Study Notes
Power Transmission Overview
- Engine power is combined in the main gearbox (MGB) for transmission to the main rotor.
- The tail rotor drive shaft is powered by the MGB, using flexibly coupled shafts.
Gearbox Configuration
- The transmission system includes:
- Main Gear Box (MGB)
- Auxiliary Gear Box
- Intermediate Gear Box
- Tail Gear Box
- Tail Drive Shaft
- Anti-Resonance Isolation System (ARIS)
Accessory Drives
- Power from the MGB drives various accessories on the left-hand (LH) and right-hand (RH) sides, including:
- Hydraulic pump
- Alternator
- Lubricating pump
Other Key Points
- The transmission arrangement is complex, ensuring efficient power distribution across various components.
- Each subsystem plays a critical role in maintaining functionality and stability in rotor operations.
