Driving Innovation with a Strong Consortium
ISPTech leads a standout consortium that includes renowned European space industry players DLR Institute of Space Propulsion , OHB , and UARX Space .Their combined expertise will be instrumental in elevating the Technology Readiness Level (TRL) of HIP_11 thrusters to prepare for upcoming space missions. The strong interest shown by OHB and UARX underscores the industry’s confidence in HIP_11, opening the door to new applications and collaborative opportunities.
HIP_11 :Born from PhD Research of Felix
A key differentiator of ISPTech’s propulsion portfolio is HIP_11 , a game-changing hypergolic system created during Felix’ doctoral work at the German Aerospace Center (DLR). Originally developed to offer a low-toxic alternative to conventional hyprgols based on hydrazine and nitrogen teroxide,HIP_11 pairs hydrogen peroxide with an ionic liquid-based fuel to achieve hypergolic ignition—significantly simplifying handling while ensuring robustness and performance. The unique propellant formulation has already demonstrated critical milestones in multiple ground-based tests, and it continues to attract commercial attention. Notably, The Exploration Company(TEC) has already licensed HIP_11 for use in their Nyx capsule,demonstrating the market’s eagerness for cleaner, more flexible spacecraft propulsion options.
A Solution Tailored for Larger Spacecraft Unlocking a New Level of Mission Flexibility
HIP_11 is suited for all in-space applications where conventional hypergols are used today. From capsules and landers to large satellites, HIP_11 fits a into the market where high thrust, reliability and cost-effectiveness converge.
But HIP_11's true breakthrough lies in its multi-mode capabilities. Our unique propellant combination enables different propulsion modes out of one HIP_11 propulsion system:
Fast maneuvers at high thrust in hypergolic mode Precise hydrogen peroxide in monopropellant operation for delicate maneuvers High-efficiency electric propulsion utilizing the ionic liquid component Dynamic switching between modes for unprecedented mission flexibility With this HIP_11 enables a range of operational scenarios that significantly enhance mission capabilities. The system facilitates high-velocity transfers during time-sensitive mission phases, while also supporting efficient station-keeping operations that maximize operational lifespan. Additionally, its multi-mode functionality provides unprecedented flexibility, allowing to adjust the delta-v even after the spacecraft has been deployed.
