Accurate Position

In the environment of harsh weather or obstacles, the corresponding monitoring department can't achieve remote control and acquire the accurate location of the unmanned aerial vehicle (UAV). According to the existing problem this paper designs a logical control module based on single chip microcomputer (SCM) C8051F040 and UAV real-time tracking system which is positioned by GPS. In this design, through the analysis and extraction of the GPS data, then transmit these data to the host computer through the USB interface with high speed, the unmanned aerial vehicle (UAV) flight vector position such as longitude and altitude information will be displayed by the host computer. After tested for several times, this vector pursuit system can acquire the accurate position of the unmanned aerial vehicle (UAV) and the corresponding flight path within 20 km. To some extent, it provides an effective guarantee for the remote control and monitoring department.

Nuclear, Biological and chemical disasters are tragic and should never happen. Unavoidably occurred, access and reach are difficult because rescue personnel are exposed to hazards. Drone is an unmanned aerial vehicle that can be operated by remote control or autonomous aviation. It has some advantages in NBC disaster as followings:First, drone can take a picture and record the scene in contaminated zone. Communication with injured is also possible without exposure to rescue team. Triage can be performed by analysis of movement, breathing and responsiveness, etc.Second, atropine and oxime are essential to nerve agent poisoning. It can be delivered by drone only inside contaminated zone for survivors.Third, drone can collect specimen without human exposure. Investigator can analyze the extent of pollution in remote laboratory with this specimen.Fourth, survivor can be evacuated from disaster area by drone itself. This operation needs heavy capability that would lift patients.I hope that NBC disaster could be overcome with this useful modern convenience.

The Cost

Tilt-rotor unmanned aerial vehicles have attracted increasing attention due to their ability to perform vertical take-off and landing and their high-speed cruising abilities, thereby presenting broad application prospects. Considering portability and applications in tasks characterized by constrained or small scope areas, this article presents a compact tricopter configuration tilt-rotor unmanned aerial vehicle with full modes of flight from the rotor mode to the fixed-wing mode and vice versa. The unique multiple modes make the tilt-rotor unmanned aerial vehicle a multi-input multi-output, non-affine, multi-channel cross coupling, and nonlinear system. Considering these characteristics, a control allocation method is designed to make the controller adaptive to the full modes of flight. To reduce the cost, the accurate dynamic model of the tilt-rotor unmanned aerial vehicle is not obtained, so a full-mode flight strategy is designed in view of this situation. An autonomous flight test was conducted, and the results indicate the satisfactory performance of the control allocation method and flight strategy.

Abstract: UAV or unmanned aerial vehicle is an air vehicle or what we often call an airplane that is controlled without a crew but controlled by a pilot remotely using a remote control. This study uses quantitative experiment methods because in this study it must be carried out when the UAV is flying using the autonomous waypoint method. Running the UAV with the autonomous waypoint method, we can use the Mission Planner software. First, we have to install the application on the mission planner and install pixhawk on the UAV which will act as the UAV brain that will receive and execute flight commands that will be sent by the mission planner later. The mission planner can also directly display flight data such as UAV altitude, UAV speed, UAV location, then the mission planner can also store flight data run by the UAV. The Autonomous waypoint method has been widely used in the military field, such as to carry out attacks on the enemy, reconnaissance, and patrol in an area quickly, and can also reduce casualties during combat operations.

Background Oriented Schlieren

To optically capture and analyze the structure and changes of the flow field of a weak airflow object with high accuracy, this study proposes novel weak flow field extraction methods based on background-oriented schlieren. First, a fine background pattern texture and a sensor network layout were designed to satisfy the requirement of weak flow field extraction. Second, the image displacement was extracted by calculating the correlation matrix in the frequency domain for a particle image velocimetry algorithm, and further calculations were performed for the density field using Poisson’s equation. Finally, the time series baseline stacking method was proposed to obtain the flow field changes of weak airflow structures. A combustion experiment was conducted to validate the feasibility and accuracy of the proposed method. The results of a quad-rotor unmanned aerial vehicle experiment showed that the clear, uneven, and continuous quantitative laminar flow field could be obtained directly, which overcame the interference of the weak airflow, large field of view, and asymmetrical steady flow.
