QuesTek publishes research on materials design for reusable rocket engines

QuesTek Innovations announced peer-reviewed research on July 21, 2026, showing how its computational materials approach can speed development of a nickel-based superalloy for reusable rocket engines. The study highlights how predictive design could help engineers balance strength, burn resistance and printability for next-generation propulsion systems.

Why it matters: - Reusable rocket engines need materials that can handle extreme heat, oxygen-rich combustion environments and additive manufacturing. - The research points to a faster way to design those materials before costly physical testing begins. - The same approach could also apply to defense, energy, transportation and other industries that face competing performance requirements.

What happened: - QuesTek Innovations announced the publication of a peer-reviewed research article on July 21, 2026. - The paper was published in the Journal of Materials Engineering and Performance. - The article is titled Using ICME to Design a Novel High-Strength, Printable, and Burn-Resistant Nickel-Based Superalloy for Reusable Rocket Engines. - Gary Whelan and Abhinav Saboo authored the study. - The research presents Sunaloy, a novel nickel-based superalloy developed for reusable rocket engines.

The details: - The study uses Integrated Computational Materials Engineering, or ICME, to accelerate materials development for rocket propulsion. - QuesTek’s Materials by Design® technology, delivered through the ICMD® software platform, was used to computationally evaluate material design challenges before production. - The approach combines physics-based models to design and optimize Sunaloy. - The research targets three competing requirements: high strength, resistance to burn in oxygen-rich environments and compatibility with additive manufacturing. - Conventional development for this kind of material has relied on extensive testing and iterative experimentation. - The full paper is available through Springer Nature. - QuesTek says its Materials by Design® technology and ICMD® platform reduce development time and cost while improving material performance. - QuesTek says it is the first provider in its market space to complete the full cycle from novel design to production, certification and flight operations with proprietary materials. - Fast Company named QuesTek a 2025 Most Innovative Company.

Between the lines: - The research is not just about one alloy. It is a demonstration of a broader design workflow that shifts materials development earlier in the engineering process. - That matters because reusable launch systems raise the bar on performance while also increasing pressure to cut development time. - Whelan framed the work as a way to let engineers create application-specific materials instead of choosing from existing material tables.

What's next: - QuesTek says the same computational approach can be applied beyond aerospace. - The company points to possible use across defense, energy, additive manufacturing, transportation and other sectors. - The publication gives engineers and potential customers a peer-reviewed example of how ICME can support next-generation materials design.

The bottom line: - QuesTek is positioning predictive materials design as a practical tool for building rocket-engine materials that are stronger, more printable and more resistant to burn out.
