Comprehension Questions


Chapter 2: Five Years to Flight: 1903


Answer Key

Directions After reading Chapter 2, Five Years to Flight: 1899, answer each question using complete sentences. Back up your answers by using information from the book.

1. How did Wilbur get information about flight?

He wrote a letter to The Smithsonian Institution requesting all the information they had acquired on flight.

How would we go about finding information on flight today?

We could use these resources:
library, Internet or Web, Flight Associations or agencies (FAA or NASA), books, magazines, newspapers, videos, CD-ROMs.

2. Why do you think Wilbur suddenly decided to head in a new direction?

Perhaps he was bored with the cycle shop and needed a change or a new problem to solve or challenge in his life.

3. On a separate piece of paper, create a chart that summarizes each of the 13 aeronautical entries mentioned by the author. Use the headings below to help plan your chart.

Individual Time Period Place Achievement
Daedalus legend Greece made wings of feather and wax and flew, but crashed
Chinese 500 BC China propeller driven toy kites
R. Bacon 1200 England wrote about ornithopters (flapping wing devices)
St. Joseph 1600 Italy said to fly using spiritual powers
da Vinci 1300 Italy designed plans for flying machine
Danti 1490 Italy tower jumper
Oliver 1000 England tower jumper
Bocqueville 1742 France human glider
Montgolfier 1783 France hot air balloon
Cayley 1804 England glider
Henson/Stringfellow 1844 England fixed wing flying machine with propellers-(model)
Stringfellow 1844 England improved the model above, but made it smaller
Lilienthal 1890s German man-carrying gliders
Chanute 1890s US designed gliders and wrote a book which compiled all aeronautical research acquired
Hargrave 1893 Australian developed box kite used to research aircraft wings
Langley 1896 US built scale models of flying machines (aerodomes)

4. After the Wright Brothers read through all the material, what three problems did they decide needed to be solved in order to have a successful flight? List them.

  1. Wings are needed to lift an airplane into the air.
  2. An engine had to move the airplane through the air once it was airborne.
  3. The pilot needed to be able to control the aircraft's movement once it was airborne.

5. Which one of the three problems seemed to the brothers to be the toughest to solve? Why do you think it was so tough to solve?

The problem of control. No one else seemed to have designed a way to control an aircraft, because most of the inventors of the time were still trying to get an aircraft to fly.

6. How did the brothers go about solving the problems?

They created systematic experiments- each experiment led to another. They were observant and kept detailed records of the results. They did not want to experiment by trial and error.

7. What two problems did they work on first and what were the solutions for each?

Problem 1: They first wanted to figure out how to control the aircraft's balance so that it would not tip and crash in a gust of wind.
Solution: To balance the wing lift they put a smaller, flat horizontal flap in front of the wings which could be raised and lowered. They called it a "horizontal rudder" (it was used like the present-day control surface: elevator). It controlled the pressure of air moving along the wings to keep the pressure balanced from front to back.
Problem 2: Side-to-side balance of the aircraft.
Solution: Twist the wingtips so that one would twist upward and the other would twist downward to counterbalance any change in the airflow. They called this "wing warping."

8. How did they try out their ideas?

They created a boxkite structure with bamboo struts and wires attached to the wing tips and flew it like a kite. They manipulated the wingtips with the wires to control and balance the kite.

9. What kind of test site did the brothers look for? Where did they go to find this information?

test site: steady winds and smooth, treeless surface
source: Weather Bureau
