What is the tear-drop

100

First true powered flight was in this.

What is a hot air balloon

100
Aero

What is : pertaining to air

100

He discovered that the pressure of a fluid in motion drops when the fluid accelerates.

Who is Daniel Bernoulli

200

Chinese sailors attached to kites for military observation was the first "manned aircraft" seen by this man.

Who was Marco Polo

200

Name all five parts of the wing.

What is the Leading Edge, Trailing Edge, Upper Camber, Lower Camber and the Chord

200

The three things on the hot air balloon cockpit instrument panel that tells the vertical speed, the temperature inside and outside the balloon, and the height the balloon is flying.

What is variometer, temperature gauge or thermistor, and altimeter

200

Votex

What is: a spinning column of air that is created behind the wingtip as a result of air moving from an area of high pressure  to low pressure

200

Sir Isaac Newton's three laws of motion. And as a bonus: which one relates to airplane's lift?

What is:

1. object at rest will stay at rest

2. an object moves in the direction of the applied force

3. For every action there is an equal and opposite reaction

300

Increasing the angle of attack also increases this.

What is lift

300

This type of air is more dense. (warm or cold)

What is cold air

300

These panels made of nylon and dacron are sewn together and can withstand high temperatures and are coated with additives to make them resistant to ultraviolet sunlight damage.

What are gores

300

Envelope

What is the main body of the balloon

300

This is where we get the energy for our atmosphere to move horizontally and vertically.

What is the Sun

400

Four forces that act on an airplane in flight.

What is lift, gravity, thrust, and drag....

For bonus points: which two are natural forces and which two are artificial? 

400

Air flow on top of an airplane wing moves in this way as compared to the air flow below the airplane wing.

What is faster and further
400

Hot air balloons operate on this principle. 

What is buoyancy 

400
Thermal

What is: a column of air that moves upward

400
The pitch is the  up and down motion of an airplane which is controlled by the elevators, the yaw cause the airplane to turn right or left which is controlled by the rudder pedals, and the roll tips the plane side to side and is controlled by this.

What are the ailerons

500

Name the three axes of an airplane. 

What is vertical, lateral, and longitudinal. 

For bonus points: Name the movement (roll, pitch, yaw) associated with each axis.

500
These increase lift and increase drag and are helpful during take-off and landing.

What are flaps

500
These brothers created the first manned hot air balloon.

Who are Joseph and Etienne Montgolfier

Dynamic

What is: forces in motion

500

The force that an engine propeller creates.

What is thrust
