JPRC Computer Controlled Jet Propulsion Study Unit


The Computer Controlled Jet Propulsion Study Unit, "JPRC", unit designed by Edibon allows the study of jet engines and propulsion fundamentals, and will allow students to delve into thermodynamic principles and efficiencies.

See general description

General Description

The main component of the Computer Controlled Jet Propulsion Study Unit, "JPRC", is a stator that has a conical inlet diffusion section for air to enter at low speed and high pressure in the combustion section.

The air, after being compressed, is subjected to combustion in a chamber where the atomized fuel is injected, to finally expand in an exhaust nozzle.

The air speed is provided by an axial fan allowing the operation of the ramjet.

An ignition system ignites the fuel/air mixture inside the combustion chamber.

The SCADA software of the Computer Controlled Jet Propulsion Study Unit, "JPRC", allows to represent the work cycle in T-S or P-V and calculates the thermodynamic efficiencies for the study of the jet engine.

It includes safety mushrooms and all the appropriate safety measures for safe work.

All determining parameters such as pressure, temperatures, fuel flow and pressure, air and exhaust gas flows, etc... are measured and monitored. In addition, the Computer Controlled Jet Propulsion Study Unit, "JPRC", allows the measurement of the thrust and drag of the jet engine.

With the recommended element Pulse Jet Engine, "JPR-P", it is possible to study another type of reaction engine, capable of generating static thrust. The main differences between a Pulsejet and a Ramjet can be studied.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.

Exercises and guided practices


  1. Demonstration and study of a ramjet system.
  2. Demonstration and study of a pulsejet system (requires the recommended element "JPR-P").
  3. Measurement of the total and static pressure along the Ramjet axis.
  4. Experimental determination of the thrust and drag of a Ramjet.
  5. Influence of the fuel flow on the operation of a Ramjet.
  6. Representation of the Brayton cycle in a T-S or P-V diagram.


  1. Many students view results simultaneously. To view all results in real time in the classroom by means of a projector or an electronic whiteboard.
  2. Open Control, Multicontrol and Real Time Control. This unit allows intrinsically and/or extrinsically to change the span, gains, proportional, integral, derivative parameters, etc. in real time.
  3. The Computer Control System with SCADA allows a real industrial simulation.
  4. This unit is totally safe as uses mechanical, electrical/electronic, and software safety devices.
  5. This unit can be used for doing applied research.
  6. This unit can be used for giving training courses to Industries even to other Technical Education Institutions.
  7. Control of the JPRC unit process through the control interface box without the computer.
  8. Visualization of all the sensors values used in the JPRC unit process.
  9. Several other exercises can be done and designed by the user.
