HyImpulse, spun out of the German Aerospace Center in 2018, is developing small orbital rockets using paraffin-based hybrid propulsion.
PRE-REVENUEHyImpulse is a German launch startup developing small orbital rockets using innovative hybrid propulsion technology with paraffin-based solid fuel. The company was spun out of the German Aerospace Center (DLR).
HyImpulse Technologies was founded as a spin-off from the German Aerospace Center (DLR) to commercialize hybrid propulsion technology. Their approach uses paraffin-based solid fuel combined with liquid oxygen, offering a simpler and safer alternative to traditional liquid or solid rocket engines. The company is developing the SL1 small launch vehicle targeting the growing small satellite launch market in Europe.
