Rocket-carrying telescope-feed boom deployment mechanism

Abstract

The invention discloses a rocket-carrying telescope-feed boom deployment mechanism. The rocket-carrying telescope-feed boom deployment mechanism is characterized by comprising a base and a plurality of nested extension units, wherein the base comprises a lower base, an upper base, a rotating shaft and a locking mechanism; the lower base and the upper base can rotate the boom deployment mechanism by 90 degrees and automatically fix the boom deployment mechanism through the rotating shaft and the locking mechanism; each extension unit comprises a rod-shaped cylinder, a nested pipe clamp fixed at one end of the rod-shaped cylinder, and a stop locking mechanism arranged on the nested pipe clamp; the other end of the nested pipe clamp is nested into the rod-shaped cylinder of the next extension unit so as to limit the movement of the rod-shaped cylinder of the next extension unit; the base is connected with the rod-shaped cylinder at the bottommost end of the extension units through the upper base, and the diameters of the rod-shaped cylinders gradually decrease according to the design sizes and assembly space; and the boom deployment mechanism also comprises a connecting ring.

Description

technical field [0001] The invention relates to a sleeve-type extension rod deployment mechanism for sounding rocket space science detection, in particular to an arrow-mounted sleeve-type extension rod deployment mechanism. Background technique [0002] Sounding rockets mainly use the detection equipment carried on the rocket to detect parameters such as atmospheric trace components, space electric field, ionospheric electrons, ion density, and electron temperature. Among them, the detection equipment for electrons, ions, and electric fields requires its probes to extend The aerodynamic outer surface of the rocket has a certain distance to avoid the influence of the residual magnetism of the rocket body and the surface layer of the airflow, so it is required to extend these probes with an extension rod expansion mechanism. These extension rod parts are often installed in the rocket fairing or on the joint surface where the rocket body and the engine are separated. Because th...

Problems solved by technology

Foreign countries such as the United States, Russia, Sweden and other countries have successfully used extension rods to detect electric fields on sounding rockets, but there is no precedent for sounding rockets to use extension rods for detection in China.
