Renton, Washington Patent of the Year – 2024/2025
Radian Aerospace Inc. has been awarded the 2024/2025 Patent of the Year for innovation in spaceflight propulsion. Their invention, detailed in U.S. Patent No. 11920543, titled ‘Rocket propulsion systems and associated methods’, introduces a next-generation engine design aimed at revolutionizing reusable space vehicles.
This breakthrough system enhances efficiency, reduces turnaround time, and supports rapid reuse of launch vehicles. By integrating streamlined engine components with simplified operational methods, the design allows for smoother transitions between different stages of flight. The innovation boosts performance while minimizing wear, making frequent flights more practical and cost-effective.
Unlike conventional rocket systems, Radian’s approach focuses on horizontal takeoff and landing. This unique architecture demands propulsion solutions that balance thrust, control, and reusability. The patented system helps meet those needs by supporting precise, responsive flight control and reducing dependence on complex ground infrastructure.
Radian Aerospace Inc. is developing a fully reusable spaceplane capable of taking off from runways and reaching orbit in a single stage. This patent marks a critical step toward realizing that vision. As the race for lower-cost space access accelerates, innovations like this could shift the industry toward faster, safer, and more sustainable missions. With this award-winning design, Radian brings the future of spaceflight a step closer to reality.
