Design and Validation of Deployable and Lockable Mechanism for Gossamer Spacecraft

Abstract

This passage introduces the researches of Deployable and Lockable mechanism for a new Gossamer Spacecraft built by space apply which can be locked and deployed by its own. This mechanism integrates deploying and locking. Its advantages are simple and reliable. It is based on a serious project “Platform Technology of Gossamer Spacecraft” from Lanzhou Institute of Physics. This project manufactured a model machine, finished the ground experiment, passed the project check. This passage introduces work theory particularly, builds the dynamics models, analyzes experiment results factors and presents measurement methods. Results show that the mechanism designed can meet the project requirement; it can build the foundation for the super-large Gossamer Spacecraft of China and improve the degree of the Aerospace technology application.
