Module 17. Propeller
A propeller synchronising system allows a pilot to reduce noise and vibration by
•  adjusting the phase angle between the propellers.
•  setting the RPM of all propellers exactly the same.
•  adjusting the plane of rotation of all propellers.

Module 15. Gas turbine engine
An exhaust cone placed aft of the turbine in a jet engine will cause the pressure in the first part of the exhaust duct to
•  increase and the velocity to decrease.
•  decrease and the velocity to increase.
•  increase and the velocity to increase.

Ekio asking:
•  The type of duct that forms the exhaust cone will determine what happens with the pressure and temperature. I distinguish 2 types of cone and therefore 2 types of conduit:

1 / convergent - divergent
2 / divergent
