NATIONAL MATH and SCIENCE STANDARDS
EngineSim meets many of the National Mathematics and Science Standards.

National Mathematics Standards: Mathematics as Problem Solving, Mathematics as Reasoning, Mathematical Connections, Algebra, Functions, Geometry from an Algebraic Perspective, Trigonometry, Discrete Mathematics, Conceptual Underpinnings of Calculus, Mathematical Structure.
National Science Standards: Science as Inquiry, Physical Science, Life Science, Science and Technology, Science in Personal and Social Perspectives.

EngineSim was developed at the NASA Glenn Research Center in an effort to foster hands-on, inquiry-based learning in science and math. EngineSim is a simulator that models the design and testing of jet engines. The program works in two modes: Design Mode or Tunnel Test Mode. In the Design Mode, you can change design variables including the flight conditions, the engine size, the inlet performance, the turbo machinery compressor and turbine performance, the combustors or burner performance, or the nozzle performance. For a turbofan engine design you can also vary the fan performance and the bypass ratio. When you have a design that you like, you can switch to the Tunnel Test Mode, where you can vary only the flight conditions (airspeed, altitude, and throttle setting).

DOWNLOAD YOUR OWN COPY:
At the request of several users, we are making EngineSim available for downloading onto your computer. Here is the procedure to follow:

  1. The downloaded file is in .ZIP format which you must store on your hard drive when prompted by your browser.
  2. Click Here to download a copy of Version 1.8a, EngineSim Applet
  3. Go to the directory where you have stored "EngineSim.zip" and open the program "WinZip".
  4. "Extract" all the files. If you skip this step, you will only see a grey box when you attempt to run EngineSim.
  5. Click on either Turbo.html or EngineSim.html to launch your browser and load the EngineSim driver program. Turbo.html is intended for experienced users and launches the program alone; EngineSim.html includes instructions on program operation.

RangeGames: This program uses jet engines to present a variety of math and physics problems. RangeGames includes a "Play Mode," in which nothing is recorded; a "Learn Mode," in which you will get several tries at determining the correct answer; and an "Exam Mode," where you get one chance and your answer is recorded for your teacher.

Rate and force problems of different levels of difficulty are included. These are targeted for the high school student. The rate problems deal with how far and how long an airplane can fly on a given amount of fuel. The force problems deal with Newton's laws of motion on takeoff. Graphical feedback is given for each answer choice.
