Aviation unit 2 Questions and Answers
100% Pass
Birds generate ——— by flapping there wings ✔✔Lift and thrust
What does a camver of an air foil refer to ✔✔The curve of the wing
Which concept best illustrates the mechanics, flying, hot air balloon ✔✔Density and buoyancy
Which of the following represents contribution, Greek myths, made to civilization today ✔✔Inspiration for human flight
Which of the following best explains why wind tunnels are used in the testing the design of aircrafts? ✔✔To test scale models in air foils in aircraft
Leonardo da Vinci flying machine in the orthopter was an invention to this ✔✔Flapped it's wings like a bird
For modern day gliders did what Bernoulli's principal demonstrates? ✔✔It removed faster over the top of the wing in the air below the wings
Hot air balloons rise ____ lifting the balloon ✔✔Becomes less defense
What part of the bird most resembles the propeller on a aircraft ✔✔Wings
When the four forces of flight are balance the flying object is said to have ——— ✔✔Equilibrium
What is the purpose of the burner of a hot air ballon ✔✔It gets then air inside the balloon causing it to rise
In early aviation research which was the most important contribution of sir George cayleigh ✔✔Described the underline principles and forces of flight
Why dis the wright brothers include a rutter in their airplane design? ✔✔To prevent the glider from spinning out of control
Explain how hot air balloons crest left ✔✔Hot air balloons experience lift due to arch principal because hot air is less dense and thus more buoyancy then cooler air
What the wright brothers learn from building a wind tunnel ✔✔The wright brothers built a wind tunnel to study why their air foil designs did achieve the same theoretical lift predicted by autto Lilienthal and others
Explain how the wright brothers used the engineering practices to successfully achieve life when other engineers failed ✔✔They started by delivering by understanding the controlling their aircraft was the hardest challenge they knew what question to focus their energies on
Explain how Ancient Greek stories modern in aviation ✔✔They inspired humans to build flying machines
Humans have watched birds fly and tempted to imnalute the use of wings and flight
Stories been told in literature, art and science
How gliders produce lift even though they don't have engines ✔✔A glider produces thrust by converting potential energy into kinetic energy
As the glider falls it's gravitational potential energy is converted into kinetic energy this increases the gliders speed
