Propulsion Services
Since our beginnings, one of our main areas of technological development has been the area of liquid propulsion, mainly oriented to the development of propellants for launch vehicles and also small propellants for attitude control of launchers and potential use in the satellite industry.
Regarding small thrusters, we have the heritage of having participated in the development of prototypes of the order of 1, 5 N thrust, monopropellant, at laboratory level, having verified the development capacity of this type of thrusters, being able to adapt to the needs of satellite customers and the space industry in general.
The characteristics of the prototype developed in R+D+i mode are shown below.
1.5 N THRUST MONOPROPELLANT PROPELLER —
Monopropellant engines base their operation on the catalytic decomposition of the fuel, which generates heat and gasification of the fuel. The gases produced are then expanded in a nozzle to produce thrust.

launch vehicle engines —
Regarding higher thrust liquid propellants, we have an extensive experience of more than a decade in the development of Hydrazine/Nitric Acid and LOx/Kerosene engines for launcher prototypes, having as main milestones the design, manufacturing, testing and integration in the TI, T4000, VEx 1A, Vex1B and VEx5A launcher prototypes.
As a reference, the VEx5A first stage engine is shown, the largest propellant developed to date.
Today we are leading as prime contractor in the design of the thrusters for the Tronador II launcher series, taking care of the complete propulsion value cycle: from the definition of requirements, through design, simulation, manufacturing, testing, qualification and integration in the final vehicle.
This experience allows us to adapt to any propulsion solution required by the customer, both for launchers, satellites and spacecraft in general.
