2.  Small flight vehicles with a different mechanism,
doing more missions.
 Suitable for situations where human cannot involve
directly.
 Uses more efficient flapping wing mechanism.

3.  Reconnaissance applications.
 Operation in constraint environment.
 Bio chemical sensing.

4.  Which uses propellers.
 Which uses flapping wings.

5.  Similar to that of normal aircrafts .
 Using flapping wings.

6.  Lift generation in normal aircrafts.
 In the case of scale reduction.
 Speed.
 Flapping wings.

7.  Lift is generated by the airflow created by the vehicle
speed.
 And also the wing flapping will support the weight of
the vehicle.
 Can be operated at very less vehicle speed.

8.  Fig. (a), (b)- Both the
wings are clapped
together
 Fig.(c) to (e)- The two
wings then starts to fling
open but are still
connected to each other at
the bottom so that these
effectively form a single
body
 Fig.(f), (g)- The wings
break apart and are
completely separated.

9.  Design Procedure
 Estimated Lift

10. • Low mass
• Low power requirements
• High reusability
• High stability and control
• High lift and slow landing speed

11. • They are not self powered
• Cannot launch from ground
• There are chances of air bag buckling

12.  Reconnaissance  Targetting
 Surveillance  Border surveillance
 Defence applications  Traffic monitoring
 Tracking criminals &
 Weather forecast illegal activities
 Wildlife study  Biochemical sensing
&photography  Sesmic detection
 Crowd control

13.  Micro 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.
