PROBLEM TO BE SOLVED: To provide an unmanned airplane which emits an alarm signal upon an accident and imparts safety to people on the external part.SOLUTION: An alarm device such as buzzer is attached to an unmanned airplane and, when abnormality occurs, informs surrounding people of the abnormality. When the unmanned airplane is joined with a wireless control device, the unmanned airplane is arranged such that the alarm device can be controlled from the wireless control and, when an operator senses abnormality, the unmanned airplane is arranged such that the alarm device can be actuated. Further, when a barometer, an altimeter, a speed meter, etc. are arranged on the unmanned airplane and the unmanned airplane loses height with an abnormal speed, the unmanned airplane is arranged such that the alarm device is automatically actuated. Therein, when the unmanned airplane does not follow the control device, a device which can sense an abnormal behavior of the unmanned airplane, or a device which can sense that numerical values of the barometer, altimeter, etc. do not accord with indication of the control side is arranged and, when it is judged that the unmanned airplane is abnormal, the unmanned airplane is arranged such that the alarm device is actuated. Furthermore, a parachute is arranged on the unmanned airplane so as to be actuated based on self-judgment ability or the wireless control device.SELECTED DRAWING: None |
