Rockets: introductionSPACE SHUTTLE ENDEAVOUR
Radar Topography Mission: mapping the earth
You are about to watch a launch of Endeavour from Feb.11, 2000.As you watch, pay close attention to what the announcer says, and answer the questions on worksheet #1.

This video footage of the MRHS rocket launch was shot in April 2000. Of the three classes who launched, the record altitude was
about 400ft. As you will see, many rockets didn’t go nearly that far.
See if you notice something else which should have happened, but didn't for many of the rockets...

Aerodynamics =
the characteristics of
the outer body of a
vehicle, aircraft, etc.,
that effect the
efficiency with which it
moves through the air.
The following pictures were
taken from

Because it's difficult to see whether air flows smoothly over an
object, different methods are used to show the air's path. Here, oil-
flow visualization is used to test the aerodynamics of the wing
shape on this aircraft design.
Can you see a potential
problem area?

The aerodynamic development of trucks in wind tunnels has had a
major impact on truck fuel consumption. Here, a one tenth scale
model illustrates the use of smoke flow visualization to see
whether the truck's shape is aerodynamic.
Where is the
problem on
this vehicle?

In some sports, an aerodynamic body shape is
important. This Canadian national ski team member is
using a small wind tunnel to adjust her posture, and
possibly shave seconds off her race time.

Aeronautical engineers test their designs to make sure their
shape is aerodynamic by testing small models first.
This model of a NATO/AGARD generic fighter aircraft
passed the test, and the full-size craft has been built.

Models are used to test different aspects of flight
operation. This model of a Bombardier Global Express
aircraft is undergoing thrust-reverser simulation tests.
Note the shape of the NOSE of this aircraft...does it
remind you of anything?

Should the junction
between your nose-
cone and rocket body
be smooth?
In this wind-tunnel test,
air flow is illuminated
in blue, and shows the
formation of a vortex of
air on either side of the
test object.

Before you go on to design your rocket fins and nose cone, answer the
questions on worksheet #2.

Recovery device (RD) - slows the descent of your rocket, and prevents it
from being broken.
Shock chord - connects the rocket's nose-cone to the body after
deployment of the RD. Elasticity absorbs some of the force as the RD
and nose cone are expelled.
Eye screw - connects RD, nose cone, and shock chord.
Wadding - added AFTER the rest of the rocket has been assembled. It
protects the RD from burning.
Thrust ring - prevents the engine from being propelled up through the body of
the rocket during launch.
Launch lug - threads onto guide wire on launch pad to position rocket for launch.
Engine -controls rocket launch and flight.
Engine clip - keeps engine from falling out of the rocket body.

One way to gage your rocket's success on launch day is to calculate its final altitude.
