Roger Moore Lecture: ESA Friction stir welding of titanium propellant tanks
London Materials Society joint Meeting with The Welding Institute
Dr Richard Freeman
Titanium propellant tanks are one of the most costly items in the rocket/spacecraft propulsion system. This is due to a combination of the high cost of titanium forgings, long lead time, and the extensive amount of machining that is required during manufacturing. Furthermore, the evolution of larger motor systems is demanding even larger tanks, which threatens to become prohibitively costly if manufactured by traditional methods.
The aim is to reduce the overall manufacturing cost of propellant tanks
