The UPM, an orbital rocket first stage at 100,000 Euro

Updated: Jul 4

In 2022 we’ve predicted that the EcoRocket Universal Propulsion Module (UPM) will be the last major rocket hardware designed and built by ARCA and this will satisfy our needs well into the future.

The ecological, steam propulsion UPM has a thrust of 30 tf and its design and features allows us to quickly implement any application at unprecedented cost effectiveness.

In the case of military applications, the UPM is used to provide the propulsion for the A1 strategic anti ballistic and hypersonic missile interceptor and the 1,200mm caliber target rockets.

In the case of the EcoRocket for the Ami Exploration program it is used in a clustered configuration to provide the propulsion for the first and second stage of the world’s heaviest rocket EcoRocket Heavy.

The UPM allow us to quickly implement any application for the first and second stage for any orbital or suborbital vehicle, for both civilian and military applications, ranging from 30tf for the A1 interceptor, to 12,600tf for the EcoRocket Heavy.

It can also be used as a booster for any existing orbital rocket, enhancing the orbital vehicle's capability in the range of 20%.

Due to its efficient fabrication techniques and the use of ecological steam propulsion technology, the cost of a UPM unit is 100,000 Euro, which allows us to create a series of unprecedentedly cost effective rockets for both civilian and military applications.

If the A1 uses hydrogen peroxide and EcoRocket uses steam/hot water, how is this the same rocket design? Is the catalyst bed somehow modular?

If it really is a duel fuel design, is the performance compromise on the hydrogen peroxide version?

The catalyst bed for the hydrogen peroxide and water mix, and the heating system for the water only are the only major differences between the two configurations. The engine is the same, the tank is the same. In terms of performance they are pretty close with a slight advantage for the hydrogen peroxide 50% + water 50%, in terms of Isp and propellant density.
