Objective:
After reading
an explanation from the NASA Webbased "textbook", The Beginner's Guide
to Aerodynamics, you will use the information in combination with
data from other Web sites to solve single variable equations for distance
(range), time, and velocity.
The Beginner's Guide
to Aerodynamics is an online "textbook" developed by the NASA Glenn Research Center
in Cleveland, Ohio. Click on the Beginner's
Guide Index to access the list of slides. Open the slide called Range
 Constant Velocity. Read the information on this page. Pay special
attention to the four forces affecting an airplane. Open the link Unbalanced
Forces and observe the animation of how flight is affected by the change
in these forces. When these force are equal, the airliner is said to be
a Cruising Airliner and velocity
is a constant. If we assume the condition of a cruising airliner, then we
can calculate velocity, distance (range), and time using the equation given
on the top of the Range page. This
equation is d = V t .
Assessment:
You, or you
and your partner(s), will be evaluated on the feasibility of your answers.
Evaluation:
Using the
information presented in the Beginner's Guide in combination with data
collected from other Web sites, you will solve equations for the variable
of distance (range), time, or velocity when the other two variables are
known.
