SimTurbo gives engineers, researchers, and university teams a practical environment for designing and analyzing jet-engine systems. Build component-based turbojet models, examine steady-state and transient behavior, validate control strategies, and visualize performance in real time. From early architecture studies to detailed operating-point analysis, the platform turns complex gas-turbine questions into actionable engineering insight on a standard PC.
Model, analyze, optimize, and validate gas turbine systems across design, performance, controls, and dynamic operation.
Configure complete gas turbine architectures with graphical components for compressors, combustors, turbines, shafts, and nozzles. Evaluate component matching, thermodynamic cycles, and conceptual engine configurations before committing to hardware.
Analyze Brayton-cycle performance, thrust, fuel consumption, efficiency, pressure ratios, and off-design operating points. Compare ambient and altitude conditions to identify practical opportunities for engine performance optimization.
Simulate startup, shutdown, throttle changes, acceleration, deceleration, actuator dynamics, sensor response, and fault scenarios. Assess dynamic stability and response before applying control concepts to physical propulsion systems.
Develop and validate PID control, fuel scheduling, start logic, protection functions, limiters, and FADEC-oriented strategies. Use closed-loop simulation to investigate stability, transients, and control-law behavior.
Model single-spool turbojet engines for compressor, combustor, turbine, nozzle, thrust, and fuel-consumption analysis. Support design validation, operating-envelope studies, educational demonstrations, and propulsion research projects.
Study high- and low-pressure spool interaction, compressor matching, turbine performance, controls, and off-design behavior. Build integrated dual-spool propulsion models for advanced engineering analysis and system optimization.
SimTurbo helps you move from a proposed jet engine layout to a transparent, physics-based model you can explore interactively. Its component-based graphical environment supports steady-state and transient simulation, performance prediction, control validation, and data export for Excel, MATLAB/Simulink, or Python workflows. Engineers and students can see how component choices, operating conditions, and throttle changes affect the complete gas turbine system in real time.
A specialized platform built to make advanced gas turbine simulation accessible, visual, and actionable.
Founded and led by an engineer with more than 45 years of cross-industry engineering experience.
Component-based architecture lets users inspect engine systems instead of relying on black-box models.
Interactive diagrams and graphs reveal transient behavior and throttle effects on standard PCs.
Reported J85-GE-21 validation accuracy is within plus or minus 2 percent of test data.
Experienced engineering leadership supporting simulation, education, and technical decision-making.

A jet engine simulator is used to model how a propulsion system performs before physical testing. It can predict thrust, fuel consumption, temperatures, pressures, spool speeds, and component operating points. Engineers use it for concept development, component matching, off-design studies, control development, troubleshooting, and virtual prototyping. Universities also use simulation to connect thermodynamics and propulsion theory with observable engine behavior.
