3. When did the era of modern aviation begin and why?
Modern
aviation began with Sir George Cayley, in the early-to-mid-1800s. He determined
that heavier-than-air flight was something that could be achieved once enough
scientific research was completed. He worked on learning basic principles of
aerodynamics and was essentially the first aeronautical engineer. The flyers
that he built were the first fixed-wing gliders, giving humans a taste of
flight (Crouch, 35). He had been fascinated with balloons and flying toys as a
child, which is what sparked his inspiration. In turn, his efforts sparked both
European and Americans to continue what he had started. The Wright brothers
were well familiar with his work and greatly praised his academic publishings
on the principles of aeronautics. His research helped others to take what he
had learned and apply new concepts to the matter of flight.
4. What three methods of solving the challenge of flight
emerged by the late nineteenth century and how effective were they?
The
first approach was when experimenters went straight from research to the
construction of a fully-function aircraft. One example of this is Clément Ader
from France, who designed a steam-powered tailless monoplane. His creation
basically rose in the air for 160 feet, but did not have a sustained or a
controlled flight (Crouch, 41-42). Another approach was focused on designing
and testing model aircraft. Alphonse Pénaud invented a “planophore” which was
powered by twisted rubber bands. The research from some of his designs inspired
Wilbur and Orville Wright. The third approach was to design and test
specifically piloted gliders. Between the years 1849-1890, at least five people
glided for short distances (Crouch, 44). Soon after their flights, however,
they all went back to their research and did not attempt the dangers of flying.
7. When and what was La Grande Semaine d’Aviation de
Champagne and what significance does it have in aviation history?
This
was a week of flying activity, just north of the city of Reims, France. It was
held in August of 1909. There were competitions to be held and passenger rides
to be given. Many different airplanes made their appearance, and the pros and
cons of each were examined. This event was a demonstration of the technology
that had developed. One big significance that is has in aviation history is
that it was the first international public flying event. The book states that
this event was the transition between inventing the airplane and the birth of
the aviation industry (Crouch, 118).
