An example system includes a first gas-turbine engine configured to propel an aircraft, the first gas-turbine engine comprising: a first air-turbine starter, the first air-turbine starter configured to rotate a spool of the first gas-turbine engine; and a ...

A computer-implemented method includes determining a thrust requirement to satisfy a desired glide slope and determining, based on the thrust requirement, whether thrust matching can be maintained while operating a first gas turbine engine in a fuel-burnin...

A method is disclosed for controlling gas turbine operation in response to lean blowout of a combustion can (14,15). The gas turbine (16) comprises a pair of combustion cans (14,15). The method includes sensing that a first combustion can (14) is extinguis...

A stall detection and recovery system (10) for a gas turbine engine (1) comprises surge detection means (50 for detecting an engine surge and providing a surge detection signal (154) for indicating said engine surge. The system also includes stall detectio...

A flameout detection system (50) for an engine that facilitates detection of flameout (58) in the engine in a cost-effective and reliable manner is described. A method implemented by the device includes the steps of detecting a rate of change of gas genera...
