AMP 221 TURBINE THEORY FINAL EXAM STUDY GUIDE When an engine with a subsonic divergent type inlet duct is running in place at high speed on the ground, the air pressure within the inlet is Positive What will result if an oil filter becomes completely blocked? Oil will flow at the normal rate through the system. Why are turbine engine igniters less susceptible to fouling than reciprocating engine spark plugs? The high-intensity spark cleans the igniter. For what primary purpose is a turb...
