HyPrSpace

HyPrSpace is a European company developing a hybrid rocket engine. Its goal is simpler, safer and lower cost access to orbit. The company says it is backed by CNES, European institutions and private investors, and that it wants to give Europe an independent route to space.

The site says the engine is the first scalable hybrid rocket engine. A hybrid mixes liquid and solid propulsion. The company explains that liquid engines allow thrust control but are complex and costly, while solid engines are simple and cheap but harder to control. It says its hybrid keeps thrust control while staying simple.

The design is patented. It uses an annular layout with HDPE fuel grains. A helium tank pushes the oxidizer into the engine, so the engine runs without a turbopump. The company says this removes one of the most costly and complex parts of a normal rocket engine.

On launch options, customers can choose a dedicated flight, a lead flight or a shared flight. Payloads named are picosats, CubeSats and smallsats up to 250 kg. The site has a form to pick launch options, orbit and timeframe.

The company says more than 90 experts work there and the team is still growing. It calls its rocket engines Baguettes. The site has a contact form for business, career and press, and a page for open positions.
