Hybrid Rocket Engine

The next best thing to happen for space industry

Hybrid Rocket Engines (HREs) have the potential of becoming the best of rocket propulsion technologies. It is low-cost to develop, manufacture and operate. It cannot explode and uses harmless propellants with no associated toxicity. Thrust modulation, thrust termination and re-ignition are possible, allowing the landing of HRE powered boosters and multiple orbits upper-stage mission.

Combustion efficiency associated with low solid propellant flow rate in large size HRE have been barriers that prevented this technology to be used on orbital launcher. Hybrid Propulsion for Space is developing a technology to improve combustion efficiency while ensuring a sufficient solid propellant flow rate for powering rockets.

With the robustness of the HRE and its ability for landing and reusability, hybrid propulsion is the next technological leap for providing access to Space to the greater number.


Hybrid Rocket Engines (HREs) is a propulsive technology with many advantages compared to liquid and solid propellants propulsion, and yet little used in space transportation. To discover these advantages, take a look on how we will change that and be amazed of what can be done with HRE.
