Flexible electric field stretching rod unfolding device of sounding rocket

Abstract

The invention discloses a rocket-borne flexible folding type stretching rod unfolding device. The device comprises an electric field stretching rod part and a clamping and releasing unit for clamping and releasing the electric field stretching rod part; the electric field stretching rod part is a flexible carbon fiber folding stretching rod, and the clamping and releasing unit comprises a left clamping plate, a right clamping plate, a left support, a right support, a fuse protector, a fish wire, a left limiting check block, a right limiting check block, an upper base, a lower base and a middle cylinder connecting support. The upper base is connected with the lower base through a base rotating shaft, and the left support and the right support are fixed to the lower base in parallel; the lower end of the left clamping plate is connected with the upper end of the left support through a clamping plate rotating shaft, and the lower end of the right clamping plate is connected with the upper end of the right support through a clamping plate rotating shaft; and a plurality of arc-shaped bosses tightly attached to the folded electric field stretching rod part are arranged on the inner surfaces, in contact with the electric field stretching rod part and an electric field probe, of the left clamping plate and the right clamping plate, so that the left clamping plate and the right clamping plate are in tight contact with a folded electric field stretching rod when being in the vertical state at the same time.

Description

technical field [0001] The invention relates to the field of sounding rocket electric field extension rods, and specifically designs a flexible electric field extension rod expansion device. Background technique [0002] The payload equipment of the sounding rocket includes a double-arm probe-type electric field meter for detecting electric fields. This kind of detection equipment requires its probe to protrude a certain distance from the aerodynamic outer surface of the rocket to avoid the influence of the residual magnetism of the rocket body and the surface layer of the airflow. Two extension rods for detecting the electric field are installed on the joint surface of the rocket arrow and the rocket body. When launching, the electric field boom is folded in the pod. After reaching the predetermined height, the rocket head and body are separated, and the electric field extension rod is unfolded. The electric field extension rod and the double-arm probe electric field met...

Problems solved by technology

But for a three-axis stabilized sounding rocket, the extension of the extension rod must rely on its own deployment drive mechanism.
