During a rapid acceleration the compressor working line

  • A.Moves towards the surge line
  • B.Moves away from the surge line
  • C.Stays exactly where it was
  • D.Moves towards the choke line

Answer: A

Fuel is added faster than the shaft can accelerate, so the pressure ratio rises before the flow has risen to match. The fuel control schedules acceleration precisely to keep that transient excursion within the available surge margin.
