Abstract

A flying object 20 is provided with a rotor blade 200 that generates lift and thrust by rotating and a rotating electrical machine unit that rotates the rotor blade 200 . The rotor blade 200 receive wind power and rotate when not flying. The rotating electrical machine unit generates electric power based on a power that rotates the rotor blades 200 when not flying. In addition, the flying object 20 may be provided with a power storage device 230 that stores electric power generated by the rotating electrical machine unit. In addition, the flying object 20 may be provided with a detachably connected cartridge 260 that has a desired function.

First claim

The invention claimed is:

1. A flying object system comprising:
a flying object; and
a master unit configured to be detachably connectable with the flying object,
wherein the flying object comprises:
a rotor blade configured to generate lift or thrust by rotating; and
a rotating electrical machine unit configured to rotate the rotor blade,

wherein the rotor blade is configured to receive wind power and rotate when not flying,
wherein the rotating electrical machine unit is configured to generate electric power based on a power that rotates the rotor blade when not flying,
wherein the master unit comprises a departure/arrival device configured to rotate the flying object around an axis in a horizontal direction,
wherein the departure/arrival device comprises a departure/arrival platform configured to fix the flying body, and a rotating device whose one end is rotatably connected to the departure/arrival platform,
wherein the master unit comprises a swing device configured to rotate in a circumferential direction around a vertical axis passing through a center of the master unit, and is configured to rotate so that the longitudinal direction of the departure/arrival device is perpendicular to the wind direction, and
wherein the departure/arrival device is configured to:
allow, when the rotating electrical machine unit generates electric power, the rotating device to rotate the departure/arrival platform around an axis in a longitudinal direction of the departure/arrival device, and make a rotation axis direction of the rotor blade rotate in a direction in which the rotor blade receives the wind power and rotate; and
make, when the flying object takes off, the rotation axis direction rotate in a direction in that the flying object takes off.

2. The flying object system according to claim 1 ,
wherein the master unit comprises a master unit power storage device configured to store electric power generated by the rotating electrical machine unit.

3. The flying object system according to claim 1 ,
wherein the flying object comprises a detachably connected cartridge configured to have a desired function, and
wherein the master unit comprises a cartridge replacing device configured to replace the cartridge.

4. The flying object according to claim 3 , further comprising a processor,
wherein the cartridge comprises a storage device configured to store a program, and
wherein the processor is configured to execute the program stored in the storage device.

5. The flying object according to claim 3 , wherein the cartridge comprises a sensor configured to measure meteorologic information or oceanographic information.

6. The flying object according to claim 3 , wherein the cartridge comprises a sonic sensor.

7. The flying object according to claim 1 , further comprising a power storage device configured to store electric power generated by the rotating electrical machine unit.

8. The flying object according to claim 1 ,
wherein the rotating electrical machine unit comprises a rotating electrical machine, and
wherein the rotating electrical machine is configured to:
rotate the rotor blade; and
generate electric power based on the power that rotates the rotor blade.

9. The flying object according to claim 1 ,
wherein the rotating electrical machine unit comprises:
an electric motor configured to rotate the rotor blade; and
a generator, that is different from the electric motor, configured to generate electric power based on the power that rotates the rotor blade.
