The Armadillo Aerospace X-Ship is coming together nicely according to their latest report:
All engine plumbing and wiring is complete on the big vehicle. We loaded water into the big tank and tested all the valves, with pretty good results. Our distribution manifold has a leak in the weld which will need to be fixed, and the fill port 2″ threads were loosened during the filling process when the giant hose pressurized itself and whipped around a bit. We can’t just weld the inlet fittings, because the check valve is stainless steel, while the rest of the hardware is aluminum, so we may need to weld flanges onto each side and bolt them together.
They seem confident they are close to completion:
If there was catalyst in the engines, the big vehicle is now capable of flight, but we still need to get the drogue cannon worked out before it can land properly. We also need to make some honeycomb panels to protect the base of the tank from exhaust at launch, but we are running out of things to do on it. The base will need a fair amount of rework when we put the full size engines on it, but the basic layout will probably remain the same.
I look forward to news of their first static test of the big vehicle.
