Propeller control system of air mobility

A propeller control system of an air mobility, the propeller control system comprising:

• a driving shaft connected to a driving motor to be rotated;
• a rotary shaft connected to the driving shaft via a first clutch to be rotated with the driving shaft according to whether the first clutch is engaged;
• a fixed part extending from the rotary shaft, having an internal space formed in the fixed part, and forming a shape of part of a propeller;
• a movable part provided to be withdrawn from or inserted into the internal space of the fixed part, and forming a shape of the remainder of the propeller when withdrawn from the fixed part;
• a pulley mechanism connected to the driving shaft and connected to the movable part through the fixed part;
• and
• a control part configured to determine whether the movable part is inserted or withdrawn, and to control the first clutch to be disengaged when the movable part is inserted, such that the movable part connected to the pulley mechanism is inserted into the fixed part as the driving shaft and the pulley mechanism other than the rotary shaft are rotated by the driving motor,
• wherein the driving shaft and the pulley mechanism are connected via a second clutch, and the driving shaft and the pulley mechanism are rotated together according to whether the second clutch is engaged.
