Best ppt on Micro air vehicle with flapping wings

  1. 1. MICRO AIR VEHICLES (MAV) WITH FLAPPING WINGS BY -RONAK THAKAREGUIDED BY – Prof. AMRUTA DURAGKAR
  2. 2. What are Micro Air Vehicles? • A Micro Air Vehicle (MAV), or micro aerial vehicle, is a class of unmanned vehicles (UAV). • DARPA(Defense Advanced Research Project Agency) defines- less than 6 inch(15cm) and 4 ounce weight. • Semi-autonomous. • Remote observation of hazardous environments. • Military capability and Fully-functional. • Lift for flight is made with rotary wings and flapping wings. 1
  3. 3. Missions of MAV • Military Surveillance, Reconnaissance,tagging,targetting • Biochemical sensing. • Urban Surveillance,Hostage rescue, Border patrol • Commercial Traffic monitoring Fire & rescue Forestry& wild life survey Real-estate photography 2
  4. 4. Over-the-hill reconnaissance mission Urban operations missions 3
  5. 5. MAV REQUIREMENTS • High image resolution. • Lightweight. • Affordable. • Secret/hidden. • Safe & simple to operate. • Easy to repair. • Rapid electronic connectivity. 4 Based on the missions, an MAV require:
  6. 6. SHAPE OF MAVs • Fixed wing aircraft- Names like“Trocoid”, “Micro STAR”, “Flyswatter”, “MITE”, “Batplane”, “Wasp” • Rotary wing aircraft- “Micro Craft iSTAR”, “Gyrosaucer”,“Helirocket”, and “MICOR” • Flapping wing air craft- “Entomopher” and “Microbat”. 5 The Wasp Micro Craft iSTAR The Microbat
  7. 7. KELVIN’S IDEA • Kelvin’s circulation theorem, the net circulation around the insect body is zero. • Equal & opposite circulation causes lift. • Ordinary insects, this build-up of high lift coefficient is delayed. • One species of insects, Encarsia Formosa, which avoid any delay in built up of maximum lift.
  8. 8. WORKING PRINCIPLE 1] Air comes straight at the wing •Air comes straight at the wings, bends around it and then behind the wing.leaves straight •There is no net action on the air so there can be no lift.
  9. 9. 2] Air passing over the wing •Fig. shows the streamlines, as is the action. •The air passes over the wing and is bent down. •As Newton’s laws suggests, the wing must change something of the air to get lift. •Changes in the air’s momentum will result in forces on the wing. •To generate lift, a wing must divert air down .
  10. 10. MATERIALS USED FOR AIRFRAME CONSTRUCTION • Balsa wood • Foam polystyrene • Foam with a single layer of epoxy fiberglass coating. • Carbon Fiber • Composite (Kevlar or Fiberglass) 9
  11. 11. Components of MAVs 10 • Airframe  Actuators  Sensors • Communication  Transmitter  Receiver  Antenna • Microprocessor • Sensors  Acoustic sensor  Optical sensor
  12. 12. • Electric motors + batteries or fuel cells. • IC engines. • Compressed gas. • Flywheels or capacitors for energy storage.
  13. 13. MAV flight-control system 11
  14. 14. ADVANTAGES • Less size& weight. • Low power requirements. • High reusability. • Speed 10-15 m/sec, not detected by most Radars. • High stability and control. • High lift and slow landing speed. • Can be individually controlled. • Wide range of new missions. 17
  15. 15. DISADVANTAGES • Low image quality due to blurring. • Small range of communication. • Very difficult to design flapping wing mechanism. • Very difficult to control MAVs in bad weather. • Very expensive to design MAVs. • Lithium batteries are expensive, compared to the common alkaline batteries. 18
  16. 16. FUTURE WORK • Use lighter materials, for the frame of MAV,the controllers, the gyroscope for stabilizing. • Developing small power sources. • Designs to achieve high flight speeds better stability in air. • The overall aim will be to minimize the size and weight, to increase the speed, and to maximize the battery life for MAV. 19
  17. 17. CONCLUSIONS • Time of MAVs have arrived. Micro Air Vehicles are the new technology by which a variety of operations are done. • Flapping mechanism have more lift compared to fixed wing mechanism. • Also it can increase the lift without increasing the vehicle speed. • Simple flapping, does not generate sufficient lift. 20
