SimTurbo gives engineers, researchers, and educators a graphical environment to design, analyze, and validate gas turbine systems with confidence. Model complete architectures, evaluate steady-state and transient behavior, test control strategies, and explore advanced cycles in real time. Built for aerospace, marine, power-generation, and academic applications, the platform helps turn complex thermo-fluid concepts into practical engineering insight.
Explore component-based gas turbine modeling, analysis, controls, and advanced-cycle simulation capabilities.
Configure complete gas turbine architectures with graphical components for inlets, compressors, combustors, turbines, shafts, and nozzles. Compare arrangements, match components, and refine conceptual engine designs before committing to physical prototypes.
Evaluate Brayton-cycle performance, thrust or power, fuel consumption, component maps, pressure ratios, and off-design operating points. Use ambient and altitude studies to identify efficient operating conditions across mission or duty-cycle requirements.
Simulate startup, shutdown, throttle changes, acceleration, deceleration, load events, actuator dynamics, sensor response, and fault conditions. Examine dynamic engine behavior in real time to support stability testing and response optimization.
Develop and validate PID controllers, fuel schedules, limiters, protection logic, and FADEC-oriented strategies. Closed-loop simulation helps engineers assess transient response, gain scheduling, fault detection, and control-law behavior before implementation.
Model single- and dual-spool turbojet configurations for compressor and turbine matching, combustor analysis, nozzle performance, thrust prediction, and fuel-use studies. Apply detailed propulsion analysis to research, education, and aerospace design work.
Explore recuperated, regenerated, reheated, intercooled, and afterburning gas turbine concepts. Assess thermal efficiency, waste-heat recovery, emissions considerations, and performance tradeoffs for next-generation propulsion and power systems.
SimTurbo helps teams move from an engine concept to a transparent, component-based model without treating the system as a black box. Build configurations visually, adjust parameters quickly, and study steady-state or transient results through interactive diagrams and graphs. Export simulation data for post-processing in Excel, MATLAB/Simulink, or Python while testing performance, controls, and design tradeoffs on standard PCs.
A specialized platform for transparent, practical gas turbine engineering simulation.
Founder-led guidance reflects more than 45 years across aerospace, automotive, and power systems engineering.
Component-based architecture lets engineers inspect, configure, and understand the engine model rather than accept a black box.
Interactive simulations support immediate assessment of throttle effects, transient response, and control-law performance.
J85-GE-21 validation reports performance accuracy within plus or minus two percent against NASA test data.
Experienced leaders focused on usable engineering simulation.

Engine simulation software creates a digital model of an engine so users can evaluate performance before building or modifying hardware. For gas turbines, it can calculate thrust or power, fuel consumption, temperatures, pressures, component matching, and operating limits. It also supports design comparisons, off-design studies, troubleshooting, control development, research, and classroom demonstrations.
