Crash warning device and unmanned aircraft equipped with same

The present invention relates to a crash warning device and an unmanned aircraft equipped with the same. More particularly, when an unmanned aircraft is crashing, the crash warning device warns of crash danger information through a warning sound or in the language of each country, and lights a warning lamp on and off by using a light source so as to show the occurrence of an emergency situation. Accordingly, it is possible to effectively warn of the emergency situation, thereby allowing people to prepare against damage on the ground, and it is also possible to transmit the location of the crashing unmanned aircraft to a user and an emergency call network such as a police station or fire station, thereby enabling quick response to the crash.
