An open source,
platform-independent,
flight dynamics model in C++

Aeromatic

version 0.96
This form can be used to create aircraft configuration files for use with the JSBSim Flight Dynamics Model, the default FDM for the FlightGear, Outerra and OpenEaagles (etc.) flight simulators. The configuration file format produced using this utility is version 2.0, and is incompatable with older formats because of an extensive overhaul of JSBSim's XML code that occured in December of 2004.

You will need at least two files for a complete configuration, an aircraft file containing information on the aircraft's mass properties, propulsion, flight control, aerodynamic properties, etc., an engine file describing the engine(s), and in the case of a propeller-driven aircraft you will need a prop file. Aeromatic will generate plausible configuration files for your aircraft using some simplifying assumptions. Note that Aeromatic allows only one type of engine to be defined per aircraft. If you want to mix engine types you'll have to make the necessary changes by hand. Also note that all turbine, turboprop and rocket engines use the default "direct" thruster.

Note: After a configuration file has been generated and is displayed in your browser, you should select (via the menu) "View Source". This is needed because when viewing aircraft configuration files (for instance), some formatting is performed for web browser viewing, but if the file is saved in that format it will not work. The source for the page needs to be viewed, and the file saved with a '.xml' extension.

For more detailed instructions see the How-to


Step 1: The Engine configuration ... This step is not necessary if you are using an already existing engine configuration file. In any case you will have to edit the propulsion section of the aircraft configuration file to ensure that the engine name is the same as the name of the engine configuration file.


Engine Name
 
Engine Type
  piston  turbine  turboprop  rocket 
Engine Power or Thrust (per engine, without afterburning)
 
  horsepower  kw  pounds  newtons 
Augmentation (afterburning) Installed?
  yes no
Water Injection Installed?
  yes no


You are now ready to have Aeromatic generate your file. Aeromatic will create a file called engine2.php, which is your engine configuration file. You will need to save this file with a filename of the form engine_name.xml.





Step 2: The Prop configuration (if applicable)...

Engine Power (per engine)
 
  horsepower  kw 
Maximum Engine RPM
   
Pitch
  fixed  variable 
Propeller Diameter
 
  feet  inches  meters 


You are now ready to have Aeromatic generate your file. Aeromatic will create a file called prop2.php, which is your propeller configuration file. You will need to save this file with a filename of the form prop_name.xml.





Step 3: The Aircraft configuration ...

Chose a system of measurement

Engine Type
  piston  turbine  turboprop  rocket  electric 
Engine Layout
  fwd_fuselage  mid_fuselage  aft_fuselage  wings  wings and tail  wings and nose 
Yaw Damper Installed? (Almost all jets will need one)
  yes  no


You are ready to have Aeromatic generate your file. Aeromatic will create a file called aero2.php which is your configuration file. Save this file with a suitable filename, such as spitfireIX.xml. You will need to edit the propulsion section of this file so that the engine name is the same as the engine configuration file name, and the propeller name (if applicable) is the same as the propeller configuration file name.
