A Redundant Unlocking and Sequence Controlled Release Mechanism for Small Satellite Launch

Abstract

The invention relates to a release mechanism for redundant unlocking and timing control of small satellite launches, belonging to the technical field of rocket launches; including hatches, frames, hinges, push plates, thrust springs, four slide rails, limit devices, Connecting rod, pressure plate and electromagnetic lock; the top opening of the frame; the hatch is set at the top opening of the frame; the hinge is set at the connection between the hatch and the frame; the electromagnetic lock is set on the side wall of the frame; 4 sliding The rails are arranged axially at the corners of the four side walls inside the frame; the thrust spring is arranged at the bottom inside the frame; the push plate is arranged horizontally at the top of the thrust spring; the pressure plate is arranged at the bottom inside the frame; the connecting rod is vertical It is set on the top of the pressing plate; the limit device is set on the top of the connecting rod; the limit device drives the pressing plate to act together through the connecting rod; The satellite release device improves the reliability of the unlocking device, thereby improving the launch success rate of the external cubic small satellite.

Description

technical field [0001] The invention belongs to the technical field of rocket launch, and relates to a release mechanism for redundant unlocking and timing control of small satellite launch. Background technique [0002] With the development of micro-nano technology and the promotion of application requirements, micro-nano satellites have been deeply studied and widely used in many fields such as scientific research, national defense and commercial use due to their advantages of small size, low power consumption, short development cycle, and low cost. In order to enable universities and scientific research institutions to have more opportunities to participate in space science practice, external cube small satellite refers to a tiny satellite made with special design standards (by Jodi Prig Saur of California Polytechnic State University, CalPoly). The professor formulated the initial relevant standards. The standard external cube satellite adopts the "1U" structure, that is...

Problems solved by technology

[0004] The traditional small satellite release mechanism is mainly based on pyrotechnic separation, which has the disadvantages of being undetectable and undetectable and the impact environment is harsh, which does not meet the needs of repeated testing in ground tests. reliability
