Abstract

To provide a flying object including a lift generating member deployment device that makes it easier than before to automatically avoid collision with an obstacle. A flying object 30 includes an obstacle detecting unit 5, a control unit 6, a battery 7, a storage unit 8 that stores information transmitted from the control unit 6, a transmitting/receiving unit 9 that receives an operation signal from a controller 40 and transmits information regarding the flying object 30 to the controller 40, and others. The obstacle detecting unit 5 is to detect the altitude of the flying object 30 and outputs an altitude detection signal, which represents the detected altitude information, to the control unit 6. In addition, upon detecting an obstacle present within a predetermined distance, the obstacle detecting unit 5 outputs an obstacle detection signal to the control unit 6, detects the distance between the flying object body 31 and the obstacle, and outputs a distance detection signal, which represents the detected distance information, to the control unit 6. The control unit 6 determines whether or not to actuate left and right brake cord pulling devices 10 in accordance with the signal received from the obstacle detecting unit 5.

First claim

The invention claimed is:

1. A flying object comprising:
a flying object body;
a to-be-deployed object that is disposed in the flying object body and includes a lift generating member and a steering unit capable of steering the lift generating member after deployment via a connecting member connected to the lift generating member;
a wind direction detecting unit that is disposed in the flying object body and detects a wind direction; and,
a control unit that receives, when the wind direction detecting unit detects the wind direction, a wind direction signal including information regarding the wind direction from the wind direction detecting unit;
wherein after the to-be-deployed object is deployed, the control unit performs control to operate the steering unit, as necessary, on a basis of the wind direction signal received from the wind direction detecting unit.

2. The flying object according to claim 1 , further comprising:
a deployment device for the lift generating member, the deployment device being disposed in the flying object body;
wherein the deployment device includes a containing unit that holds the lift generating member being in a closed state, and an ejecting unit that ejects the lift generating member from the containing unit; and,

wherein after the deployment device is actuated, the control unit performs control to operate the steering unit, as necessary, on a basis of the wind direction signal received from the wind direction detecting unit.

3. The flying object according to claim 1 , wherein the wind direction detecting unit detects a wind direction at time intervals of one second or less.

4. The flying object according to claim 1 , wherein the wind direction detecting unit is a weathercock-type wind direction indicator.

5. The flying object according to claim 1 , wherein the wind direction detecting unit includes at least one wind speed meter.

6. The flying object according to claim 1 , wherein the wind direction detecting unit includes a high-rate GPS and a geomagnetic sensor, the high-rate GPS determining positions at a higher rate than a GPS.

7. The flying object according to claim 1 , wherein the wind direction detecting unit includes a GPS, an acceleration sensor, and a compass.
