Engine Test Roundup for Q2 2023

Test data volume and diversity is the key to making rocket propulsion more reliable, accessible, and less expensive. Ursa Major’s facility houses the country’s most efficient propulsion innovation and production ecosystem, with design, engineering, production, and testing in one place.

This spring, we focused on ongoing development testing of the 5,000-pound-thrust Hadley engine. We apply learnings from Hadley’s deep manufacturing and testing heritage to Draper, the 4,000-pound-thrust storable engine we’re developing under a contract with the Air Force Research Laboratory.

The test team executes three tests per day, on average.
