Guide to Propulsion and EngineSim
Density Subject Area: Chemistry Grade Level: 9-12 Time Required: 3 class periods National Standards:
Objectives:
EngineSim, which was created at NASA Glenn Research Center to illustrate an example of their research, simulates the aero-thermodynamics of a jet turbine engine. With this software you can learn about different types of jet engines and how they work. You can change the operating conditions and even design your own turbine engine. EngineSim is intended for science and math students from secondary schools through undergraduate engineering. In some parts of the package, there are problems that you must solve using EngineSim. In other parts, you are free to experiment. EngineSim is a Java applet which you can also download from the World Wide Web at EngineSim Download. The Beginner's Guide to Propulsion is a Web site of information prepared by the NASA Glenn Research Center to help you better understand aircraft engine propulsion. Click on the Beginner's Guide Index to access the list of slides. Open the slides entitled Air Properties Definitions and/or Air Density. Read the descriptions as background information to help you complete the activity. Notes: A. Because
the target group is a Chemistry class, the lesson is presented with a
rather open procedure by design. Students are not told step by step exactly
what to do. They are given the objectives and in small groups are to decide
what materials, information, and procedures are required to determine
the mass of the gas molecules in the room.
Assessment: You and your group will be assessed on your description of your procedure, the presentation of your data and calculations, and the final results for both the mass of gas molecules in the classroom and the functioning of the jet engine. Evaluation:
