Turbine engine control with electronic and pneumatic governors

摘要: A turbine engine (49) fuel delivery system of the type including a pneumatic governor has an electronic and excess stress avoidance feature which disable (70) so long as speed exceeds prescribed value control unit (45) continues to function properly. The transfers governing responsibility controls torque motor solenoid valve diversion line (22). monitors operating parameter such gas generator (37), power speed, output torque, or temperature further diminishes flow when monitored threshold value. resumes normal governoring that returns acceptable level. also senses rotor blade pitch reduce droop increases (44) increases, decreasing decreases.
