Final answer:
The N2 compressor drives the accessory gear box, which in turn powers many critical aircraft systems such as alternators, hydraulic pumps, and air conditioning units.
Step-by-step explanation:
The N2 compressor in an aircraft is typically part of the engine, and its primary function is to supply energy to various components of the plane. The N2 compressor drives the accessory gear box (AGB), which in turn is responsible for powering many critical aircraft systems.
The N2 compressor and the AGB collectively drive systems such as the engine's alternators, hydraulic pumps, and air conditioning units, among others. These systems are essential for the aircraft's operation, and the efficient working of the N2 compressor and AGB ensures that these systems receive the power they need.
The mechanics of how the AGB interfaces with these systems are based on mechanical linkages and gears that transfer the rotational energy from the engine's N2 spool (the inner shaft) to the various accessories.
