We believe the best way of winning the space race is by building our own tracks. That is why we created HyPrSpace, redefining propulsion with a one-of-a-kind rocket.

Thanks to a robust and reliable patented hybrid rocket technology, HyPrSpace is giving Europe a cost-effective and sovereign path to space. We call it ‘Baguettes’.

With over 90 experts on board and still growing, HyPrSpace is on a mission of changing the space industry.

A patented design
for the combustion

HyPrSpace has overcome a 50 years technological barrier by creating a thin, annular combustion chamber that maintains an optimal efficiency from lift-off to orbit, regardless of the size of the rocket.

Our technology mixes benefits without drawbacks

Hybrid is a combination of liquid and solid propulsion technologies. A liquid engine allow thrust modulation and high performances, but is very complex, thus expensive. Solid is very simple and cheap, but suffers from low performances and poor control possibilities. HyPrSpace hybrid has great performances, thrust modulation while remaining simple and cost-effective.

Pressurizing
the engine with helium

To maintain a high pressure flow in the combustion chamber, we integrated an helium tank that “pushes” our oxidizer into the engine.

The only rocket engine without turbopump

Unlike 99% of rocket engines, HyPrSpace’s patented architecture runs without turbopump -one of the most expensive and complex parts in traditional propulsion systems. Thanks to our pressure-fed engine, we’re able to reduce by 40% the cost of our launcher.

A patented design

HyPrSpace has overcome a fifty-year barrier by creating an ultra-thin annular combustion chamber that ensures stable mixing and high efficiency. This drastically simplified

Simplicity
and Robustness

Thanks to its patented architecture, HyPrSpace’s hybrid engine eliminates turbopumps and excess components (+/- 30 times fewer parts than traditional rocket engines). This design reduces failure risks, facilitate the supply chain and assembly, and delivers proven reliability in hot-fire tests.

HPRS-SPLRBST
> 927492

Safe Operation

Solid HDPE fuel and liquid oxidizer cannot react without an initial ignition, which highly reduces explosion risks. It is easy to store, and our previous test campaigns on DGA (General Directorate of Armament) infrastructures have shown that it is safe and fast to operate.

HPRS-SPLRBST
> 927492

Cost-Effective

Fewer parts means lower production costs and shorter lead times. Our technology, turbopump less, with a very simple supply chain, promises highly competitive prices at every scale.

HPRS-SPLRBST
> 927492

Sustainable

Our architecture allows us to use a wide range of propellants. We decided to use recycled HDPE for it’s low carbon footprint and high availability for production and supply. But the search for sustainability is not over, at every step we try to find the right solutions.

OUR PARTNERS AND

Major Contracts

Baguette One

> CONTRACT NAME : PADA1
‍> FRANCE 2030 ET BPI

PADA1 is our answer to the call for project for the development of a microlauncher by France 2030 program and BPI France. HyPrSpace leads a consortium with CT Engineering and Telespazio France to finalize the design of OB1 (Orbital Baguette One) and conduct the inaugural flight of suborbital rocket Baguette One. This demonstrator aims to validate ‘in-flight’ our patented hybrid propulsion technology.

OB1

> CONTRACT NAME : R2D2
> CNES WITH FRANCE 2030 ET BPI

HyPrSpace’s first commercial contract with the CNES, R2D2, calls for five launches carrying payloads up to 235 kg to Low Earth Orbit. Designed to guarantee France’s strategic access to space autonomy by acquiring a capacity for the reactive launch of smallsats, this contract comes in complement of the PADA1 project and recognizes HyPrSpace as a key player of space industry.

Roadmap

Even before HyPrSpace was officially founded, Lily was the very first hybrid engine of our startup. This early test, dating back to the end of 2018, was the spark that ignited a flame now carried by a team of 90 people.Fun fact: the firing was filmed by our favorite YouTubers, Hugo and Maxime Lisoir!

The arrival of the first version of our beloved small demonstrator: Joker. At 1/20th scale compared to our full engine, Joker has allowed us to test and implement improvements to our innovative architecture over the years.

This was also the start of our partnership with DGA EM (Gironde test site), where Joker 1 famously became our first engine to implode (oops).
