Looking back on aviation history, who do you think made the first successful attempt? Who invented the airplane? Or was it an accumulative effort?
People have been fascinated with flying in the sky since the beginning of age, countless drawings, carvings and relics clearly show this fascination. But who took this fascination to the next level? Who decided to take this dream to the vast skies and invent the first airplane?
Let’s take a journey through the history of aviation and learn who invented the airplane.
Lighter than air
Francesco Lana de Terzi published a theory in 1670 which suggested using copper foil spheres containing a vacuum for lighter than air lift. Such spheres would be lighter than the surrounding air, enough to lift an airship.
Albeit theoretically sound, unfortunately his design was not possible as the pressure of the surrounding air would crush the spheres if they contained nothing but vacuum.
This theory, known as vacuum airship, remains an unfeasible dream with any current materials. Nonetheless, we cannot ignore Terzi's effort when discussing who invented the airplane.
In the 18th century, the hydrogen gas was discovered, finally a substance lighter than air! This led to the invention of the hydrogen balloon. The Montgolfier brothers began manned flights of the hot-air balloon at the time.
On November 21st, 1783 the Montgolfiers launched the first free flight with human passengers. The balloon was powered by a wood fire. It drifted for 8 km.
The use of balloons for military purposes began at the end of the 18th century. The French government established Balloon Companies during that era.
The foundation of modern aerodynamics started around the same time as a result of diverse theories in mechanics, particularly fluid dynamics and Newton's laws of motion.
Airships or dirigible balloons
Work on developing a steerable or dirigible balloons continued throughout the 19th century. The first powered, controlled, sustained flight took place in 1852 when Henri Giffard flew 24 km in France using a steam engine driven craft.
Even though airships or dirigibles were used in World War I and II, and continue to be used to this day, even if on very limited basis, their development has been outshined by heavier-than-air aircraft.
Sir George Cayley, the father of the aeroplane
Cayley was the first to identify the four forces that influence any aircraft: thrust, lift, drag and weight. He was also the first to design a heavier-than-air aircraft, and he focused on stability and control in his designs.
He designed a manned glider or "governable parachute" capable of launching from the top of a hill. This glider carried the first aviator across Brompton Dale in 1853.
The Wright brothers
With impressive determination the Wright brothers worked their way methodologically through gliders and into building the first airplane. The Wrights made the first sustained, controlled, powered heavier-than-air manned flight on December 17th, 1903.
Their first flyer was unsteady and unreliable, but the brothers did not quit, they made Flyer 2 and Flyer 3. Flyer III became the first practical aircraft in history, flying steadily under full control, bringing its pilot back and landing safely.
After the rough start, aviation developed in leaps. Almost immediately airplanes were used for military uses, which resulted in impressive growth in a short time.
The era between World War I and World War II witnessed amazing progression in aircraft technology. Airplanes started evolving from low-powered biplanes made from wood and fabric to sleek, high-powered monoplanes made of aluminum during that time.
The development might have started for military reasons, but commercial aviation certainly benefited from the impressive progress.
After World War II, the United States started investing in manufacturing plans capable of producing commercial aircrafts with competitive prices that allow for passenger use.
