SimTurbo gives aerospace engineers, researchers, and educators an engineer-friendly environment for modeling gas turbine engines, evaluating performance, and validating controls. Build component-based architectures, investigate steady-state and transient behavior in real time, and export results for deeper analysis in Excel, MATLAB/Simulink, or Python. From concept studies to classroom labs, the platform helps turn complex propulsion questions into informed engineering decisions.
Specialized modeling, analysis, control validation, and educational tools for gas turbine propulsion engineering.
Configure complete gas turbine engine concepts with graphical components for compressors, combustors, turbines, shafts, and nozzles. Evaluate arrangements, component matching, and performance before committing to detailed development.
Analyze steady-state thermodynamic cycles, thrust, power, fuel consumption, pressure ratios, and component maps. Compare operating points and off-design behavior across altitude and ambient conditions.
Study engine startup, shutdown, throttle changes, acceleration, sensor response, actuator dynamics, and fault conditions. Assess dynamic behavior and stability to improve system response before testing.
Develop and validate PID controls, fuel schedules, protection logic, gain scheduling, and FADEC concepts. Test closed-loop behavior and transient response with integrated engine-system simulations.
Evaluate recuperated, regenerated, intercooled, reheated, and afterburning gas turbine configurations. Investigate waste-heat recovery, thermal efficiency, emissions considerations, and next-generation propulsion concepts.
Model single- and dual-spool turbojet systems, including spool interactions, compressor and turbine matching, nozzle performance, thrust prediction, control integration, and operating-envelope studies.
SimTurbo helps teams move from engine architecture concepts to defensible performance and control insights without treating the model as a black box. Its Windows-based, component-driven workspace supports real-time steady-state and transient simulation, interactive graphs, and data export for downstream workflows. Engineers can explore turbojet configurations, evaluate off-design behavior, validate control laws, and communicate results clearly across design, research, and education programs.
A specialized platform designed around practical gas turbine engineering work.
Build with graphical components instead of relying on an opaque engine-model black box.
Visualize throttle effects, transient behavior, diagrams, and interactive graphs on standard PCs.
J85-GE-21 validation reported accuracy within plus or minus two percent against NASA data.
University pricing and classroom programs support practical propulsion learning and research projects.
Experience-led guidance for advanced gas turbine simulation.
