What Does 25kN Mean?
The Brazilian rocket engine startup, Navollo Aerospace, recently announced their SD-25 engine project, specifying its thrust at 25kN. Let’s break down what ’25kN’ actually signifies. The ‘k’ stands for kilo, meaning thousands. So, 25kN represents 25,000 Newtons of force. Newton is the standard unit of force in the metric system; roughly, it’s the force needed to accelerate a 1 kilogram mass at a rate of 1 meter per second squared.
To put that into more relatable terms, 25kN is equivalent to lifting approximately 2,500 kilograms (roughly 5,500 pounds) continuously. This level of thrust is substantial for a rocket engine, especially one being developed by a smaller startup. It provides the power needed to overcome gravity and accelerate a vehicle upwards. The higher the thrust, generally speaking, the more weight – or payload – a rocket can carry.
A 25kN engine like the SD-25 opens up several possibilities. While it might not be sufficient for launching large satellites into geostationary orbit, it’s well-suited for suborbital flights (like those used for research or tourism) and launching smaller satellites into low Earth orbit. It also signifies a significant step forward for Brazilian aerospace technology, potentially reducing reliance on foreign launch providers for certain missions.
