Transient Operation Analysis
Simulate start-up, shutdown, throttle changes, acceleration, load shifts, faults, actuator dynamics, and sensor response to understand real-time gas turbine behaviour before physical testing.
SimTurbo gives engineers, researchers, and educators an interactive way to model gas turbine dynamics, evaluate transient behaviour, and validate control strategies before committing to hardware. Build component-based engine configurations, observe real-time responses to changing conditions, and export meaningful data for deeper analysis. The platform supports rigorous design exploration for aerospace, marine, power-generation, and university applications.

Explore specialised modelling, control validation, transient analysis, and educational simulation capabilities for gas turbine systems.
Simulate start-up, shutdown, throttle changes, acceleration, load shifts, faults, actuator dynamics, and sensor response to understand real-time gas turbine behaviour before physical testing.
Develop and validate PID controls, fuel schedules, protection logic, gain scheduling, and closed-loop responses for gas turbine engines and propulsion systems.
Configure complete gas turbine models with graphical components, cycle development, shaft arrangements, compressor and turbine matching, and performance-focused design studies.
Model single- and dual-spool turbojet configurations, evaluate component interactions, predict thrust and fuel use, and assess transient and off-design operating performance.
Evaluate recuperated, regenerated, reheated, intercooled, and afterburning cycles to investigate efficiency, waste-heat recovery, emissions, and advanced propulsion concepts.
Analyse thermodynamic cycles, pressure ratios, component maps, ambient conditions, fuel consumption, and operating points for gas turbine performance optimisation.
SimTurbo helps teams move from static assumptions to visible, testable gas turbine behaviour. Its component-based environment lets users configure systems, explore steady-state and transient conditions, and evaluate control responses without treating the engine as a black box. Interactive graphs and diagrams support faster interpretation, while data export to Excel, MATLAB/Simulink, or Python extends analysis into established engineering workflows.

SimTurbo combines engineering depth with an accessible environment for rigorous gas turbine simulation.
Observe transient effects and throttle responses interactively on standard PCs during simulation studies.
Build with drag-and-drop components instead of relying on an opaque engine model.
Reported J85-GE-21 validation accuracy is within plus or minus two percent.
Founder-led expertise draws on more than 45 years across complex engineering sectors.
Engineering expertise supporting practical, insightful gas turbine simulation.

Dynamic process simulation software models how a system changes over time rather than only calculating a fixed operating condition. For gas turbines, it can represent events such as engine start-up, shutdown, throttle movement, acceleration, load changes, sensor response, and actuator dynamics. Engineers use these models to evaluate behaviour, identify stability concerns, and validate design choices before physical testing.
