Abstract

A delivery rotary-wing aircraft has a plurality of rotary wings, a central portion to which a plurality of arms for supporting the rotary wings are connected, a first mounting portion for loading a package, a second mounting portion which is located on the opposite side to the first mounting portion as viewed from the central portion, a first supporting member for coupling the first mounting portion with the central portion, and a connection portion between the central portion and the first supporting member. The center point of lift occurring in the rotary-wing aircraft with the rotation of the plurality of rotary wings and the center point of gravity of the rotary-wing aircraft coincide with the center point of the connection portion. The first supporting member is equipped with an adjustment mechanism for vertically downwardly extending the length of the first supporting member.

First claim

1 - 5 . (canceled)

6 . A delivery rotary-wing aircraft comprising:
a plurality of rotary wings, a central portion to which a plurality of arm portions for supporting the rotary wings are connected, a first mounting portion for loading a package, a second mounting portion which is located on the opposite side to the first mounting portion as viewed from the central portion, a first supporting member for connecting the first mounting portion with the central portion, and a connection portion between the central portion and the first supporting member, characterized by being controlled in such a manner that the center point of lift occurring in the rotary-wing aircraft with rotations of the plurality of rotary wings and the center point of gravity of the rotary-wing aircraft coincide with the center point of the connection portion, and the first supporting member is equipped with an adjustment mechanism for vertically downwardly extending the length of the first supporting member.

7 . The delivery rotary-wing aircraft according to claim 6 , characterized in that the first supporting member comprises an outer cylindrical supporting member and an inner cylindrical supporting member,
the inner cylindrical supporting member is accommodated in the outer cylindrical supporting member, and the inner cylindrical supporting member slides downward to thereby vertically downwardly extend the length of the first supporting member.

8 . The delivery rotary-wing aircraft according to claim 6 ,
characterized in that the second mounting portion has a control means which measures the acceleration at the time of landing of the rotary-wing aircraft or the numbers of rotations of the plurality of rotary wings, and changes the numbers of revolutions of the plurality of rotary wings against the vertically upward updraft applied to the rotary-wing aircraft.

9 . The delivery rotary-wing aircraft according to claim 7 ,
characterized in that the second mounting portion has a control means which measures the acceleration at the time of landing of the rotary-wing aircraft or the numbers of rotations of the plurality of rotary wings, and changes the numbers of revolutions of the plurality of rotary wings against the vertically upward updraft applied to the rotary-wing aircraft.

10 . The delivery rotary-wing aircraft according to claim 6 ,
characterized in that the first supporting member has a joint portion between the connection portion and the first mounting portion.

11 . The delivery rotary-wing aircraft according to claim 7 ,
characterized in that the first supporting member has a joint portion between the connection portion and the first mounting portion.

12 . The delivery rotary-wing aircraft according to claim 8 ,
characterized in that the first supporting member has a joint portion between the connection portion and the first mounting portion.

13 . The delivery rotary-wing aircraft according to claim 9 ,
characterized in that the first supporting member has a joint portion between the connection portion and the first mounting portion.

14 . The delivery rotary-wing aircraft according to claim 10 ,
characterized in that, when the rotary-wing aircraft moves in the horizontal direction, the first supporting member is horizontally positioned by bending the first supporting member in the traveling direction with the joint portion as a fulcrum.

15 . The delivery rotary-wing aircraft according to claim 11 ,
characterized in that, when the rotary-wing aircraft moves in the horizontal direction, the first supporting member is horizontally positioned by bending the first supporting member in the traveling direction with the joint portion as a fulcrum.

16 . The delivery rotary-wing aircraft according to claim 12 ,
characterized in that, when the rotary-wing aircraft moves in the horizontal direction, the first supporting member is horizontally positioned by bending the first supporting member in the traveling direction with the joint portion as a fulcrum.

17 . The delivery rotary-wing aircraft according to claim 13 ,
characterized in that, when the rotary-wing aircraft moves in the horizontal direction, the first supporting member is horizontally positioned by bending the first supporting member in the traveling direction with the joint portion as a fulcrum.
