3. BEST & FASTEST choice of
Travelling is…..!
Obviously it is Air Travel…
Reasons..
Fastest ,Highly Reliable ,Minimum Cost maximum Distance
travel ,No Physical Barriers and many more.

4. Challenges in air travel..
1. Operation cost is High.
2. Passenger safety .
3. Climate Hurdles.
4.Airport maintenance .
5. Fuel cost .
6.Passengers to Flight
ratio.
And many more….

5. Solution for the
PROBLEMS…..??
Here we suggest one…..!!!

6. Lets go
through some
Basics in
working of an

15. AIRCRAFT controls..

16. Now we’ll present
few points on the
new suggested
concept of...
BLENDEDWING

33. ADVANTAGES :-
• Increase in the passenger capacity up to 800
• Reduction in fuel consumption of the aircraft(burns 27% lesser fuel)
• High L/D ratio due to a decreased relative wetted area(area which is in
contact with the external airflow)
• Favourable load distribution along the span
• Possible engine noise shielding
• 15% lower take-off weight
• 12% lower empty operating weight
• 27% lower total thrust
• 27% lower fuel BURNED
• 20% higher L/D ratio as compared to conventional aircraft
• Lower production cost (lower production costs come from not have as
many tight bends so the manufacturing costs go down)
• Lower fares
• Reduced airport/airspace congestion
• Improved safety

34. DISADVANTAGES :-
• High bending stresses resulting from the effect of pressure on
the box-like shape of the BWB
• High bending stress associated with a non-cylindrical pressure
vessel.
• Typical aircrafts have a cylindrical shape which requires less
strength and is easier to pressurize as opposed to the interior
shape of a BWB

35. FUTURE SCOPES…
With the increase in population exponentially we cannot have a
congested traffic in the mid air or an “Air Traffic Jam”. So we
need some new innovation which can carry more passengers,
have a small size and less pollutant and can integrate new thrust
mechanisms like hybrid engines and produce less noise and take
less runaway for take off and landing and terminal congestion
With these factors in consideration we can assume that by 2020
the world might see the BWB in their airport with its eye
catching design and body like an UFO.

36. CHALLENGES Ahead ..
• Structural and material (structural – wingspan exceeds 262ft.
Or 80m)& (Structures is back to the pressurization issues and
the integration issue revolves around making the structure
clean enough to work aerodynamically and achieve the
savings potential.)
• Aero structural integration ,Aerodynamics ,Controls
• System integration ,Infrastructure

37. APPLICATIONS :-
• Long distance travel flights with high capacity of fuel and
people.
• Cargo flights with more space.
• Stealth UAV’s for defense operations.
• High altitude flights for long haul .
• Short runway required for landing resulting in air connections
to remote and small airports in large capacity.

38. CONCLUSIONS :-
• The BWB is fuel efficient
• Less material required to produce the body
• Less complicated design
• Less noise and polluting
• High L/D ratio
• Carry more passengers
• Less size compared to conventional aircraft
• Aerodynamic design
• Can integrate new hybrid turbines AND turboprop fans
• From the conceptual point of view, the BWB design has been
demonstrated to be more attractive than the conventional aircraft.
• The flight features of small drag value and less engine thrust
requirement predict to perform with less noise emission, and make
it a more environmentally-friendly vehicle.
