Presentation Description

An unmanned aerial vehicle (UAV), commonly known as a Drone, is an aircraft without a human pilot on board. UAVs can be remote controlled aircraft (e.g. flown by a pilot at a ground control station) or can fly autonomously based on pre-programmed flight plans or more complex dynamic automation systems A UAV is defined as being capable of controlled, sustained level flight and powered by a jet or reciprocating engine. In addition, a cruise missile can be considered to be a UAV, but is treated separately on the basis that the vehicle is the weapon. Unmanned Aerial Vehicles (UAVs) are aircrafts that fly without any humans being onboard. They are either remotely piloted, or piloted by an onboard computer. This kind of aircrafts can be used in different military missions such as surveillance, reconnaissance, battle damage assessment, communications relay, minesweeping, hazardous substances detection and radar jamming. However they can be used in other than military missions like detection of hazardous objects on train rails and investigation of infected areas. Aircrafts that are able of hovering and vertical flying can also be used for indoor missions like counter terrorist operations To download detailed ppt click on this link https://adf.ly/PdL4V

DRONE: UNMANNED AERIAL VEHICLE:

DRONE: UNMANNED AERIAL VEHICLE Seminar Co-Ordinator: Mr. Mani Prakash Seminar Guide: Ms. Jhelam Pandey Seminar Presented by: Shivesh Kumar Srivastav Amit Singh Dhirendra Kumar Yadav

Introduction:

Introduction An unmanned aerial vehicle ( UAV ), known as a drone , is an aircraft without a human pilot. Drone stands for Dynamic Remotely Operated Navigation Equipment Its flight is either controlled autonomously by computers or under the remote control of a pilot on the ground

Birth of UAV’s:

Birth of UAV’s The earliest attempt at a powered unmanned aerial vehicle was A. M. Low's "Aerial Target" of 1916 After World War-I, including the first scale RPV, developed by the film star and model airplane enthusiast Reginald Denny in 1935 The birth of U.S. UAVs began in 1959 when United States Air Force officers, concerned about losing pilots over hostile territory. The August 2 &4, 1964,U.S. Navy initiated America's highly classified UAVs into their first combat missions of the Vietnam War.

UAV is a “System”:

UAV is a “System” Unmanned Aircraft Transportable Ground control System Cockpit

Sub-System of UAVs:

Sub-System of UAVs COMMUNICATIONS:- Operates on ultra high frequency Communicates with ku-band system Operates with uplink frequencies from 15.15 to 15.35 GHz and downlink frequency 14.40 GHz to 14.83 GHz NAVIGATION:- Avionics use satellite based system such as GPS and WAAS It calculates position automatically

PowerPoint Presentation:

MONITORING:- Includes GPS system High resolution video camera Super high resolution still camera COLLISION AVOIDANCE SYSTEM:- Use traffic and collision system Smaller aircraft use simple traffic alerting system Aircraft use ground proximity warning system WEATHER SYSTEM:- Use weather radar and lighting detector system

DRDO Rustom:

DRDO Rustom Rustom is a Medium Altitude Long Endurance unmanned combat air vehicle being developed by DRDO. Digital Flight Control and Navigation System, Automatic Take off and Landing. Aerodynamic configurations, High aspect ratio wing, Composite airframe integrated with propulsion system, De-icing system for wings

DRDO Nishant:

DRDO Nishant The DRDO Nishant is an developed by India's ADE . Day/night capability training vehicle. Its range of Service ceiling : 3,600 m (upto 11,800 ft)

LAKSHYA PTA:

LAKSHYA PTA Lakshya is an Indian remotely piloted high speed target drone system developed by ADE of DRDO. Service ceiling: 9,000 m (29,528 ft) 5,000 metres (16,404 ft) with towed target. Launch: Rocket Assisted

Comparison with US DRONE:

Comparison with US DRONE US Drone-Global Hawk: Length-13.5m Wingspam-35.4m Height-4.6m Empty-Weight-3850kg Max loaded weight-10400kg Maximum speed-650kmph Service ceiling-20000m Endurance-34hours Indian Drone-Rustom-H : Length-9.5m Wingspam-20.6m Height-6.1m Empty weight-1800kg Max loaded weight-2150kg Maximum Speed-225kmph Service ceiling-10668m Endurance-14hours

UAV vs. Manned Aircraft:

UAV vs. Manned Aircraft Remotely piloted vehicles will never fully replace manned aircraft They can perform an increasingly sophisticated array of missions due to their small size and decreased radar. To wholly replace man would be expensive and technically risky. UAS should be only considered for certain types of missions for which it can be a cost effective With a continuing trend of miniaturization in electronics, the UAV can be made much smaller and cheaper Size largely determined by the size of the payload,

Uses Of UAV:

Uses Of UAV IN COUNTER TERRORISM ACTIVITY: IN COMMERCIAL AERIAL SURVEILLANCE:

PowerPoint Presentation:

IN OIL, GAS AND MINERAL EXPLORATION & PRODUCTION: IN TRANSPORT IN SCIENTIFIC RESEARCH IN ARMED ATTACKS: IN SEARCH & RESCUE:

ADVANTAGES:

ADVANTAGES Does not contain, or need, a qualified pilot on board Can enter environments that are dangerous to human life Reduces the exposure risk of the aircraft operator Performing visual or thermal imaging of a region Measuring cell phone, radio, or, TV coverage over any terrain Can be programmed to complete the mission autonomously even when contact with its GCS is lost

DISADVANTAGES:

DISADVANTAGES Immoral Civilian casualties Angers many people in foreign countries(infringe upon sovereignty) Can be hacked or given viruses Too small for transportation of materials Low resistance to weather Cannot refuel in flight If contact is lost with the ground station, the vehicle may be lost.

CONCLUSION:

CONCLUSION Unmanned Aerial Vehicles are an exciting field in the world of aviation, with new discoveries. Over the next 16 years, UAVs will become a significant component of military, civil, and perhaps even commercial aviation. However, the very dynamic nature of the field also creates a significant amount of uncertainty. The wide range of UAV physical and performance characteristics, many of which will be very unlike any current aircraft, will place additional challenges on an air traffic management system.
