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 this ppt click on this link https://adf.ly/PdL4V

1. DRONE:
UNMANNED AERIAL VEHICLE

2. 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

3. 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.

5. 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

6.  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

• Endurance-14hours

14. 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,

EXPLORATION & PRODUCTION:
IN TRANSPORT
IN SCIENTIFIC RESEARCH
IN ARMED ATTACKS:
IN SEARCH & RESCUE:

17. 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

18. 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.

19. 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.
