Topic :  17.4 Propeller Synchronising.



Question Number   1.	Synchrophasing reduces vibration by the use of.		
Option A.   	pulse probes and a single synchrophase unit.	
Option B.   	tachometers and correction motors.	
Option C.   	coordinating the rpm of each engine.	
Correct Answer is.	pulse probes and a single synchrophase unit.	
Explanation.	Refer Jepperson Aircraft Propellers and Controls Page 134.		


Question Number   2.	Synchronising can only be achieved if the slave propeller is.		
Option A.   	the same speed as the master.	
Option B.   	within 20 rpm of the master.	
Option C.   	within 100 rpm of the master.	
Correct Answer is.	within 100 rpm of the master.	
Explanation.	Jepperson Aircraft Propellers and Control page 132 refers.		


Question Number   3.	Synchronising is carried out to.		
Option A.   	match propeller tip speed.	
Option B.   	match engine rpm.	
Option C.   	match blade phase angle difference.	
Correct Answer is.	match propeller tip speed.	
Explanation.	Jepperson Aircraft Propellers and Control page 132 refers.		


Question Number   4.	The synchronisation governor monitors.		
Option A.   	RPM.	
Option B.   	propeller tip speeds.	
Option C.   	thrust tip speeds.	
Correct Answer is.	RPM.	
Explanation.	Jepperson Aircraft Propellers and Controls Page 37 refers.		


Question Number   5.	Synchronisation is used to.		
Option A.   	reduce vibration and noise.	
Option B.   	reduce the pitch of the fastest running blade.	
Option C.   	preset the phase angle of propellers.	
Correct Answer is.	reduce vibration and noise.
