Increasing the Number of Uses of Filling Tube Connector in Spacecraft via Heat Treatment, Torque Management, and Ceramic Coating
Publication: Journal of Aerospace Engineering
Volume 27, Issue 1
Abstract
The filling tube connector, made of 1Cr18Ni9Ti, is a key part of the propellant injection in spacecraft. When reused, the material is prone to cold welding and abrasion that leads to sealing failure. This paper studies the antiwear and sealing abilities of the filling tube connector when applied with a ceramic coating, heat treated, or subjected to tightening torque management. The results reveal that these methods can greatly extend the life of a filling tube connector.
