Abstract

An airport for a vertical take-off and landing aircraft includes three or more windbreak walls that extend radially about a reference axis, and three or more take-off and landing areas for the vertical take-off and landing aircrafts, which are partitioned by two adjacent windbreak walls among the three or more windbreak walls.

Claims (16)

1 . An airport for a vertical take-off and landing aircraft, the airport comprising:

three or more windbreak walls that extend radially about a reference axis;

three or more take-off and landing areas for the vertical take-off and landing aircraft, which are partitioned by two adjacent windbreak walls among the three or more windbreak walls; and

wherein a slit that causes two adjacent take-off and landing areas to communicate with each other is provided at a lower portion of one windbreak wall that partitions the two adjacent take-off and landing areas among the three or more windbreak walls.

2 . The airport for a vertical take-off and landing aircraft according to claim 1 , wherein at least one area of remaining areas excluding an area located on a windward side of the reference axis among the three or more take-off and landing areas is used for take-off and landing of the vertical take-off and landing aircraft.

3 . The airport for a vertical take-off and landing aircraft according to claim 1 , wherein a plurality of remaining areas excluding an area located on a windward side of the reference axis among the three or more take-off and landing areas are used for take-off and landing of the vertical take-off and landing aircraft.

4 . The airport for a vertical take-off and landing aircraft according to claim 1 , wherein an area located most leeward among the three or more take-off and landing areas is used for take-off and landing of the vertical take-off and landing aircraft.

5 . The airport for a vertical take-off and landing aircraft according to claim 1 ,

wherein the three or more windbreak walls are four windbreak walls,

wherein the three or more take-off and landing areas are four take-off and landing areas, and

wherein, among the four take-off and landing areas, an area different from an area located on a windward side of the reference axis, or an area located most leeward among the four take-off and landing areas is used for take-off and landing of the vertical take-off and landing aircraft.

6 . The airport for a vertical take-off and landing aircraft according to claim 1 , wherein a columnar body to which each of the three or more windbreak walls is coupled is provided at a position of the reference axis.

7 . The airport for a vertical take-off and landing aircraft according to claim 1 , wherein the slit has a symmetrical shape with respect to a center plane of one windbreak wall that partitions the two adjacent take-off and landing areas.

8 . The airport for a vertical take-off and landing aircraft according to claim 7 , wherein a shape of the slit in a cross section perpendicular to the center plane of the one windbreak wall is an inverted V-shape.

9 . The airport for a vertical take-off and landing aircraft according to claim 1 , wherein a number of the three or more windbreak walls is any of 3 to 8.

10 . The airport for a vertical take-off and landing aircraft according to claim 1 , wherein at least one area of remaining areas excluding an area located most windward among the three or more take-off and landing areas is used for take-off and landing of the vertical take-off and landing aircraft.
