Fundamental Terms
Activity
If so instructed
by your teacher, print out a worksheet page.
In order to understand
the concepts of jet engines, you must first understand the concepts
of flight and Newton's Three Laws of Motion. Along with Newton's Laws
you will cover six terms that are basic to flight. The terms are hyperlinked
to the Beginner's
Guide to Aeronautics. Before going to these descriptions review
the worksheet. It will assist you while reading each section. The terms
are:
THRUST
DRAG
VORTICES
LIFT
WEIGHT
STREAMLINES
NEWTON'S
LAWS:
1st
- LAW of INERTIA
2nd
- LAW of ACCELERATION
3rd
- LAW of INTERACTION
After you feel comfortable
with the provided information, complete this matching exercise.
|
1. ___
|
This decreases
when the spoilers are used.
|
A. Weight
|
|
2. ___
|
The faster
the air is pushed through the jet engine, the more forceful
this is.
|
B. Newton's
First Law
|
|
3. ___
|
This, along
with weight, acts as resistance to aircraft motion.
|
C. Vortices
|
|
4. ___
|
If thrust
is greater than drag, this law describes the increase in velocity.
|
D. Streamlines
|
|
5. ___
|
When thrust
and drag are in balance, this law explains why the aircraft
has a constant velocity.
|
E. Newton's
Second Law
|
|
6. ___
|
Jets produce
thrust through the application of this law.
|
F. Thrust
|
|
7. ___
|
For an aircraft
to fly, the lift must be greater than this force.
|
G. Lift
|
|
8. ___
|
This is
described as the flow of air along a smooth path.
|
H. Newton's
Third Law
|
|
9. ___
|
This swirling
flow occurs near the wing tips.
|
I. Drag
