  1. What is UAV? UAVs are capable of operating without an internal pilot; are tethered by a radio control link; and can be preprogrammed for both flight and payload operations prior to launch. a UAV is 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.
  3. 1923First radio controlled flight. 1944First use of a cruise missile in combat(Fieseler Fi 103) 1946First UAV used in the science research role(Northr op QP-61) 1959First UAV used in the reconnaissance role 1998 First trans-Atlantic crossing by an unmanned aircraft (Insitu Aerosonde) -2001First trans-Pacific crossing by an unmanned aircraft (Global Hawk)
  4. DE PALMA: He has developed The Kettering Aerial Torpedo, later called the “Kettering Bug,” was a small biplane with 4- cylinder engine and guided by gyroscopes, a barometer, and a mechanical “computer.”
  5. British-born actor Reginald Denny, who had served in the Royal Flying Corps during World War I, developed a fascination with radio-controlled aircraft in the 1930s. He and his partners formed the Radio plane Company and created the “Radio plane OQ-2,” the first mass-produced UAV, at their southern California-based facility.
  6. Fu-Go Balloons  The first truly intercontinental weapon system, Japan's “Fu- Go” balloons were designed to cause widespread forest fires and damage to America during World War II.  The hydrogen-filled balloons measured 30 feet in diameter.  Each carried a payload of 32 paper sandbags, two incendiary devices, one small bomb, and an altitude regulation mechanism.
  7. The best-known unmanned vehicle of World War II was the German Fiesole Fi 103. It also called the V-1 “Buzz Bomb” (“V-1” stood for Vergeltungs waffe Eins, or “vengeance weapon one”). The V-1 was powered by a pulsejet engine that made a distinctive buzz.  It carried a 2,000-pound warhead approximately 150 miles, and had a sophisticated guidance system consisting of gyroscopes, barometers, and an anemometer, which was used to calculate distance flown.  The Germans launched roughly 20,000 V-1s at Allied targets, primarily in London and Antwerp, Belgium.
  8. A second-generation turbojet-powered Fire bee, built by Ryan Aeronautical Company and developed from a target drone initially developed for the U.S. Air Force, led to the AQM-34, which ushered in modern unmanned reconnaissance aircraft. From the mid- 1960s to the mid-1970s, the AQM-34 flew tens of thousands of missions over North Vietnam, parts of China, and even the Soviet Union, obviating the risk posed by manned reconnaissance flights.
  9. The RQ-1 Predator, probably the best-known modern UAV, made its first test flight in 1994. Produced by General Atomics Aeronautical Systems—based on a design by Abraham Karem, a former engineering officer for the Israeli Air Force—it was designed for “long loiter” reconnaissance work. The RQ-1 has evolved, and today its variants patrol the U.S.-Mexico border, collect air samples for scientific research, and unleash Hellfire air-to-ground missiles on military targets.
  10. Soaring even higher than the Predator—which the military considers a medium altitude UAV— the Northrop Grumman RQ-4 Global Hawk is a high-altitude, long endurance aircraft with performance and sensor capabilities so impressive it’s scary. Born out of a 1995 DARPA (Defense Advanced Research Projects Agency) request, the Global Hawk can fly more than 32 hours at a stretch and loiter at altitudes as high as 65,000 feet, with a suite of sensors that can see through clouds, dense fog, haze, and dust storms.
  11. In 2007, an Aerosonde UAV took off from the NASA Wallops Flight Facility in Virginia and headed into Hurricane Noel, a Category 1 storm churning up the eastern coast of the United States.  During its 17 hour, 27 minute flight into Noel, the Aerosonde flew as low as 300 feet above sea level, far lower than a piloted airplane would dare travel inside a hurricane eye wall. Other non-military UAV uses include crop monitoring, search and rescue, fire spotting, mineral exploration, aerial photography and ground mapping.
  12. TYPES OF UAV’S Target and decoy - providing ground and aerial gunnery a target that simulates an enemy aircraft or missile Reconnaissance - providing battlefield intelligence Combat - providing attack capability for high-risk missions . Research and development - used to further develop UAV technologies to be integrated into field deployed UAV aircraft Civil and Commercial UAVs - UAVs specifically designed for civil and commercial applications.
  13. A UAV is not just the vehicle that flies. An unmanned Aircraft or Aerial system/vehicle can be divided into three brief element  The vehicle or platform  The Payload  The Ground control station
  14. The vehicle is the Actual air frame and the means to load the payload to its optimal position. The propulsion system has to be tailored according to the mission. The Flight control system ensures the UAV Follows the pre-programmed or Ground Control station. The Airframe The propulsion system The flight control computer or system The precision navigation system
  15. The purpose of a UAV is deliver or collect data usually in a dull , dirty or dangerous environment. The payload is the most important element of the whole UAV as this determines the payback. The vehicle itself does not deliver the message or the data : it merely gets the payload to the best location. Electro-optical sensing system and scanners Infra-red system Radars Munitions
  16. A GROUND CONTROL STATION is a land or sea based control centre that provides the facilities of controlling the unmanned vehicles or rockets in the air or in space. And for this, the CGS must have secure communication system and air traffic management infrastructure. An avionics flight Data processing. Navigation system System Health monitoring. Graphical images and position mapping. Secure communications system.
  17. Firefighting Police Disturbances (crime scenes, etc) Reconnaissance Support in natural disasters i.e., hurricanes, mudslides Surveillance (in war zones) UAS systems often preferred for missions that are too ´dull, dirty or dangerousμ for manned aircraft

  24. HOW UAV IS BETTER THAN OTHER METHOD? They can perform an increasingly sophisticated array of missions due to their small size and decreased radar, acoustical, and infrared signatures. They can perform an increasingly sophisticated array of missions due to their small size and decreased radar, acoustical, and infrared Maximum flight hours 30+ signatures. 3000lb fuel capacity Maximum flight hours 30+ Fly above 52,000ft 3000lb fuel capacity Operate at night Fly above 52,000ft  Above Smoke Operate at night With a continuing trend of miniaturization in electronics another components, the RPV can be made much smaller and cheaper With a continuing trend of miniaturization in electronics another components, the RPV can be made much smaller and cheaper
  25. Does not contain ,or need a pilot on board. Can enter environments that are dangerous to human life. Reduces the exposure risk of the aircraft operator. Can stay in the air for performing a precise, repetitive raster can of a region, day-after-day, night-after-night in completed darkness or in fog, under computer control: performing a geological survey, performing visual or thermal imaging of any region. Can be programmed to complete the mission autonomously even when contact with its GCS is lost. Inexpensive to manned aircrafts.
  26. Need for large band width communications.. Vulnerability to jamming. Low survivability in military operation.
  27. CONCLUSSION UAV Systems are newcomers in the Air Traffic Developments made for UAV Systems (automatic modes ,enhanced situation awareness,...) might reciprocally be beneficial to other civil aviation applications.
