Home Chemistry - Aerodynamics

Aim: To learn about flight and aerodynamics.

Definition of Aerodynamics:

Aerodynamics is the way air moves around things.
The rule of Aerodynamics explains how an airplane is able to fly.
Anything that moves through air reacts to Aerodynamics.
A rocket blasting off the launch pad and a kite in the sky reacts to aerodynamics.

4 forces of flight:

The four forces are lift, thrust, drag, and Weight (gravity).

• Weight is the force of gravity. It acts in a downward direction -
• towards the center of the Earth
• Lift is the force that acts at a right angle to the direction of motion through the air.
• Thrust is the force that propels a flying machine in the direction of motion.
• Engines produces thrust.
• Drag is the force that acts opposite to the direction of motion.

Paper Plane:

Material:

1. Paper

2. Scissors

Steps:

1. Take your paper and fold it in half

2. Then make a house shape and fold the two ends onto the line

3. And fold it like a normal plane and your done

Findings:


Plane Type:

Distance
Behaviour
Normal

Plane type	Distance	Behavior
Normal	3.9	It went straight
Ailerons	1m	Curved to the left
Paper clip	5	Straight

Conclusion:

For this experiment I learnt what Aerodynamics means, and I also learnt what the 4 forces are.
We also found out that the normal paper plane flew 3.9m straight.
The Ailerons Paper Plane flew 1 m straight but then it curved to the left.
Also when using the paper clip it flew 5 m Straight that it even hit the door!
Here are some information about the 4 forces that I have learnt about today.
The four forces are lift, thrust, drag and Weight (Gravity).
Thrust directs the plane to where it is heading, for example the plane is to
turn right or left then the thrust will direct it to the directed ways.
Weight is the force of Gravity. It acts in a downwards direction. For example if you pass
the ball to someone and it goes upwards then It will come back down, that is Gravity.
Lift is the force that acts at a right angle to the direction of motion through the air.
For example Lift helps the plane stay in the air.
Drag is the force that acts opposite to the direction of motion
I've enjoyed doing this experiment it has taught new interesting things that I've never knew before about.
