of bombs in a limited space, and unfold during the rocket recovery process. The grid rudder controls the recovery attitude through the grid rudder to ensure that the rocket wreckage can be accurately landed in the set area. ...
