Mission
Part
One: Crew
Exploration Vehicle Design Essay and Graphic
Now that
you have studied the systems of the Space Shuttle
designed in the 1970s, put yourself in the engineer's
seat. Design a 21st century Crew
Exploration Vehicle. Submit a drawing along with
a one-page written description (at least 500 words).
List all the sources you use.
You
will need to describe the following systems when
you design a future Crew Exploration Vehicle:
- Propulsion
- Guidance
- Life support
- Landing
- Emergency
systems

Two: Shuttle Math The
Deorbit Burn: Part Two
|
Using the change (delta) in velocity that
must be used to lower the perigee to a 60-mile
altitude (This was your answer to the Shuttle
math question for Lesson 1) and assuming
the Orbiter's OMS engines have a combined
force (thrust) of 12,000 lbs and the Shuttle
has a weight of 250,000 lbs (with a full cargo
bay), use the equations below to compute the
length (or time) of the burn necessary in
minutes.
f
= ma force equals mass times acceleration
and t = v/a time equals velocity
divided by acceleration
Your acceleration will be in G's,
where 1 G = 32 feet per second per second
(this is how far an object travels due to
the force of gravity in a vacuum).
Hint:
You can also use English slugs instead
of G's. 1 slug = 32 pounds. This makes the
equation somewhat simpler. Mass of the Orbiter
= 250,000/32 slugs.
