Welcome to this rocket building site. You are going to build the rocket with Easy Java Simulation , a free physics authoring toolkit.With Easy Java Simulation , you can create simulations which others can modify too. In essence, You are now creating an "editable" simulation.


Physics will no longer be the same as you embark on your journey to create Rocket simulation. Use your Physics concepts to make your Rocket Simulation as realistic as possible. Have fun!

Steps:

download EJS_4.3.7_130930.zip , unzip and run (click on EJSConsole.jar):

not recommended as it cannt run in your school computers EJS_5.0_beta_130912.zip, but you can try it at home.
Pre Installation: assume you have Java else use this link http://java.com/en/download/index.jsp

Installation: Java 3D 1.5.1 2.95 MB java3d-1_5_1-windows-i586.exe may require downloading from their website due to license agreement. http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-java-client-419417.html#java3d-1.5.1-oth-JPR Look for Allen to install 3D Java on your lap tops

Engage: 

1. You are a Hillgrove Secondary young computer engineer(s) or scientist(s) working in a group of 2, for the Singapore Space Program and your special assignment is to develop and implement a computer model to simulate a rocket being launched to the International Space Station (ISS) which is orbiting at an altitude of 355 km. The values of the parameters for one specific rocket are provided here, but your program should be constructed such that a user will easily be able to enter different values of these parameters to simulate different rockets.

   The (ISS) International Space Station, as seen from Space ShuttleEndeavour in May 2011. https://en.wikipedia.org/wiki/International_Space_Station

2. The rocket that is going to be used for the launch that you are assigned to simulate has the following properties:
1. Empty mass (with no fuel and no payload) is 10,000 kg
2. Maximum fuel capacity is 10,000 kg of rocket fuel
3. Exhaust velocity is 7000 m/s
4. Burn rate is 100 kg/sec
5. Reference area (of the front of the rocket) is 10 m2
6. Drag coefficient is 0.5
3. Your superiors want to know answers to a few questions including:
1. Can this rocket reach the ISS?
2. Using the rocket’s full fuel capacity, what is the maximum payload in kilogran that could reach the ISS?
3. convince your fellow engineers and scientists that your computer model is a close reflection of the real world situation with models that shows graphs of height versus time (already in template), velocity versus time, and force versus time etc.
