Also, it comes up with the distinction among VTOL and helicopter and fixed wing aircraft. This paper concentrates on domestic and international drones that utilize VTOL technology. Also, this paper gives the explanation about VTOL’s performance and object. Furthermore, this paper predicts the future of VTOL and which area this technology going to be used.展开更多

To develop the ground control station for unmanned systems, many factors have to be considered from the design stages, such as layout, information component, representation scheme, and human operation methods. Considering such many factors can be very difficult, hence we conducted an in-depth investigation of design factors from major UAV stations around the world. We analyzed the design characteristics and the specifics. In conclusion, we were able to derive some common aspects of design characteristics, which lead to the successful design approach.展开更多

Because it is difficult to expect a wide runway in the city area, the great need is there to develop a vertical takeoff and landing (VTOL) type fixed-wing UAV that does not require any runway. In addition, our goal was to develop a VTOL plane that contains a stable transit flight characteristic. To achieve this goal, we have designed and developed a test plane and the flight parameters have been extensively tested. For the airframe design, the carbon-bar method was selected for vertical takeoff and landing, and the 11-way method was adopted through dynamics analysis. We assembled the airframe and made a prototype using the Pixhawk flight computer. The developed VTOL plane shows a very smooth transition flight. It is expected that the VOTL UAV will be widely used in the city area in the future for various purposes, such as cargo delivery and emergency medical supply delivery.展开更多

However, light aircrafts are somewhat similar in terms of form and structure. In addition, from the flight schools’ point of view, it is not economically beneficial to purchase and maintain light aircraft simulators for each different aircraft type. Globally, there are four types of light aircraft models that are most widely used for basic flight training. If all four models are separately selectable within a single flight simulator, there will be a lot of economic benefits in terms of reducing the purchasing costs as well as the reduction of pilot training costs. In this regard, this study aims at developing the multi-purpose variable-type simulator technology so that it can train four different aircraft types using only a single simulator. The utility of simulator is divided into the use of flight training and the use of leisure time. The flight characteristics are analyzed for each model type to emulate the actual aircraft. It is anticipated that the developed simulator can be produced at a lower cost while occupying less floor space and using less electric energy than the previous one.展开更多
