The drone was developed with the use of unmanned aircraft systems in the\ninitial military sector based on the combination of aerospace technology and\ninformation and communication technologies in a variety of usability, including\nthe civilian sectors. Developed for the field of reconnaissance, it is\nused in both civilian and police sectors as traffic monitoring and high altitude\nreconnaissance missions. It is used in broadcasting and surveillance, while\ncontinuously expanding into the areas of courier delivery and rescue missions.\nBased on the convergence of aviation technology such as various SW,\nsensor and flight control to utilize unmanned system and information communication\ntechnology, commercialization of related technology is being developed\nas a very diverse route. In this paper, we propose and manufacture of\na VTOL UAV. Design process referred to the VTOL development process that\nhas been devised by us, and actual building of a UAV also applied the same\nVTOL development concept. In order to understand the aerodynamic characteristics\nof the aircraft, we have applied the aerodynamic design theory and\nused the CAE method that can replace the actual wind tunnel test. We tested\nthe selection method and criteria for the internal modules that make up the\nUAV, and we were able to assemble the product. FW coding of flight control\ncomputer was conducted for VTOL control. In addition, we developed a LTE\ncommunication module for the long distance flight, and carried out flight\nexperiments with GCS to observe and respond to the flight situation from the\nground. Flight test results showed that stable transition flight was possible\nwith broadband. We could see that the actual performance results were met,\ncompared to our development target values.
