From the age of ten, Cayley began studying the physics of bird flight and his school notebooks contained sketches in which he was developing his ideas on the theories of flight. It has been claimed [ 59 ] that these sketches show that Cayley modeled the principles of a lift-generating inclined plane as early as 1792 or 1793.
Flapping flight is limited by the size and muscle force of a wing. Even while using the correct model of arboreal or cursorial, protobirds' wings were not able to sustain flight, but they did most likely gain the behaviors needed for the arboreal or cursorial model like today's birds do when hatched. There are similar steps between the two. [19]
Reaching a scientific understanding of the principles of bird flight. Scientific aerodynamic experiments were conducted to demonstrate drag and streamlining, movement of the center of pressure, and the increase in lift from curving the wing surface. Defining the modern aeroplane configuration comprising a fixed-wing, fuselage and tail assembly.
Invented the autogyro, the predecessor of the modern helicopter (9 Jan 1923). [17] [18] De la Cierva's flapping hinge overcame the problems of early rotor-winged flight, and is the basis of the modern helicopter rotor.

They conducted several tests, but Orville made the first flight at 10:35 a.m., lasting 12 seconds and traveling 120 feet. Wilbur flew it the longest that day for 59 seconds and across 852 feet.
Worried that it will set fire to the curtains, servants end its flight by dashing it to the ground. It is the first known demonstration of a practical lighter-than-air craft. [1] 1716. Well thought-out glider-project of the Swedish scholar Emanuel Swedenborg. Basis for his construction are bird flight and the glider kite. 1738
First flight in a steerable balloon (or airship): On July 15, 1784, the Robert brothers (Les Frères Robert) flew for 45 minutes from Saint-Cloud to Meudon with M. Collin-Hullin and Louis Philippe II, the Duke of Chartres, in an elongated balloon designed by Jacques Charles, following Jean Baptiste Meusnier's suggestions (1783–85), but the ...
