Our XSV package  simulates multibodied aircrafts and spacecrafts in the Simulink environment. We handle the dynamics of your simulation, so you can design control systems and do analyses. 

Please download the XSV models package also. It has all the models listed below.

Each model comes with a Demo license and an instruction file that explains how the model is built and how to run it. The instruction and the user's manual help you understand how to display the results and visualize the model after a simulation. 

The package runs with two other licenses, the Enterprise and Select licenses. Their capabilities are explained in the next table.

Buildx Edit Privileges for Three License Types

License Type ==>>

Enterprise Select Demo
Define mass, inertia, cm location yes yes no
Define Constraints: gear, position, directional, contact yes yes yes!
Define Initial State: dcm, angles, angular rates, wheel rates yes yes yes
Define Position and Directional Markers values yes yes yes!
Define External Forces and Torque yes yes yes!
Define Orbit (XSV only): Initial Keplerian coordinates yes yes no
Enable Gravity Gradient Force/Torque (XSV only) yes yes yes
Enable Prescribed Hinge Motion yes yes yes
Enable Flexible Body Dynamics yes yes yes
Multiple (N Body) Vehicle/Machine Simulation yes @ @
Define Hinge Type yes yes* yes*
Define hinge axis,hinge location,alignment yes yes no
Define Plot Data, Plant Dynamics Input/Output Data yes yes yes
Add/Remove markers,forces,constraints yes yes no
Add/Remove bodies, wheels yes no no
Define Model Connectivity: parent body designation yes no no
PC locked yes yes no
For a fee yes yes no
Note:   1. Select License lets you use the simulation package with assigned demo models in the MODEL_LIST                      2.  Enterprise License has all the Select License privileges and the privilege of modifying the connectivity of the model. 

! You can alter the attributes of these objects if they are already defined in the given model.

@If the downloaded model is already a multiple vehicle/machine model. 

* You can toggle the hinge motion type from dynamically determined hinge motion to prescribed hinge motion only.

Click the Package to download! 

XSV  Package contains Buildx.exe, Dynawiz1.dll(XSV), and QX3D.exe 
XSV Package installation procedure
Install this package to c:\xsv on your PC 

Download  and install XSV_MODELS.exe to c:\xsv\ folder. When done, all the models listed below would have been installed as subfolders to c:\xsv. Within each application folder, click on get_basics to complete the application files that are needed for executing the model editor(buildx.exe), dynawiz1.dll, and the animator(qx3d). Please read the installation notes in the application folders and the manuals that are in the c:\xsv folder.

Click 'view' below to see a static picture of the model, and 'animate' to see a short animation. The images and animations were generated using the QX3D program. 

Important: Your browser must be VRML compatible in order to view the model image or animation that are generated with QX3D. If not, install a VRML plugin (current Cortona VRML client: cortvrml.exe) from www.parallelgraphics.com  to view .wrl files.

XSV Models 

 Cube view/animate A single body satellite
 Cube_3wc view/animate A single body with 3 wheels for attitude control
 Sat001 view/animate A satellite with two arrays, each array with two panels. It has 3 wheels for attitude control. See array deployment.
 Sat_3panel view/animate A satellite with two arrays, each array with three panels. It has 3 wheels for attitude control. See array deployment.
 Dual_spnr view/animate A dual spinner with two jets on the rotor for spin-up.
 Cmg_sim view/animate A satellite with 4 control moment gyros for attitude control. Simulation demonstrates open loop slewing of the satellite along three body axis individually.

 Two_sat

view/animate Two satellites are initially attached to each other drifting in a LEO circular orbit. At 10 seconds into simulation, they are separated by a force pulse at the interface plane. One vehicle reorients itself into the LVLH attitude, the other maintains attitude hold. Gravity gradient forces/torque are exerted on the satellites throughout the simulation. This demonstrates dynamics with constraints, configuration change during simulation, and concurrently simulating two satellites.

 Chain20

view/animate A satellite with an array of 19 panels floats in a geosynchronous orbit. Initial bus angular rate is [1 2 3] deg/sec. No external forces are applied.
