What is aviation?

• Aviation is the practical aspect or art of aeronautics, being the design,

development, production, operation, and use of aircraft,

especially heavier-than-air aircraft.

DEVELOPMENT OF AVIATION

EARLY FLYING MACHINES

First Modern Aircraft

1) Invented by Sir George Cailey.(Father of aeroplane)2) Model Glider with layout of modern aircraft3) Concept of modern aircraft as fixed wing flying machine4) Concept of thrust, lift, drag and weight5) Design of full size manned glider or governable parachute.

The Wright Flyer: The first sustained flight with a powered, controlled aircraft. ( Invented by the Wright brothers in 1903)

THE WRIGHT BROTHERS

Wright brothers technology

• Wood and cloth • Wing warping for control (three

axis control)• Engine made in their bicycle

shop• Spruce frame –but wood is a

composite containing cellulose fibres in a lignin and hemi cellulose matrix

• Muslin for surfaces- textile structure of cotton fibres

AIRCRAFT OPERATIONCockpit: The area usually in front of the aircraft from which it is controlled and operatedFLIGHT INSTRUMENTS :Attitude Indicator

Airspeed Indicator

Magnetic Compass

Heading Indicator

Altimeter

AIRPORTLocation for take off and landing of an aircraft

Take Off:The phase of flight in which an aerospace vehicle goes from ground to flying in the air

LandingPart of flight where a flying aircraft returns to the ground

Aviation at present

• At present times aviation has been modified and developed to a great extent.

• Speed,luxury,safety have been increased• Use of drones in military and civilian aspect• Improved radar system

Aviation in Bangladesh

At present Bangladesh have 3 international airports in Dhaka, Chittagong and Sylhet. Other than that there are eight

domestic airports.The airlines in Bangladesh are Bangladesh Biman Airlines,

United Airways, Regent Airways, NovoAir.In Bangladesh Air force is currently using combat aircrafts

like MiG-29, F-7, Shenyang FT-6. Lockheed C-130

Fields of improvement in modern aircrafts

1)Reduced structural load.2)Reduced stability requirements.3)New Airfoil designs.4)Flow control.5)Use of composite materials.6)Propulsion7)New configuration concepts

AIR CRAFTDESIGNS

OF THE FUTURE

Helios cthomas

Icon II

Green Supersonic Machine

SUGAR

Joined Wing Concept

Oblique Flying Wing

Blended Wing Body Lift to drag ratio 50% greater that conventional airplane.

Wide airfoil shaped body.

Efficient high lift wings.

Increased fuel efficiency.

Lower noise.

Some technologiesOf future aviation

Bionic Structures

Self reliant Materials

CompositeMaterials Biopolymer membrane

Integrated neural network

Morphing materials

3D prints Holographic technology

Energy Harvesting

Ecological Materials

GROUND OPERATION An autonomous renewably-powered taxiing carriage to be ready at ground.

Quicker transportation of aircraft from runway.

Faster turnaround of aircraft

Operation of ground vehicles without human intervention.

OUR THOUGHTS ON FUTURE AVIATION1)Aviation with solar

power2)Flight based on free

energy3)Flying cars4)Flight without pilot5)Improved systems to

reduce death during crash

6)Reduction of pollution during flight

7)Eco friendly flight
