Engine: Gas Turbines

1. A Direct air flow to each rotor stage at the correct angle and deliver air to the combustor at the correct velocity and pressure.
2. B Direct air flow to rotor blades at the correct angle and are shaped to produce a velocity increase and maintain a constant pressure.
3. C Direct air flow to rotor blades at the correct angle and are shaped to cause a velocity increase and a pressure decrease.
4. D Direct air flow to rotor blades at the correct angle and are shaped to maintain a constant velocity and produce a pressure increase.
