Abstract
An aircraft includes a plurality of takeoff and landing rotors each generating a first airflow below the takeoff and landing rotor, and a cruise rotor generating a second airflow behind the cruise rotor, the plurality of takeoff and landing rotors including a rear rotor disposed behind the cruise rotor. The aircraft further includes an airflow deflection mechanism capable of changing a direction of the second airflow, and a controller for controlling the airflow deflection mechanism to suppress interference between the first airflow generated by the rear rotor and the second airflow.
Claims5
An aircraft comprising:
- a fuselage;
- a wing connected to the fuselage;
- a plurality of takeoff and landing rotors each configured to generate a first airflow below the takeoff and landing rotor in order for the aircraft to perform vertical movement;
- a cruise rotor configured to generate a second airflow behind the cruise rotor in order for the aircraft to perform forward movement,
- the plurality of takeoff and landing rotors including a rear rotor disposed behind the cruise rotor,
- the aircraft further comprising:
- an airflow deflection mechanism configured to change an azimuth of the second airflow with respect to an axial direction of the fuselage in a plan view;
- and
- a controller configured to control the airflow deflection mechanism to suppress interference between the first airflow generated by the rear rotor and the second airflow during at least one of a transition from the vertical movement to the forward movement or a transition from the forward movement to the vertical movement, wherein
- the rear rotor is disposed so as to be separated from an axis of the fuselage in one of left and right directions by a first distance,
- the cruise rotor is disposed so as to be separated from the axis of the fuselage in the one of the left and right directions by a second distance smaller than the first distance, and
- the controller is configured to:
- control the airflow deflection mechanism to increase the azimuth of the second airflow with respect to the axial direction of the fuselage when suppressing the interference between the first airflow and the second airflow;
- and
- control the airflow deflection mechanism to decrease the azimuth of the second airflow with respect to the axial direction as a speed of the forward movement increases.
