Subject Area: Mathematics and Technology
Grade Level: 9-12
National Standards:
Mathematics
- Use and value the connections between mathematics and other
disciplines.
- Construct and draw inferences from charts, tables, and
graphs that summarize data from real-world situations.
Technology
- Technology Research Tools - Select and apply
technology tools for research, information analysis,
problem-solving, and decision-making in content learning.
- Technology Problem-Solving and Decision-Making Tools
- Routinely and efficiently use on-line information resources
to meet needs for collaboration, research, publications,
communications, and productivity.
Objectives:
- After reading the explanation given below, use the World Wide
Web to access additional information needed to complete the
activities on the forces on an airplane, the function of the
stabilizer, and the calculation of Mach speed, temperature,
pressure, and thrust at different altitudes and speeds.
- Use graphs to observe trends and draw conclusions.
- Using an aircraft design package found on the World Wide Web,
design an aircraft to fly non-stop from San Francisco to New York
with the goal of having as low a ticket price as possible.
Propulsion Systems
Analysis (http://www-psao.grc.nasa.gov/) is the division of NASA
Glenn Research Center that explores, through computer programs and
mathematical analyses, the overall performance and economic potential
of advanced and unconventional propulsion systems of subsonic, supersonic,
and hypersonic vehicles. For aircraft and
aircraft propulsion systems analysis, the "desired end" is obtaining
the best performance with the least weight and the least cost.
The Beginner's
Guide to Propulsion is a Web site of information prepared at
NASA Glenn Research Center to help you better understand how
aircraft propulsion systems work. You will access several of these slides for background
information on the effects of altitude on engine performance.
You will also learn how to calculate the
Mach Number
for subsonic and
supersonic airplanes.
To begin the activity, click on Propulsion
System Analysis Activities.
Assessment:
You, or you and your partner(s), will be evaluated on the
feasibility of your answers.
Evaluation:
You will be able to use the Internet to find additional
information needed to complete the activities on aircraft
propulsion and calculating Mach
number, temperature, pressure, and thrust at different altitudes.
You will use graphs to observe trends and draw conclusions.
