How microscopic manufacturing flaws can trigger a catastrophic rocket engine failure
A routine rocket engine test ends in a dramatic explosion. This video examines the forensic investigation into why the combustion chamber failed, revealing how tiny defects introduced during 3D printing led to a total structural collapse on the test stand.
The failure centered on a combustion chamber crafted from GRCop-42 copper alloy using additive manufacturing. Researchers discovered that the explosion was not a random accident but the direct result of quality control issues during the build process.
Specifically, the study highlights how build interruptions created microscopic defects within the material. These structural weaknesses compromised the integrity of the engine, leading to its destruction during testing. The analysis, authored by Gabriel Demeneghi, Benjamin Williams, Colton Katsarelis, and William Tilson, underscores the critical importance of precision in modern aerospace manufacturing.
