Tell me about the propeller on the Seminole
- Constant speed
- Variable pitch (Governor)
- Full Feathering (low rpm, high pitch) in 6 seconds
- Anti-feathering pins
- Hydraulically Actuated
How does the prop maintain a constant speed?
- Pitch is changed by The Prop. Lever
- The prop lever changes pressure on the Speeder Spring, and tension on the Flyweights
- Change in tension causes the Pilot Valve to move
- This allows oil to move to/from the Prop Hub through the governor
