What critical function does a generator perform in a helicopter's electrical system?

The critical function of a generator in a helicopter's electrical system is to provide a continuous supply of electrical power to operate the helicopter's various electrical components and to recharge the battery. Helicopters rely on electrical power to operate essential systems such as avionics (navigation and communication equipment), lighting, flight control systems, anti-ice systems, and engine starting. The generator, driven by the engine, converts mechanical energy into electrical energy. This electrical energy is used to power these systems while the engine is running. The generator also charges the battery, which is used to start the engine and to provide a backup source of power in case of generator failure. Without a functioning generator, the helicopter would quickly deplete its battery and lose the ability to operate critical electrical systems, potentially leading to a dangerous situation. The generator's output is carefully regulated to maintain a consistent voltage and prevent damage to sensitive electrical components.
