Mechanism and experiments

FLARE coordinates two snake robots: one supports visual observation and the other applies flame-sprayed material to patch the ceramic thermal-barrier coating on a combustor liner. Rolls-Royce’s 2019 report and video document laboratory tests in an actual engine.

Test conditions and scope

The source documents laboratory engine tests, without an airworthiness approval or fleet-service record.
