A current sensor assembly includes a housing; a plurality of shields which are accommodated inside the housing and open toward the top of the housing; a plurality of bus bars to which three-phase current is applied and which are arranged spaced apart from each other so as to go past the plurality of shields, respectively; and a current sensor unit which includes a printed circuit board and a plurality of current sensors disposed on the printed circuit board to measure the current applied to the bus bars. The shields, the bus bars, and the current sensor unit are configured to be accommodated inside the housing, and the current sensors are spaced apart from the bus bars and disposed in the inner spaces of the shields.

A vertical take-off and landing aircraft using a hybrid electric propulsion system includes an engine, a generator that produces electric power using power supplied by the engine, and a battery that stores the produced electric power. A motor receives the electric power stored in the battery and electric power produced by the generator but not stored in the battery and provides the power to a thrust generating apparatus. A controller selects either silence mode or normal mode, and determines the amount of electric power stored in the battery and the amount of electric power not stored in the battery from the electric power supplied to the motor. In the silence mode, the controller supplies only the electric power stored in the battery and controls a duration by adjusting output power of motor. In the normal mode, the controller supplies electric power not stored in the battery.
