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.

ExpandingMomentum Through FLPP-FIRST!Propulsion

The FLPP-FIRST!Propulsion project NewSTyLE aims to elevate HIP_11’s readiness for space applications. This progress builds on earlier successful demonstrators and further cements HIP_11’s viability as a high-performance propulsion alternative.
