Adaptive acceleration schedules for gas turbine engine control systems

摘要

Disclosed is an engine surge avoidance system and method which adapts the acceleration schedules (i.e., P2.5 bleed valve and NDOT) to prevent engine surge events from occurring while minimizing reductions in engine response time. The surge avoidance system and method disclosed herein achieves this goal by adapting both the NDOT and the P2.5 bleed schedules in an optimum fashion.
