Abstract

Flight equipment according to an embodiment of the present invention includes: an aerial vehicle having a body and at least one rotor held on the body; a plurality of supporters mounted to the aerial vehicle and supporting a protective member stretched therebetween so as to surround an outside of the body; a support information detection unit configured to detect support information indicating a support state of the protective member; and a mounting state determiner configured to determine whether the support state of the protective member is suitable or unsuitable, based on a value detected by the support information detection unit.

Claims (56)

1. Flight equipment comprising:

an aerial vehicle having a body and at least one rotor held on the body;

a plurality of support structures mounted to the aerial vehicle and configured to support a protective member stretched therebetween so as to surround an outside of the body and the at least one rotor;

a support information detection circuitry configured to detect support information indicating a support state of the protective member; and

mounting state determination circuitry configured to determine whether the support state of the protective member is suitable or unsuitable, based on the support information.

2. The flight equipment according to claim 1 , wherein

the support information detection circuitry comprises a sensor applied to the protective member.

3. The flight equipment according to claim 2 , wherein

the sensor comprises a strain sensor configured to detect deformation of one of the plurality of support structures.

4. The flight equipment according to claim 3 , wherein

one of the plurality of support structures comprises:

a fastenable structure mounted to the aerial vehicle and extending substantially perpendicularly to a rotation axis of the at least one rotor; and

an extension structure attached to a distal end portion of the fastenable structure and extending substantially parallel to the rotation axis of the at least one rotor, and

the strain sensor is arranged on the extension structure.

5. The flight equipment according to claim 3 , wherein

the strain sensor comprises a plurality of strain sensors that are arranged on the plurality of support structures on a one-to-one basis.

6. The flight equipment according to claim 5 , wherein

the mounting state determination circuitry is further configured to determine that the support state of the protective member is unsuitable when a difference between a maximum and a minimum of values detected by the support information detection circuitry exceeds a preset threshold.

7. The flight equipment according to claim 1 , wherein

the mounting state determination circuitry is arranged on the plurality of support structures.

8. The flight equipment according to claim 1 , further comprising:

an annunciator configured to announce information corresponding to a determination result of the mounting state determination circuitry.

9. The flight equipment according to claim 8 , wherein

the annunciator is configured to announce the information such that it is identifiable which of the plurality of support structures supports the protective member in the unsuitable support state.

10. The flight equipment according to claim 1 , further comprising:

a takeoff controller configured to determine whether to permit takeoff of the flight equipment, based on a determination result of the mounting state determination circuitry.

11. A flight system comprising:
