Aircraft
The aircraft includes a fuselage, a front wing and a rear wing provided to extend laterally from the fuselage for generating lift during cruise, a boom 18 supported by the front wing and the rear wing to be spaced apart from the fuselage, and at least one VTOL rotor that is supported on the boom, and having one or more blades for generating thrust in a vertical direction during take-off and landing, wherein the boom has a shape in a top view in which a barrel forms a curvature in a direction away from the fuselage with respect to a front end and a rear end while extending in a front-back direction, and has a cross section in a front view in which an upper side forms a round curvature, the boom being tapered from an upper side from a lower side, and the lower side is substantially flat.
1. An aircraft comprising:
a fuselage;
a wing body that is provided to extend laterally from the fuselage and configured to generate lift during cruise;
a boom that is supported by the wing body to be spaced apart from the fuselage; and
at least one rotor supported on the boom, the at least one rotor having one or more blades configured to generate thrust in a vertical direction during take-off and landing, wherein
the boom has a shape in a top view in which a barrel forms a curvature in a direction away from the fuselage with respect to a front end and a rear end while extending in a front-back direction, and has a cross section in a front view in which an upper side forms a round curvature, the boom being tapered from the upper side from a lower side, and the lower side is substantially flat.
2. The aircraft according to claim 1 , wherein the boom is configured to store a rotational apparatus for rotating the one or more blades of the at least one rotor and a radiator for cooling the rotational apparatus, and includes a raised-bottom portion having a lower end thereof positioned on an upper side with respect to an storage portion for storing the radiator.
3. The aircraft according to claim 2 , wherein the raised-bottom portion is positioned at least at a center of the barrel forming a curvature with respect to the front end and the rear end of the boom.
4. The aircraft according to claim 2 , wherein the raised-bottom portion is positioned at least at a front side of the barrel forming a curvature with respect to the front end and the rear end of the boom.
5. The aircraft according to claim 2 or 3 , wherein the raised-bottom portion is positioned at least at a front side of the barrel forming a curvature with respect to the front end and the rear end of the boom.
6. The aircraft according to claim 2 , wherein the boom has a shape in which an upper end of a rotor position for storing the rotational apparatus is positioned on an upper side with respect to the storage portion.
7. The aircraft according to claim 3 , wherein the boom has a shape in which an upper end of a rotor position for storing the rotational apparatus is positioned on an upper side with respect to the storage portion.
8. The aircraft according to claim 2 , wherein
the boom is configured to store four rotational apparatuses for rotors at a first rotor position, a second rotor position, a third rotor position, and a fourth rotor position arranged from front to back, respectively, and
the storage portion includes a first storage portion positioned at a rear side of the first rotor position and a second storage portion positioned at a rear side of the third rotor position.
9. The aircraft according to claim 3 , wherein
the boom is configured to store four rotational apparatuses for rotors at a first rotor position, a second rotor position, a third rotor position, and a fourth rotor position arranged from front to back, respectively, and
the storage portion includes a first storage portion positioned at a rear side of the first rotor position and a second storage portion positioned at a rear side of the third rotor position.
10. The aircraft according to claim 8 , wherein the raised-bottom portion is positioned between the second rotor position and the third rotor position.
11. The aircraft according to claim 8 , wherein the raised-bottom portion is positioned at a front side of the second rotor position.
12. The aircraft according to claim 10 , wherein the raised-bottom portion is positioned at a front side of the second rotor position.
13. The aircraft according to claim 8 , wherein the boom has a smaller width than the storage portion at an inter-rotor portion that does not include the storage portion among inter-rotor portions between the first rotor position through the fourth rotor position.
14. The aircraft according to claim 10 , wherein the boom has a smaller width than the storage portion at an inter-rotor portion that does not include the storage portion among inter-rotor portions between the first rotor position through the fourth rotor position.
15. The aircraft according to claim 2 , wherein a lower end of the boom is tilted from the storage portion to the raised-bottom portion.
16. The aircraft according to claim 3 , wherein a lower end of the boom is tilted from the storage portion to the raised-bottom portion.
17. The aircraft according to claim 1 , wherein the boom has a shape in which the front end forms a round curvature and the rear end is tapered.
18. The aircraft according to claim 2 , wherein the boom has a shape in which the front end forms a round curvature and the rear end is tapered.
19. The aircraft according to claim 1 , further comprising a cruising rotor that is provided at a rear end of the fuselage, the cruising rotor having one or more blades for generating thrust during cruise.
