WESTT CS/BV Virtual Engine Test Bench

The WESTT CS/BV is a multipurpose simulation test bench of the DGEN 380 and of its ECU (Engine Control Unit). This innovative and interactive tool is the ideal platform to develop insight into the characteristics of a turbofan engine.

It features:

  • A real time simulation of the main engine performance data
  • A dynamic 3D visualization of the engine
  • Thermodynamic and aerodynamic explorations
  • The DGEN control system with access to the engine regulation code

The WESTT CS/BV station is an ideal tool for up-to-date and practical education & research in a wide range of fields.

The simplicity of the engine’s architecture and its very high and its innovative technology make the station appropriate for all levels of study.

  • The reprogrammable regulation code and the failures simulation module allow for the study of the engine’s control system and its modern all-electric concept.
  • The simulated engine lends itself to proficient thermodynamic andaerodynamic explorations.
  • Dedicated 3D views are ideal for understanding the turbofan architecture, learning about the oil and fuel systems and practicing to engine maintenance.


The WESTT CS/BV is a hardware-in-the-loop system which contains the following elements.

Electronic boxes

  • The SIMMOT contains a simulated model of the DGEN 380. It recreates the experimental behavior of the engine and provides realistic engine data on a real time basis.
  • The ECU is the DGEN 380’s original engine control unit.
  • The BDI makes it possible to upload a modified FADEC program.


  • The manual controls are the master switch, the mode selector, the PLA and the flight conditions (Speed, Temperature, Altitude).
  • It is also possible to use software controls, to program automatic cycles and to trigger a wide spectrum of failures.

The test bench comes equipped with three display screens enabling users to control the simulation, to explore the three main educational modules (Thermodynamics, Aerodynamics & Control System) and to toggle between various visualizations.

Both theoretical and practical courses can be taught easily and efficiently with this all-integrated system.

In a classroom. The teacher can connect the station to a video-projector and use it to illustrate several theoretical principles e.g. velocity triangles in a HP turbine.

For a practical case studies. The station can be operated by groups of up to 3 students and can be remotely controlled by the teacher for blind troubleshooting. Price Induction supports its customers for an integration of the WESTT CS/BV in their laboratory in the best possible way.
Example of a Control System practical course: students work individually or by pairs on their PCs using the WESTT CS/BV dynamic block diagram model to prepare their regulation codes before testing them on the WESTT CS/BV station.

The WESTT CS/BV can also be configured to accommodate more students at once or be combined with other WESTT products to link virtual exercices with real ones.  Potential combination include the WESTT BH for the experimental analogy with the DGEN’s oil and fuel systems, or with the WESTT SE-HP or WESTT SEV stations for complementary applications in mechanical and maintenance engineering.



The simplicity of the engine’s architecture and its innovative technology make the station appropriate for all education levels including technical maintenance trainings, engineering studies, advanced R&D projects, lifelong trainings in aviation and pilot training.
