Guide to Propulsion
Thrust to Weight Ratio
Subject Area(s): Mathematics (Pre-Algebra)
as Problem Solving - Apply integrated mathematical problem-solving
strategies to solve problems from within and outside mathematics.
Mathematics as Communication - Formulate mathematical definitions
and express generalizations discovered through investigations.
Algebra - Use tables and graphs as tools to interpret expressions,
equations and inequalities.
Statistics - construct and draw inferences from charts, tables,
and graphs that summarize data from real-world situations.
Technology Research Tools - Routinely and efficiently use on-line
information resources to meet research needs.
Tools - use content-specific tools, software and simulations (e.g.,
environmental probes, graphing calculators, exploratory environments,
Web Tools) to support learning and research.
Problem-Solving and Decision-Making Tools - Routinely and efficiently
use on-line information resources to meet needs for collaboration,
research, publications, communications, and productivity.
an explanation from a NASA Web site called The
Beginner's Guide to Propulsion, you will demonstrate an understanding
of the text by completing a worksheet on thrust to weight ratios.
Beginner's Guide to Propulsion is a Web site of information prepared
at NASA Glenn Research Center to help you better understand aircraft
engine propulsion. Click the Beginner's
Propulsion Index to access the list of slides. Go to the bottom
of the page and click on the yellow button that gives you the Short
Index. Open the slide called Thrust
to Weight Ratio under the heading of Aircraft Motion and read the
explanation. Then using the background information given at Thrust
to Weight Ratio Activity, complete the worksheet designed to demonstrate
your ability to research data on the Internet, complete a table, and
calculate ratios using the appropriate numbers.
you and your partner(s), will be evaluated on the accuracy and/or feasibility
of your answers.
