Strength Testing of Fabric Composite Material and Impact Simulation for Airbag Landing System

Abstract

The “Orion crew exploration vehicle” of NASA takes airbag as one way of landing system, which can reduce the landing weight, maintain the reposefully landing of the vehicle, protect the detector during recycling. In this paper, taking into account the material quality and the change during soft-landing of the airbag, the tensile mechanical properties tests of plain weave composite material airbag have been conducted at different temperature and different silicone coating thickness. Based on the material parameters of the test, the finite element model has been created to obtain the inner pressure and the overload curve of the airbag which has a certain angle with the ground. The result shows that the airbag made of fabric composite material can realize the landing and recycling of the vehicle.
