propulsantes

Propulsantes are a class of chemicals used for making rocket fuel and other high-energy propellants. The term is sometimes translated from French as "propellants" or "propulsive agents". They are typically composed of one or more components that are combined to produce a desired set of properties, such as thrust, specific impulse, and stability.

Propulsantes are used in a variety of aerospace applications, including launch vehicles, missiles, and spacecraft propulsion systems. They are often designed to be easy to handle and store, while still providing a high degree of performance in terms of thrust and specific impulse.

The most common type of propulsante is the liquid fuel, which is a mixture of a liquid hydrocarbon fuel and an oxidizer. The two most common types are the RP-1/LOX and the UH-25/LOX combinations. RP-1 is a refined petroleum-based fuel, while LOX is liquid oxygen. UH-25 is a different type of fuel, made from a combination of kerosene and some other substances. Another type of propulsante is the solid rocket propellent, which is composed of a mixture of fuel and oxidizer that is cast into a solid form.

In the past, propulsantes were often produced by the military-industrial complex in various countries. However, today the production of propulsantes has increased with the development of commercial launch vehicles and the increasing use of private rocket companies and development of commercial rocket propulsion systems. Despite its widespread use, the term "propulsante" is not widely known in English.

Commercial proprietary names such as RP-1, UH-25, and others are more commonly used in English speaking countries.
