JPAD is a Java software library containing classes and utility functions that can be used to build software systems.
The typical user of JPAD is the aircraft designer, one who is interested in aerodynamic or performance predictions and in parametric studies. The principal focus of the library is the overall aircraft model, conceived as a set of interconnected and parametrized submodels: the wing and its variants (horizontal tail, vertical tail, canard), the fuselage, nacelles, the propulsion system.
JPAD comes with a set of modules, i.e. interdependent projects. These include:
jpad-configsjpad-corejpad-cadjpad-commander
JPAD has been in development since 2014. The codebase is provided here because we believe in the open source philosophy. Yet, only a selected subset of all functionalities is opensourced and made available in the "Express" release.
Caveat: Some features of JPAD depend upon a couple of native libraries that have been tested only for the Windows 64-bit platform. Hence, we provide instructions for Windows users. A Linux version of JPAD will be available once the library is declared stable and feature complete (release candidate 1.0).
Download and install:
- Java SE Development Kit 8
- Git bash for Windows
- Eclipse IDE
- Gradle
- e(fx)clipse plugin for EclipseIDE
- Gradle plugin for Eclipse
You can use a Git bash shell to clone the repository. Open the shell, establish a path where you want to download the files, e.g. C:\Users\John\Dev. At the shell prompt move to this position and issue the command:
git clone https://github.com/Aircraft-Design-UniNa/jpad-express.git
if you use HTTPS, or issue the command:
git clone [email protected]:Aircraft-Design-UniNa/jpad-express.git
if you have set up your shell to use SSH. See this guide to learn more. Alternatively, you can download the repository as a zip archive from this link.
Once you have cloned successfully the JPAD repository, e.g. from C:\Users\John\Dev, you end up with the subfolder jpad-express populated with all the necessary files to use the library. We call this folder <JPAD_ROOT>.
Open Eclipse and prepare to import a couple of projects that live in <JPAD_ROOT>.
From the menu File -> Import select the import wizard General -> Existing Projects into Workspace. Click Next. Chose Select root directory and browse to <JPAD_ROOT>. The japa-express project will be recognized by the wizard. Select the project and click Finish.
To run the test programs in Eclipse go to the menu Run -> Run Configurations. Explore the dialog that manages all the existing run configurations, which are stored as .launch files. Select a configuration from the left pane (in the Java Application group).
Before running a configuration do check the panels on the right pane. Explore the Main, Arguments and the Environment tabs. In the Environment tab make sure you edit the Path variable, which expands the JPAD_ROOT variable (see the string ${JPAD_ROOT}). Select the Path variable, click Edit, click Variables, click Edit Variables, finally create the new variable JPAD_ROOT pointing to the path <JPAD_ROOT>.
