SYSTEMS IN THE UNMANNED AERIAL VEHICLES (U.A.V.'s

International Journal of Research, 2022

Unmanned Aerial Vehicles or Remotely Piloted Aircrafts are used in most aviation applications and military applications. UAVs are consisting of different systems. Civilian UAVs systems made up of the unmanned aircraft system, human element, payload, control elements, and data link communication architecture. But UAV used for military applications are also includes the weapon systems, surveillance systems. Unmanned Aerial Vehicle systems also includes many subsystems. Unmanned Aircraft System includes the fixed wing and vertical takeoff and landing (VTOL). Command and control element system consists of two subsystems viz. Autopilot and Ground control station. Communication data link system includes Line-of-sight (L-O-S) and Beyond Line-of-sight (B-L-O-S) subsystems. In payload system there are Electro-Optical, Thermal infrared, Spectral, Laser subsystems. Nowadays, there are many ways to perform the Launch and recovery mission for modern UAVs. Such as Catapult system. But in most of the UAVs launch and recovery element is only for suitable takeoff and landing. The most important element in UAV system is human element which consist of a pilot or sensor or supporting ground crew. For all operations of UAVs command of pilot of UAV is responsible. For carrying the safe operations or mission’s human element is necessary in UAV system. But in modern UAVs automation takes place of human elements. And in automation UAV performs the command based on artificial intelligence which is programmed in UAV.

Autonomous UAV (Unmanned Aerial Vehicle) For Navigation and Surveillance Purposes

Global Journal of Research In Engineering, 2012

The use of autonomous vehicles, for a wide variety of applications, has been increasing during the latest years. Land-based vehicles can be used for many purposes, but are not as versatile as could be desired, because they are dependent on the terrain. Aerial vehicles, such as aero planes and helicopters, do not depend on the terrain in the area of operation, as the land based vehicle. An autonomous helicopter has an advantage in maneuverability compared to an autonomous aero plane, which is not able to hover (stand still in the air). This and the ability to take off and land in limited spaces are clear advantages of the autonomous helicopter. An autonomous helicopter is a versatile platform for a wide variety of applications. It can be used in situations as agricultural crop dusting, search and rescue missions, inspection of bridges or power lines, surveillance of larger areas etc. Helicopters are complex, high performance machines designed to ensure the safety of their occupants d...

Unmanned aerial vehicles (UAV)Drone

Sanowar, 2023

UAV is defined as an aerial vehicle that does not carry a human operator, uses aerodynamic forces to provide vehicle lift, can fly autonomously or be piloted remotely, can be expandable or recoverable, and can carry a lethal or nonlethal payload. It is controlled either autonomously by on-board computers or by remote control of a pilot on the ground. Its usage is currently limited by difficulties such as satellite communication and cost. A Drone has been built that can be operated by radio frequency controller and send live audio-visual feedback. The developed Drone control system has been simulated in MATLAB/Simulink. The simulation shows a very stable operation and control of the developed Drone. Microcontroller based drone control system has also been developed where a RF transmitter and receiver operating in the frequency of 2.4 GHz are used for remote operation for the Drone. Earlier, Drones were deployed for military applications such as spying on both domestic and international threats. The developed drone in this work can be used for a number of applications, such as policing, firefighting, monitoring flood effected areas, recording video footage from impassable areas and both military and non-military security work. In addition, using an Android mobile device incorporation with GPS has been used for live position tracking of Drone and real time audio-visual feedback from Drone.

Aspects regarding the concept, development and use of modern uavs

UAVs, constitutes an important branch of aerospace, UAVs sites because construction and operating costs incomparably smaller than the well-known aircraft will be used increasingly over the coming decades. . The armed interference must be done based on some highly accurate information that must be gathered without endangering the human lives. The armed interference must be done based on some highly accurate information that must be gathered without endangering the human lives. This is the role the unmanned air vehicles (UAVs) presently play; they can perform both the function of surveillance, information gathering, data storage and their transmission to the ground stations, and the function of interference, when needed.

