MONO
PROPELLANT
SYSTEMS

Monopropellant High-test highly stabilized hydrogen peroxide propulsion system providing from 1 to 500 N of thrust.

BI-
PROPELLANT
SYSTEMS

Bi- propellant HTP-Kerosene propulsion system providing from 1 to 500 N of thrust, scalable to few kN.

HYBRID
PROPELLANT
SYSTEMS

Hybrid propulsion system, based on HTP and paraffin wax, providing from 100 N to 10 kN of thrust.

OXIDIZER

Our key technology for the oxidizer is highly-stabilized hydrogen peroxide, that is a green and non-toxic propellant.
We perform in-house concentration of our hydrogen peroxide, thus eliminating the transportation issues of highly concentrated H2O2 and allowing us to operate with a concentration level up to 95%. ​
In addition, we have an extensive expertise operating with nitrous oxide and gaseous oxygen.

FUEL

We use paraffin wax for our hybrid propulsion systems. Paraffin wax is a green fuel. In combination with H2O2 as oxidizer, exhaust gases are water, steam and CO2. Thanks to its liquefying characteristic, it provides high regression rates, thus allowing simple single port fuel grains. Our paraffin has thermomechanical performance able to withstand launch vibrations and in-orbit temperature stresses. We can use also polyethylene and polyethylene/paraffine blends depending on customers’ request and on mission specifications.
For our bi-propellant propulsion systems we use kerosene as green propellant.

capabilities

We carry out research and development activities
through a extensive combined numerical-experimental investigations

We are working with paraffin wax as fuel since 2007, casting fuel grains up to 200 kg, acquiring a wide database on fuel types and properties.
We are capable of in-situ concentration to avoid transportation issues of propulsion-grade hydrogen peroxide.
We have performed more than 500 tests on motors, from laboratory scale to full scale, acquiring also flight experience.
