Abstract (en)
A gas turbine engine includes an annular first combustor assembly (5) and a second combustor assembly (8). At least three flame detectors (18) are arranged to monitor flame presence in the first combustor assembly (5) and supply respective flame monitoring signals (SFM1, SFM2, SFM3) indicating flame presence. A temperature monitoring assembly (20), detects a control temperature (TC) of hot gas flowing from the first combustor assembly (5) to the second combustor assembly (8) downstream of the first combustor assembly (5). A processing unit (17) determines dangerous flame failure based, at least in a control range of operating conditions, on the flame monitoring signals (SFM1, SFM2, SFM3) and a control function of the control temperature (TC) and based on M-out-of-N activation redundancy with Hardware Failure Tolerance of at least 1, wherein M is at least 3 and N is at least 4.