Review of Unmanned Aircraft System (UAS

Unmanned Aircraft Systems (UAS) is an emerging technology with a tremendous potential to revolutionize warfare and to enable new civilian applications. It is integral part of future urban civil and military applications. It technologically matures enough to be integrated into civil society. The importance of UAS in scientific applications has been thoroughly demonstrated in recent years (DoD, 2010). Whatever missions are chosen for the UAS, their number and use will significantly increase in the future. UAS today play an increasing role in many public missions such as border surveillance, wildlife surveys, military training, weather monitoring, and local law enforcement. Challenges such as the lack of an on-board pilot to see and avoid other aircraft and the wide variation in unmanned aircraft missions and capabilities must be addressed in order to fully integrate UAS operations in the NAS in the Next Gen time frame.

Unmanned Aerial Vehicle For Surveillance

2014

UAV (Unmanned Aerial Vehicle) is an air vehicle which is largely used for surveillance, monitoring, reconnaissance, data relay, and data collection or to enter the area which is not safe for human i.e. flood affected or virus affected area. Present paper discusses the systematic design, data analysis, different property calculations and then manufacturing of delta wing type of UAV with low cost which successfully flew in the sky in Mumbai. It measures the altitude, captures the real image as well as videos that used for the surveillance purpose. ———————————————————— Introduction: Birds can fly in sky due to their inherent characteristics. They are the dominant in the sky. It is human characteristics to dominate or rule over other. So they tried their best to fly in sky from dawn of civilization. And they got it through the success of Wright brother’s in 1903. Subsequently many modernization and invention had done through 19th century and now a day’s fly without pilot is one of the ...

Introduction to UAV Systems

UAV Networks and Communications

This chapter provides the background and context for unmanned aerial vehicles (UAVs) and UAV networks with a focus on their civilian applications. It discusses, for example, the types of UAVs, fuel, payload capacity, speed, and endurance. It will also discuss the state-of-the-art in engineering and technology aspects of UAVs and UAV networks and the advantages of UAV networks, including enhanced situational awareness and reduced latency in communications among the UAVs. It presents the applications of UAV networks, research opportunities, and challenges involved in designing, developing, and deploying UAV networks, and the roadmap for research in UAV networks. Over recent decades, many different terms have been used to refer to UAVs, the most recent of which being remotely piloted aerial system (RPAS), which insists that the system is somehow always operated by somebody on the ground who is responsible for it. The term is very much like the old name for UAVs of the 1980s, that is remotely piloted vehicle (RPV). The RPAS puts emphasis on the fact that the aerial system includes not only the flying vehicle but also, for example, a ground control station, data link, and antenna. It also provides room for the case where several aircraft belonging to the same system may be remotely operated as a whole by a single human operator. In that case, it is not possible for the operator to actually control each flying vehicle as if he or she was an RC pilot. Yet, in aeronautics, piloting an aircraft basically means flying an aircraft. It has a very precise meaning which is related to the capability to control the attitude of the vehicle with respect to its center of gravity. While most UAVs are remotely operated, they almost all have an on-board autopilot in charge of flying the aircraft. Therefore, it is not a remotely piloted vehicle but only a remotely operated vehicle where navigation commands are sent to the aircraft. Furthermore, navigation orders such as waypoints, routes, and decision algorithms may even be included in the on-board computer in order to complete the mission without human action along the way. In this way, human judgment is devoted to actions at higher levels, such as decision making or strategy definition. The term "remotely operated aircraft system" (ROAS) would therefore make more sense to the current scientific community. Nevertheless, in the present book, the classical terms UAV or UAS have been chosen to refer either to the aerial vehicle itself (UAV), or to the whole system (UAS), which classically includes a set of UAVs (or possibly one), a control station, data links, a support equipment, and human operators. 1.1.2 Flapping-wing UAVs From the very beginning of aviation, some authors have argued that engineers should get inspiration from existing flying animals, either birds or insects. The idea underlying such a view being that animals have been gradually optimized over the centuries.
