DEVELOPMENT OF AIRCRAFT

                       DEVELOPMENT OF AIRCRAFT

EARLY HUMAN EFFORTS ORNITHOPTERS

Early humans tried to fly by imitating the birds by flapping a pair of wings . proved ineffective for large scale flying machines.

MAJOR BREAKTHROUGH 

George Cayley

he was a pioneer of aeronautical engineering and is sometimes referred to as "the father of aviation" designer of the first glider to carry human being aloft 

control flight 

Otto Lilienthal 

the first person to male well-documented , repeated ,successful gliding flights .

wright brothers

the brothers ' fundamental breakthrough was their invention three-axis control ,which enabled the pilot to steer the aircraft effectively and to maintain its equilibrium .this method became and remains standard on fixed -wing aircraft of all kinds.
wright brothers focused on developing a reliable method of pilot control as the key to solving 
"the flying problem"

FIRST POWERED FLIGHT 

Major structural stresses 

Stresses on the wings, fuselage, and landing gear of aircraft are tension, compression, shear, bending, and torsion. These stresses are absorbed by each component of the wing structure and transmitted to the fuselage structure.
