Ursa Major's Hadley H13 Engine: A New Benchmark in Rocketry

Ursa Major, an innovative aerospace company based in Berthoud, Colorado, has unveiled the latest iteration of its Hadley liquid rocket engine: the Hadley H13. This new model builds upon the proven technology of its predecessor, the Hadley H11, and introduces several enhancements that solidify its standing as a leader in the hypersonic and launch vehicle market.

Key Features of the Hadley H13

The Hadley H13 engine successfully completed its first hot fire tests, demonstrating the efficacy of recent design improvements and manufacturing process optimizations. Unlike earlier versions, the H13 is designed explicitly for hypersonic applications and features increased reusability—boasting the ability to be reused more than twice as frequently as prior models. This breakthrough is expected to significantly drive down costs per flight, making it an attractive option for a variety of space missions.

Chris Spagnoletti, CEO of Ursa Major, emphasizes the engine's foundational role within the company's lineup, highlighting its historical success in hypersonic flight. He noted that new materials utilized in the H13 enhance performance and longevity. By bringing many components of the engine in-house, Ursa Major has implemented vertical integration of additively manufactured parts, leading to cost efficiencies and more streamlined production.

Overcoming Previous Limitations

Historically, the Hadley engine required custom solutions that extended development timelines. The H13 addresses this issue by productizing the engine for multiple applications, effectively reducing lead times associated with engine deployment. This strategic shift positions the Hadley H13 as an off-the-shelf option for urgent launch needs, supporting various mission profiles in hypersonic flight and beyond.

The engine's design utilizes cryogenic fuels, making it the most cost-effective and high-performing rocket engine developed by Ursa Major to date. The Hadley H13 delivers an impressive thrust of 5,000 pounds at sea level, which can be increased to 6,500 pounds in its vacuum variant—it is notably the first American-built propulsion engine to achieve sustained speeds exceeding Mach 5 and return safely, as demonstrated with its successful integration into Stratolaunch's Talon-A vehicle.

A New Standard for Rocketry

With 80% of its components manufactured through additive processes, the Hadley engine sets new benchmarks in production efficiency. This degree of manufacturing innovation allows for rapid iteration, minimal part counts, and accelerated timelines for operational readiness. Such advancements not only benefit the company’s bottom line but also ensure that Ursa Major remains competitive in a rapidly evolving market.
