Our Vehicle

Orbex aerospace engineers have completely re-thought and re-designed the orbital launch vehicle, from avionics and software to structures and propulsion.

We use a wide range of advanced materials and techniques to create each launch vehicle, including the use of additive manufacturing for almost the entire propulsion subsystem and carbon fibre / graphene composites for the main structures and tanks.

Low carbon fuel
The use of a renewable, bio-propane fuel that cuts carbon emissions by 90% compared to old-fashioned hydrocarbons
Modern architecture
A novel architecture that saves around 30% of inert mass increasing efficiency by 20%
3D Printed Engine
Lightweight, high performance 3D printed rocket engines, uniquely manufactured in a single piece, without joins
Smart ignition
A redundant ignition system with no moving parts or electrics for on-orbit re-start and circularisation
Innovative turbo-pumps
Independent low-temperature turbo-pumps driving each stage 1 engine
Flight proven GNC
Flight-proven guidance, navigation and control (GNC) algorithms

Polar Orbit

Space tolerant avionics
Modern, lightweight, space-tolerant avionics platforms
Zero shock separation
Proprietary zero-shock stage separation and soft push mechanisms
Class-leading volume
A 1300mm diameter payload fairing that maximises deployment flexibility
Low mass reusability
Built-in reusability, with an innovative low mass recovery and re-flight system, leaving no orbital debris

World's largest 3D Printed Rocket Engine

Unveiled publicly in early 2019, our 3D printed rocket engine is uniquely manufactured in a single piece without joins in partnership with additive manufacturer SLM Solutions. Given the extreme temperature and pressure fluctuations involved in space flight, this gives the engine an advantage over other rocket engines, which can suffer from weaknesses associated with joining and welding.

It is also the first commercial rocket engine designed to work with bio-propane, a clean-burning, renewable fuel source that cuts carbon emissions by 90% compared to fossil hydrocarbon fuels, supplied by Orbex’s new exclusive BioLPG fuel partner Calor.

Environmentally Focused

Orbex is committed to supporting the ESA’s Clean Space initiative, and is developing one of the most environmentally friendly space launch vehicles ever built.

Our careful approach to environmental impact reduction dramatically improves the carbon footprint and lifecycle impact of the Orbex launch vehicle.
