Hot Air Balloons
How do pilots steer hot air balloons?
By moving into different wind currents at different altitudes.
The Wright Brothers weren't the first to fly but they were the first to develop THIS kind of aircraft.
There are 3 qualities.
Heavier than air, controlled, powered aircraft
What are the four forces of flight?
Lift
Drag
Thrust
Weight
Birds!
What is the school mascot?
Falcons!
What is the purpose of the burner in a hot air balloon?
To heat the air inside the envelope
What force did the propellor on the Wright Flyer generate?
Thrust
What does the camber of an airfoil describe?
The curvature of the airfoil
Why did Icarus and Daedalus try to fly?
To escape from prison!
Whose glider dented the wall?
Nick and Jose
By releasing hot air through the parachute valve at the top of the balloon.
Demonstrate the motions of pitch, roll, and yaw
pitch is tilt up or tilt down
roll is lean left lean right
yaw is turn left or turn right
What do birds generate when they flap their wings?
Lift and Thrust
How did da Vinci's Ornithopter generate thrust?
Flapping!
What noise does an ambulance make?
Wee woo
Why does a hot air balloon fly? Use the words density and buoyancy in your answer
The air inside the balloon is hotter and therefore less dense than the outside air. This makes the balloon buoyant, causing it to rise.
What is the purpose of the rudder on an aircraft? What motion does it control?
What forces do we measure in wind tunnels or simulations?
Lift and drag
Who first described the four forces of flight?
- The Wright Brothers?
- George Cayley?
- da Vinci?
Which fish is best fish?
Carp
What is Archimedes' Principle?
The buoyant force on an object is equal to the weight of the fluid displaced by that object.
Which part of the aircraft did the Wright Brothers test and develop using a wind tunnel they built?
The airfoil or wing
When all of the forces are balanced on an object in flight, it is said to be in ___________ .
Equilibrium
How does Bernoulli's Principle explain how an airfoil generates lift?
Air moves faster over the top of the airfoil, creating low pressure.
Air moves slower under the airfoil, creating high pressure.
Lift forces the airfoil up from the area of high pressure to the low pressure.
What is the Rizzler's government name?
Christain
