There's no "combustion chamber" on the demonstrator;- it's a cold rocket using decomposed HTP;- they claim this can get into space? They're also assuming 1g acceleration as well as there's no inertia factor on the tank pressure.

I've not figured out the tank construction yet but it's not following the route I would expect for a filament wound structure but "it's the lightest such pressurised tank ever made"?

Yet to see any sign of carbon or vacuum bag consolidation or auto-clave. It's either staggeringly clever or ........   

First commercial payload launch in just under 2 years

At least it's entertaining so I'll await next instalment with interest.

Michel,

Thank you for posting the video.  It will be fascinating to see how the testing of their demonstrator turns out.  The materials being used seem very basic for the application to space flight.

... but most suitable for industrial display/mock-up/client/investor/audience display pieces. Little else.

I don't see anyone (or robot) cutting metal here.

Thanks, i look closely on progress of ARCA, there project is quite interesting

Why, do they need it ?
That's Demonstrator for Aerospike rocket engine nozzle
you don't need fancy robots to make that.
after Demonstrator 3 is successful, it's time for robot action on Haas 2CA construction...

It seems to be an aerodynamic test article, essentially a wind tunnel model not for a wind tunnel. For that purpose, simple and low-cost construction makes sense. If this a sham, and hey it could be,  this is not the indicator.

Did I miss something? Apparently this is a catalyst break-down only 'cold' steam rocket. It still gets hotter aft of the catalyst than any resin suspended glass/carbon/Kevlar structure I know of can handle. How are they cooling the hot side of this steam engine?

(heat-sink?).
