INTRODUCTION An unmanned aerial vehicle (UAV), commonly known as a drone is an aircraft without a human pilot on board. Its flight is either controlled autonomously by computers in the vehicle, or under the remote control of a pilot on the ground or in another vehicle. There are a wide variety of drone shapes, sizes, configurations, and characteristics. Historically, UAVs were simple remotely piloted aircraft , but autonomous control is increasingly being employed. PAGE NO 2Dept. of ECE,KLECET </li><li> 4. HISTORY August 22, 1849, when the Austrians attacked the Italian city of Venice with unmanned balloons loaded with explosives. The balloons were launched from the Austrian ship Vulcano. THE AUSTRIAN BALL0ONS PAGE NO 3Dept. of ECE,KLECET </li><li> 5. The first pilotless aircraft were built during and shortly after World War I. Leading the way, using A. M. Low's radio control techniques, was the "Aerial Target" of 1916 Hewitt-Sperry Automatic Airplane, otherwise known as the "flying bomb" made its first flight, demonstrating the concept of an unmanned aircraft. World War II : Reginald Denny and the Radioplane World War I : worlds first uav 1916 The first large-scale production, purpose-built drone was the product of Reginald Denny. Demonstrated a prototype target drone, the RP-1, to the US Army. Denny then bought a design from Walter Righter in 1938 and began marketing it as the "Dennymite", and demonstrated it to the Army as the RP-2, and after modifications as the RP-3 and RP-4 in 1939. They manufactured nearly fifteen thousand drones for the army during World War II. PAGE NO 4 Dept. of ECE,KLECET </li><li> 6. CLASSIFICATION OF UAVS PAGE NO 5Dept. of ECE,KLECET </li><li> 7.

Uav system elements PAGE NO 1 1Dept. of ECE,KLECET </li><li> 13. An Unmanned Aircraft or Aerial System can be divided into three distinct elements: 1.THE VEHICLE OR PLATFORM 1.1 THE AIRFRAME PAGE NO 12 The airframe of an aircraft is its mechanical structure. It is typically considered to include fuselage, wings and undercarriage and exclude the propulsion. Airframe design is a field of aerospace engineering that combines aerodynamics, materials technology and manufacturing methods to achieve balances of performance, reliability and cost.

Mechanically, a gyroscope is a spinning wheel or disk in which the axle is free to assume any orientation An Accelerometer is a device that measures acceleration. Accelerometers are sensors that can measure the acceleration of the body in a specific direction PAGE NO 14Dept. of ECE,KLECET </li><li> 16. 2 .The Payload 2.1 ELECTRO-OPTICAL SENSING SYSTEMS AND INFRARED SYSTEMS PAGE NO 15 To provide ground forces critical, time-sensitive information about the people hiding around the corner or entering a town by vehicle. Strapped to manned aircraft or aerial drones, these multispectral sensors operate in multiple modes usually with both day (electro-optical camera) and night (infrared camera) capability. Dept. of ECE,KLECET </li><li> 17. 2.1 Synthetic aperture radar PAGE NO 16Dept. of ECE,KLECET </li><li> 18. 2.2 Munitions Fielding larger Unmanned Aerial Systems (UAS) ,such as MQ-9 reaper, capable of carrying much heavier payloads such as laser guided gravity dropped bombs and SDB bombs. The main benefit of such weapons is their relative low cost, ability to deploy from high altitude and absence of visual launch signature.

CASE STUDY OF PREDATOR C: AVENGER PAGE NO 19 Its first flight occurred on 4 April 2011. Unlike the previous MQ-1 Predator and MQ-9 Reaper (Predator B) drones. The Avenger is powered by a turbofan engine, and its design includes stealth Features such as internal weapons storage, and an S-shaped exhaust for reduced heat and radar signature.

Advantages of uav Doesnt require a qualified pilot. Can enter any environments. Reduces exposure risk of the aircraft operator. Can stay in the air for up to 30 hours. Can be programmed to complete the mission autonomously. PAGE NO 21Dept. of ECE,KLECET </li><li> 23. DIS-Advantages of uav Costly compared to manned vehicles. Limited Abilities. More hardware complexity. PAGE NO 22Dept. of ECE,KLECET </li><li> 24. Applications of uav Remote Sensing Aerial Surveillance Transport Search&amp;Rescue Armed Attacks PAGE NO 23 </li><li> 25. CONCLUSION With more research and technological advances, it is possible that the UAV may well replace manned combat aircraft in the future. The advantages of UAV against manned aircraft are numerous. First is the risk of being shot down. PAGE NO 24Dept. of ECE,KLECET </li><li> 26.
