QuickStart

Install RocketCEA

The easiest way to install RocketCEA is:

pip install rocketcea

    OR on Linux
sudo pip install rocketcea
    OR perhaps
pip install --user rocketcea

Getting Help

After installing with pip, there will be a launch command line program called rocketcea or, on Windows, rocketcea.exe.

From a terminal or command prompt window simply type:

rocketcea

Your browser will launch with these RocketCEA help pages.

Running RocketCEA

Any use of RocketCEA begins with an import statement and an instance of CEA_obj:

from rocketcea.cea_obj import CEA_Obj
C = CEA_Obj( oxName='LOX', fuelName='LH2')

In the above example, LOX and LH2 are called out, but any propellants on the Propellants page can be used.

There are a large number of examples included in this document

For instance, look at LOX/LH2 Performance on the Standard Examples page.

Highlight the source code with your mouse, right click the highlighted code and select Copy.

Paste that code into your text editor and save it to a python file.(for example D:/rocketcea/example_1.py).

At a command prompt, navigate to that subdirectory (D:/rocketcea in the example above) and give the command:

python.exe example1.py

In many text editors, hitting the F5 key will execute the code.
