The BOLE booster, designed to support manned space missions to the Moon and beyond, completed its first full-scale static ignition test, marking a breakthrough in the development of solid propulsion systems. For more than two minutes, the 47-meter-long rocket generated more than 1,800 tons of thrust, validating key components under extreme conditions.
A new design for the BOLE solid rocket engine
The BOLE (Booster Obsolescence and Life Extension) integrates significant advances over its SLS (Space Launch System) predecessor, including a carbon fiber casing and an optimized propellant formula. These changes allow for a greater than 10% increase in performance, according to preliminary data collected by the more than 700 sensor channels installed for the test.
[post_relacionado]Northrop Grumman is committed to a domestic supply chain. The propellant includes metal components manufactured by local companies, aligning its manufacture with commercial standards. The composite structure not only improves the spacecraft’s efficiency, it also spacecraftbut also reduces production times.
Direct impact on lunar missions
Compared to the previous engine of the SLSthe BOLE will be able to carry an additional five metric tons of payload to lunar orbit. This leap in capability is crucial to support the future stages of the Artemis program program and possible missions to Mars.
Although the test exceeded performance targets, a minor anomaly was recorded at the end of ignition. Jim Kalberer, vice president of propulsion systems of Northrop Grumman, noted that analysis of this data will enable design improvements in subsequent phases.
With decades of experience in the aerospace industry and a focus on sustainable standards, Northrop Grumman is consolidating its role as a key player in the advancement of manned space exploration.
