 NANO drones are controlled remotely and are equipped with
camera and microphone.
 The NANO drones are multi functional, military capable,
small flight vehicles.

5. INTRODUCTION
 An unmanned aerial vehicle (UAV), known as a drone, is an
aircraft without a human pilot.
What is DRONE ?
 Drones stand 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.

6.  essentially, a drone is an aircraft without a human pilot
aboard ; a flying robot.
 Small flight vehicles with a different mechanism doing more
missions.
 Suitable for situations where human cannot involve directly.
 Uses more efficient flapping wing mechanism.

13. INTRODUCTION TO FLAPPING WING
MECHANISM
5/14/2015 NANO UNMANNED AERIAL VEHICLE (UAV) 13

14. KELVIN’S IDEA
 KELVIN’S IDEA is from the flapping wing aerodynamics.
 Kelvin’s circulation theorem, the net circulation around insect
body is zero.
 ordinary insects, this build-up of high lift coefficient is
delayed.
 One species of insects, ENCASIA FORMOSA , which avoid
any delay in built up of maximum lift.

15. Working Principle
1. Air comes straight at the wing.
 Air comes straight at the wings, bends around it and leaves
straight behind the wing.
 There is no net action on the air so there can be no lift.

16. 2. Air passing over the wing.
Fig. shows the stream line as in the action.
 To generate lift, a wing must divert air down.
 The air passes over the wing and is bent down.
 As newton’s law suggests, the wing must change something of
air to get lift.
 Changes in the airs momentum will result in forces on the
wing.

29. ADVANTAGES AND DISAVANTAGES OF
NANO DRONE
ADVANTAGES
 Nano drones are much cheaper to maintain than traditional
drones.
 Nano drones can easily recover from in flight collisions.
 Nano drones can save more lives in natural disaster because
their small size and ability to fly makes them very
maneuverable.
 Nano drones can save soldiers in combat positions by
scouting the enemy territory to make sure it is safe to procede.
 Low mass , low power requirements, High lift and low landing
speed.

30. DISADVANTAGES
 Nano drones could be used by enemies to spy on other
nations possibly revealing top secret information for an enemy.
 They are not self powered.
 cannot launch from ground.
 There chances of air bag buckling.

31. CONCLUSION
 MICRO OR NANO air vehicles are new development of the
technology by which a variety of operations are done.
 Simple flapping of the wings does not generate sufficient lift.
 So special mechanism is designed to get the required lift using
weis fogh’s model.
 Flapping mechanism have more lift compared to fixed wing
mechanism.
 It can increase the lift without increasing vehicle speed.
