1. An aircraft comprising:
a fuselage having a main wing at opposite sides and elongated along a longitudinal direction of the fuselage;
a first nozzle disposed on a roof of the fuselage and elongated along the longitudinal direction of the fuselage;
a plurality of second nozzles disposed on an upper surface of the main wing along a longitudinal direction of the main wing;
a first tank disposed in the fuselage or the main wing and configured to store first compressed air; a main control valve configured to provide the first compressed air to the first nozzle or the plurality of second nozzles;
a second tank configured to store second compressed air;
a pressure reducing valve configured to reduce a pressure of the second compressed air of the second tank and coupled to the first tank;
a first pitching nozzle disposed on a lower front side of the fuselage and configured to spray the first compressed air in a downward direction;
a second pitching nozzle disposed on a lower rear side of the fuselage and configured to spray the first compressed air in the downward direction;
a first rolling nozzle disposed at a right end of the main wing and configured to spray the first compressed air in the downward direction;
a second rolling nozzle disposed at a left end of the main wing and configured to spray the first compressed air in the downward direction;
a first yaw nozzle disposed at a right end of main wing and configured to spray the first compressed air in a backward direction; and
a second yaw nozzle disposed at a left end of the main wing and configured to spray the first compressed air in the backward direction,
wherein a pressure of the first compressed air is lower by a predetermined amount compared to the pressure of the second compressed air.
