Zusammenfassung:An apparatus for driving a TEF(Trailing Edge Flap) of a manned or unmanned helicopter is provided to reduce the noise and vibration by stably driving the TEF. An apparatus for driving a TEF(30) of a manned or unmanned helicopter comprises a TEF frequency generator(10) and a TEF driver(20). The TEF frequency generator measures the rotor rpm of the manned or unmanned helicopter and generates a base waveform for driving the TEF by converting and amplifying the measured rpm signal. The TEF driver is connected to the TEF frequency generator, converts and amplifies the base waveform from the TEF frequency generator, and drives the TEF base on the converted/amplified signal.
