“…Quadcopter is the most used UAV in many activities which they have four propellers that provide to the quadcopter. Basically, UAV is a flying vehicle that can be remotely or programmed to conduct autonomous task [1] which do not need a pilot to control instead all people who learned to fly the UAV start at young age. Previously, the usage of UAV only limited for military purpose but nowadays, the function becomes variety that can be used for other activities such as photography, regional mapping and entertainment media [2].…”

In this study, the main focus is to study of air flow characteristic of UAV quadcopter propeller at incorporate blade profile using variableangle of attack (AoA)and revolution per minute (RPM) with its twisted blade using Computational Fluid Dynamics (CFD) / Ansys tool. Three propellers have been designed which Propeller 1 is untwisted while Propeller 2 and 3 twisted at certain angle. Three speeds which are 4000 rpm, 6000 rpm and 8000 rpm have been set for each propeller are being analysed using ANSYS Fluid Flow (fluent). The result shows the different thrust force generated by three propellers and Propeller 2 (33.6757 N) has the highest thrust force generated compared to Propeller 1 and 3 especially at 8000 rpm. This is due to the suitable twisting angle profile that has been set at the Propeller 2at this operating speed. For comparison, Propeller 3 produce the highest thrust force of 18.44Nat 6000 rpmexceeding Propeller 2 which is 17.81 N.To summarize, each propeller blade profile has a distinctive aerodynamic performance and should be adopted by matching the flight operating condition. Higher rpmgenerateshigherthrust force, and increaselift and drag coefficient.

“…Drones are the most popular ones as they are tools that can carry out multiple applications which simplify human work. For example, they can be used in journalism to capture different perspectives [1], in crop spraying [2], for goods transport and shipment [3], in search and rescue, in agriculture, among others.…”

This paper aims to describe the design and implementation of the height control system for the quadrotor AR. Drone 2.0 making use of a fuzzy logic in a previously established environment. This device has a height control system both in simulation and in the real platform. Three controllers are developed by fuzzy logic whose parameters are obtained from the drone's sensors in such a way that it allows to control height and angles of orientation (Pitch, Roll and Yaw) as long as certain levels of battery charge are considered so that the system does not become unstable. For the visualization and interaction with the drone a Matlab® interface is designed and implemented, that allows communication between the user and all system functions in such a way that the mode of execution can be chosen, follow the reference parameters autonomously, store data for a later analysis, and visualize the displacements to observe the efficiency of system.

This entry considers the ambiguous notion of drone journalism by reviewing its various meanings and considering how drones are articulated in news media discourse and employed by newsrooms. Drones have seen increasing use by journalists as newsgathering tools. However, the emergence of drone journalism has not been accompanied by a solid set of procedures and conventions, nor is it a widely accepted subject in journalism education. Although the intersection of journalism and drones lies more on the periphery of journalism studies, theoretical and empirical explorations of drone journalism reveal regulatory and ethical complexities, the implications of drone imagery for journalism as a cultural practice, and the porous boundaries between witnessing and surveillance in negotiations on the social roles of drone journalists.
