SimTurbo gives engineers, researchers, and students a graphical environment for building, analyzing, and validating gas turbine models. Explore steady-state performance, real-time transient behavior, control logic, and advanced cycle configurations without treating the engine as a black box. Component-based tools, interactive visualizations, and exportable data help turn complex propulsion concepts into clearer, faster engineering insight.
Specialized modeling tools for gas turbine architecture, performance, dynamics, controls, and advanced propulsion-cycle analysis.
Create and configure complete gas turbine architectures with graphical components for inlets, compressors, combustors, turbines, shafts, and nozzles. Evaluate arrangements, component matching, and conceptual designs before committing to physical development.
Analyze steady-state thermodynamic cycles, thrust, power, fuel consumption, pressure ratios, component maps, and off-design conditions. Compare operating points and optimize performance for aircraft, industrial, and power-generation gas turbines.
Simulate starts, shutdowns, throttle changes, acceleration, deceleration, load shifts, sensor response, and fault conditions. Assess dynamic stability and system behavior in real time for more informed design and validation decisions.
Develop and validate PID control, fuel scheduling, FADEC logic, limiters, actuator models, and engine-protection strategies. Test closed-loop response, fault detection, and stability before moving control concepts toward hardware integration.
Model single-spool and dual-spool turbojet engines with compressor, combustor, turbine, nozzle, and spool interactions. Study thrust, fuel efficiency, operating envelopes, transients, and subsystem performance for research or teaching.
Evaluate recuperated, regenerated, reheated, intercooled, and afterburning gas turbine configurations. Investigate waste-heat recovery, thermal efficiency, emissions considerations, and next-generation propulsion concepts through comparative cycle studies.
SimTurbo helps users move from an initial propulsion concept to meaningful engineering analysis through a graphical, component-based modeling environment. Build gas turbine systems visibly, then examine steady-state and transient performance, validate control logic, and compare design choices in real time. Interactive diagrams and graphs make model behavior easier to interpret, while data export supports deeper post-processing in Excel, MATLAB/Simulink, or Python.
Purpose-built capabilities help technical users analyze gas turbine systems with confidence.
Drag-and-drop components reveal system structure instead of hiding engine behavior inside a black-box model.
Interactive graphs and diagrams help users observe throttle effects and transient behavior on standard PCs.
J85-GE-21 validation results report accuracy within plus or minus two percent against NASA test data.
Founder-led expertise draws on more than 45 years across aerospace, automotive, and power systems engineering.

Mechanical simulation software uses mathematical and physics-based models to predict how a mechanical system will perform under defined conditions. For gas turbines, it can represent components such as compressors, combustors, turbines, shafts, and nozzles, then calculate outputs including thrust, fuel use, temperatures, pressures, and response to operating changes. It supports analysis before costly physical testing or prototyping.
