Steady-State Cycle Analysis
Analyze Brayton cycles, component maps, thrust, power, fuel consumption, pressure ratios, and off-design performance to optimize aircraft, industrial, and power-generation gas turbine concepts.
SimTurbo gives engineers, researchers, and university teams an engineer-friendly environment for designing, analyzing, and validating gas turbine systems. Model complete architectures, evaluate steady-state and transient performance, develop control logic, and visualize results in real time. From turbojet concepts to advanced recuperated cycles, the platform supports faster insight, more precise decisions, and practical virtual prototyping on standard PCs.

Specialized modeling, analysis, control, and education tools for gas turbine engineering teams and academic programs.
Analyze Brayton cycles, component maps, thrust, power, fuel consumption, pressure ratios, and off-design performance to optimize aircraft, industrial, and power-generation gas turbine concepts.
Build and configure complete gas turbine models with graphical, component-based tools for conceptual studies, component matching, shaft arrangements, combustor layouts, and performance optimization.
Evaluate dynamic engine behavior during starts, shutdowns, throttle changes, load shifts, environmental variations, actuator response, faults, and emergency operating scenarios.
Develop and validate PID control, fuel scheduling, FADEC logic, protection functions, gain scheduling, sensor models, and closed-loop transient response for turbine systems.
Model single- and dual-spool turbojet configurations, including compressor and turbine matching, combustor and nozzle behavior, thrust prediction, fuel studies, and operating-envelope analysis.
Support propulsion courses, laboratory experiments, capstone projects, faculty research, and student learning with academic pricing, classroom licenses, and industry-grade simulation tools.
SimTurbo helps technical teams move from gas turbine concepts to informed engineering decisions without treating the engine model as a black box. Its graphical, component-based environment supports steady-state and transient analysis, architecture development, control-law validation, and exportable results for Excel, MATLAB/Simulink, or Python. Real-time visualization on standard PCs makes it easier to compare configurations, investigate operating behavior, and refine designs with confidence.
