Blending Wf/P3 ratio and N-dot fuel commands stabilizes gas turbine startup and thrust increases while avoiding hanging acceleration.
A blended Wf/P3 ratio and N-dot fuel command prevents hanging accelerations while preserving safety limits and repeatable gas turbine response.
A two-step IGV and fuel-rate strategy keeps exhaust flow uniform to protect SCR operation and maintain emissions compliance at low gas turbine loads.
Automatic misaligned power control shifts load after one rotorcraft engine fails, holding rotor speed and limiting emergency power use.
