Activity

Worksheet

Answers

Beginner's Guide to Propulsion
Turbine Engine Parts -Inlets
Subject Area: Mathematics (Pre-Algebra, Geometry)
Grade Level: 7-9

National Standards:

Mathematics
Mathematics as Problem Solving - Use, with increasing confidence, problem-solving approaches to investigate and understand mathematical content.
Mathematics as Communication - Reflect upon and clarify their thinking about mathematical ideas and relationships.
Algebra - Represent situations that involve variable quantities with expressions, equations, inequalities, and matrices.
Geometry - Represent problem situations with geometric models and apply properties of figures.

Technology

Research Tools- Use content-specific tools, software and simulations (e.g., environmental probes, graphing calculators, exploratory enviromnets, 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.

Objectives:

After reading 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 relating to the cross-sectional areas of turbine engine inlets.

The 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 Beginner's Guide to Propulsion to access the list of slides. In the "Short Index" under the heading of Turbine Engine Parts, click on the slide called Inlets. Read the explanation to see how inlets apply to the propulsion of an airplane. Using this information, complete the Inlet Activity to demonstrate your ability to complete calculations on cross-sectional areas of inlets.

Assessment:

You, or you and your partner(s), will be evaluated on the accuracy and/or feasibility of your answers.

Evaluation:

You will demonstrate the ability to calculate the area of a figure and see how it relates to engine inlets and airplane propulsion.
