Each accessory module drives both which two components?

Each accessory module drives both which two components?

• A. Hydraulic Pump and Main Generator
• B. Main Generator and Hydraulic Pump
• C. Electrical Bus and Hydraulic Pump
• D. Main Generator and Cooling Fan

Answer: (B)

In the UH-60S, each accessory module is driven by the engine and provides power to two key devices: the main generator and the hydraulic pump. The main generator supplies electrical power to the helicopter’s electrical buses and systems, while the hydraulic pump delivers the hydraulic pressure needed for flight control and other hydraulics. These two loads are the primary outputs of the accessory drive, so both are driven by the same accessory module. The electrical bus itself is fed from the generator and then distributed, and the cooling fan is driven through other paths in the engine/gearbox system rather than directly by the accessory module.
